1106412 - Menu items for "Edit draft" functionality missing after bug 321355 fixes "Edit as New Message" to do just that

Status: RESOLVED FIXED

(MailNews Core :: Composition, defect)

Description

[Thomas D. (:thomas8)]

+++ This bug was initially created as a clone of Bug #321355 +++

For messages in draft folders, bug 321355 fixes "Edit as New Message" menus to do just that: create a new copy of the draft and edit that. Unfortunately, thereafter there'll be no way of accessing "Edit (this) draft" functionality via menus (only "Edit" button on draft infobar). So this bugs adds "Edit (this) draft" to main menu's message menu and to the context menu, but only shown when we are in a draft folder. We'll want to use proper command layout to benefit from command attribute forwarding to UI elements which observe the central command.

MsgComposeDraftMessage() is commonly/consistently used for "Edit draft".

Needed action is;

Mail composition related menu/menuitem is now busy, so "hiding menu/menuitem if not usable(disabled)" may be better.
Note:
When multiple messages are selected at threadPane, appMenu(main menu) is not altered, but Context menu is drastically changed : No mail composition related menu except "Forward as Attachments".

Patch for Bug 321355 is one liner patch. It simply stops "setting previous/editing DraftId upon composition start by Edit As New".

This is done in mime-parser(mimedrft.cpp). i.e. it's set upon parsing existent mail data for edit, forward etc.
Trick in original "Edit draft"(double click at Drafts) / "Edit As New" was "if folder is not Drafts folder, original DraftId is ignored".
i.e.
Before bug 321355 : Edit As New at non-Drafts = Edit draft + Don't delete original upon first draft save/send 
                                  Edit As New at Drafts         = Edit draft(==deletes original upon first draft save/send)
                                  Edit draft at Drafts             = Edit draftl(==deletes original upon first draft save/send)
After    bug 321355 : Edit As New at any folder  = Edit template(==doesn't delete original upon first draft save/send)
                                  Edit draft at Drafts             = Edit template + Deletes original upon first draft save/send

Following is currently used interface for "Edit As New" and "Edit(draft)".
ComposeMessage() is finally used used in both case.
composeMsgByType used by EditAsNew was for "Shift modifier" handling.

After patch for bug 321355, I think "delete of original draft mail in Edit draft" won't be executed, because fields->SetDraftId(mdd->url_name) is removed by the patch.
"What is needed for editDraft after bug 321355" is "set previous/editing DraftId upon composition start" at somewhere.

draftId is set at https://hg.mozilla.org/comm-central/file/3f82c17bf9af/mailnews/mime/src/mimedrft.cpp#l1487

You don't need to worry about draftId in case of "Edit" in drafts folder.

But your patch removes the line...

> You don't need to worry about draftId in case of "Edit" in drafts folder.

I guess why "Edit As New at Drafts folder currently deletes edited mail" is as follows.
I couldn't find code which sets draftID of edited mail when composition-type=Draft is requested via Edit button/double click at Drafts folder, except mimedrft.cpp#1487.
I could find logic of "if composition type=Draft, deleteDraft=true" only.
How "edited mail in Drafts folder" is deleted if Edit button/double click at Drafts folder, after mimedrft.cpp#1487 is removed?

Why "edited mail is not deleted upon first draft save/send if Edit As New of non-Drafts folder even if draftID is set" is;
    draftID is set by mimedrft.cpp#1487,
    but if compositin-type=Template is requested via. "Edit As New" menu at non-Drafts folder,
    deleteDraft=false is intially set, so "delete editing mail" is not executed upon first draft save/send.
    And, when draft save happens, URL of newly saved draft is set in draftID, and deleteDraft=true is set.
    Note: Following is actually ofserved phenomenon.
         When "Edit As New" at Template, initial state is : draftID=edited template, deleteDraft=false
         After Save"  :  draftID=newly saved draft(==currently edited mail), deleteDraft=true
Why "edited mail is deleted upon first draft save/send if Edit As New of Drafts folder" is;
    (a) draftID is set by mimedrft.cpp#1487,
    (b) but if edit at Drafts folder, even if "edit of mail" is requested with compositin-type=Template by "Edit As New" menu,
          deleteDraft=true is set(it's perhaps because of "Edit *AT* Drafts folder),
    (c) because draftID is set and deleteDraft=true, "editing draft" is deleted upon first draft save or send,
          and URL of newly saved draft is set in draftID.
Your patch removes mimedrft.cpp#1487.

The patch removes another SetDraftId().

Gotcha! Sorry for my confusions.
If no draftID when Template request, "delete mail in draftID" can't occur at any folder when "Edit As New" :-).

Sorry, I msundestood test results.
When "Edit As New of non-Drafts folder", draftID=original mail, deleteDraft=false was set, and original mail(in draftID) is not deleted upon "Save as draft", as I previously wrote.
However, when "Edit As New of a draft mail in Drafts folder", draftID=edited draft, deleteDraft=false was set, but edited draft=original=draftID was deleted upon save(problem of .bug 321355).
If draftID is set, and if Drafts folder, Tb always deletes draftID regardless of deleteDraft upon draft save/send?

Comment 8

[WADA:World Anti-bad-Duping Agency]

FYI.
Why "edited mail by Edit As New is deleted if Drafts" but "edited mail by Edit As New is not deleted if non-Drafts" is perhaps:
> http://mxr.mozilla.org/comm-central/source/mailnews/compose/src/nsMsgCompose.cpp#3674
>    After end of SaveAsDrft/SaveAsTemplate/QueueForLater/DeliverBackground,  RemoveCurrentDraftMessage() is called.
> http://mxr.mozilla.org/comm-central/source/mailnews/compose/src/nsMsgCompose.cpp#3728
>   if draftID  is not set, RemoveCurrentDraftMessage does do nothing.
>   if draftID is set && folderFlags has nsMsgFolderFlags::Drafts, RemoveCurrentDraftMessage deletes draftID.
>   even if draftID  is set, if folderFlags doesn't have nsMsgFolderFlags::Drafts, RemoveCurrentDraftMessage does do nothing.
Pretty small mismatch on "delete original or not" is seen in composer component modules.
    Someone deletes originl if draftID is set && deleteDraft=true regardless f folder type,
    but other someone deletes original if draftID is set && folder is Drafts folder regardless of deleteDraft.
This is perhaps difference between "process during mail composition" and "post save/send process".

Comment 9

[WADA:World Anti-bad-Duping Agency]

FYI.

By patch for bug 321355, "Edit As New" won't delete "edited mail" even at Drafts folder, and if editDraft requests with composition mode=Draft as done currently, "edited mail" is still deleted as expected as far as it's requested at Drafts folder..
 
As seen in Bug 731688, "Shift modifier" is better used in "mail composition related XUL elements" commonly/consistently.
Such thing is already sorted out in Forward/Reply relevant elemetnts.
So, "ForwardInline" is  better used as template of both "editAsNew" and "editDraft".

If I try to create patch, I want to do change like next, because I dislike coding like current one : What is actually executed is unknown until deeper level function is read.
I like "What is actually done is coded in main module, subfunctions is helper of mail module" style.

i.e. If I create patch, I want to do excess changes which may produce regression in other components :-)
And, I don't want to decide about function name, label string, etc.
Further, I don't know "how to create patch for Mozilla family"  :-)
Therefore, I can't create patch for this bug.

Thomas D., UI part of Bug 731688(add Shift support in Edit As New) and UI part of this bug(Edit draft) are same, exept used name/string/label and except "hiding menu if non-Drafts in this bug".
Can you create UI patch for both?

Ikezoe-san, thanks for quick WIP v1.
Do following change, please.
(1) Inherit from "Forward in Inline" which supports Shift, in both "Edit As New" & "Edit Draft".
(2) Function Name = MsgEditDraftMessage instead of MsgComposeDraftMessage, for consistency with cmd_editDraftMsg,
(3) Add "Hide editDraft menu if not Drafts" code to onpopupshowing event handler.

If replacing some patch lines, I can do it, but for no control statement part, I can't modify...
Can you start with at least "inheriting from Forward in Inline" with consistent function name and commad id?
And, please include control statements for added/replaced functions and two onpopupshowing modules.

Comment 16

[WADA:World Anti-bad-Duping Agency]

FYI.
Difference between "Edit As New" and "Edit draft" is composition-type = Template or Draft only at UI level.
So, single MsgEditMessage(EditType,event) can be used in both command, if <command id="cmd_???" oncommand="MsgEditMessage(this.id,event)"/> is used.
Further, it's applicable to any function of Msg???(event) for mail composition related menu.
command_id and function name/structure was cleanly, clearly sorted out by great effort for improvements/sorting out of Reply/Forward related feature.
So, if <command id="cmd_???" oncommand="MsgInvokeComposerForExistentMail(this.id,event)"/> is used, single MsgInvokeComposerForExistentMail(RequestType,event) is currently sufficient, except for "Compose New Message".
Because id of command is chosen pretty well and it's abstract name of "requested feature", it's usable at any place for knowing "which feature is requested by user".
This technique can be called "modified goDoCommand to support event object passing for Shift modifier".
Needless to say, enhancement/improvement of goDoCommand interface is better : 
   if goDoCommand() is goDoCommand(ParmObject) and the ParmObject is passed to invoked functions,
   we can freely use <command id="cmd_???" command="goDoCommand( {event:event, cmdID:this.id, p1:"xxx", ,,, } )"/>.

[WADA:World Anti-bad-Duping Agency]

FYI.
Because "Edit *AT* Drafts/Templates folder" and "Edit *AS* Draft/Template" is clearly isolated by bug 321355, following is possible.
  Edit As New at any folder    = Compose new mail from this template : Don't delete edited mail, Send is possible <= bug 321355
                                                  If Templates or Drafts folder, label of menu better changed from "Edit As New"?
  Edit draft        at Drafts        = Continue mail compositiont : Originlal is deleted by save/send, Send is possible <= this bug
  Edit template at Templates = Modify this template : Mail is replaced by new version upon save, Send is prohibited <= Needed?
                                                 Note: absolutely same as "Edit draft", except "Send is prohibited". Shift works too.

Question about ThreadPaneDoubleClick().
1. Why ComposeMesssge() is directly called for Templates folder but Msg???() is called for other folders?
2. "When single statement in if-then-else, don't use {} in if-then-else" was coding style in Mozilla family, wasn't it?
     Or it was "When if/else is single line with single statement"?

Alright..., thanks for the pointer :)

So here's the new patch, based on the groundwork of attachment 8531807 [details] [diff] [review] and attachment 8531870 [details], only better! E.g. using global command attribute forwarding instead of clumsy references to each and every menu.

I tested this in my local installation and it seems to work as expected for all 3-pane use cases. Hiding "Edit Draft Message" is not yet implemented for context menu of global search results in tree-style - I'd need help on that one or we can do it in a followup bug.

Caveat: Due to bug 321355, "Edit as New" command does NOT work for drafts yet, both before and after this patch.

Comment 22

[Thomas D. (:thomas8)]

Attachment: WIP Patch v.3

This patch is cleaner and now also works on context menu of global search tree-style results. It also correctly shows a disabled "Edit Draft Message" menu (from the main menu) when there's no message selected (use Ctrl+Click to unselect current msg).

Known issues:
1) Once "Edit Draft Message" is disabled (for menus without selected messages), it does never re-enable again, so the functionality is henceforth not available until restart of TB.
I have not been able to track down the cause of this, and I'm surprised that it happens, because I think that I've tracked every corner where we have "Edit as new" and the "Edit Draft Message" command is just an exact duplicate of that. So why does it behave differently then? Fyi, "Edit as new" correctly re-enables.
Any ideas?

2) The Shift modifier to compose in non-default format does not seem to have any effect in my setup (yet to test without addons). This may or may not be an error of my patch (I think not).

Perhaps because I haven't set oncommand with direct function call on the menuitems, but was using command instead (which forwards to oncommand on the command itself), which is more correct, but perhaps it doesn't always work as expected.

Thanks for rapid review. However, as stated, I'd appreciate your help to *debug* this patch because it is NOT working correctly. See comment 22.

While we can easily postpone the shift-modifier problem to another bug, I'm not happy with this:
1) Ensure that no messages are selected in message pane of a draft folder (Ctrl+click to unselect a selected msg).
2) Main menu > Message > (look at) Edit Draft Message (correctly disabled)
3) Select a draft msg and *right-click* for context menu > (look at) Edit Draft Message (wrongly disabled).
Interestingly, this only happens for exactly that sequence of steps. If you select a msg and then go to the main message menu first, the command will be correcty re-enabled for all menus.
So there's a different pattern between the main message menu and the mailcontext menu, and the mailcontext menu is lacking something or doing something odd in command updating which the message menu has or does correctly.
Maybe something around this setSingleSelection function which is only on the context menu.

So which problems does this actually fix? None of the problems mentioned in comment 22 anyway.

> You made a good number of copy/paste mistakes ;-)

No, I didn't. Every deviation was well-considered and working; only wrt to comment 22 we still need to find the reason why it fails on those edge cases. Unfortunately it's you who is introducing copy/paste issues which are not seen on my patch:

JK added:
> <key id="key_editDraftMsg" key="&editDraftMsgCmd.key;"
> oncommand="goDoCommand('cmd_editDraftMsg')" modifiers="accel"/>
> <!ENTITY editDraftMsgCmd.key "d">

This conflicts with Lightning's keyboard shortcut for "New Task" (Ctrl+D).
Most other possible keyboard shortcuts are taken.
Plus we don't really need nor want to add a keyboard shortcut for "Edit Draft Message" because we already have two keyboard ways for that:
* Enter (!)
* Alt+E (which wfm even though it seems to conflict with main menu's Alt+E for Edit menu).

JK added: 
> <menuitem id="mailContext-editDraftMsg"
>           label="&contextEditDraftMsg.label;"
>           accesskey="&editDraftMsgCmd.accesskey;"
>           oncommand="MsgEditDraftMessage(event);"/>

I had deliberately omitted the access key on the context menu because it conflicts with "D" access key of "Delete Message" command on context menu. All other access keys from the "Edit Draft Message" string are also taken.
Conflicting access key are undesirable (although they don't break the thing). Given the easy and straightforward keyboard accessibility options above which will directly edit the selected draft message (Enter / Alt+E), plus a big [Edit...] button on an even bigger notification bar, using the context menu is a very unlikely scenario for this particular command, and should not be encouraged. Delete also has "DEL", but I'd still think it's slightly more likely to be accessed from context menu then Edit Draft, so I wouldn't want to take away or tamper with its access key. So I guess it's reasonable and acceptable in this exceptional case to omit the access key for "Edit Draft Message".

Furthermore, unless changing command="cmdname" to oncommand="function..." attribute actually helps (which I don't see yet), we should keep the more correct style of using command attribute.

> (I'm still embarrassed about the r+ I gave.)

If there's a need to use strong words like "embarassed" at all (which also seems to suggest that my patch is so obviously pretty bad, which is not true; it's 98% working as designed), make sure you're embarrassed about the right thing. Nothing wrong with your review. More likely your patch and its presentation.

> Note, you don't hide commands, you hide elements of the document.

It's not about "hiding commands" as such. As documented in comment 0 and comment 21, I've correctly used an intelligent inbuilt XUL feature called "Command Attribute Forwarding" (1). All elements having the command id in their command attribute will automatically observe attribute changes broadcasted by the main <command> element. (We could even define the command label on the command only and it would be forwarded to all the observing menu elements, but I refrained from that for certain reasons). Which works like a charme, and makes for streamlined, robust and easily maintainable code.

More specifically, instead of clumsily setting attributes on each and every element using hard-coded IDs...

> document.getElementById("menu_editDraftMsg").setAttribute("hidden", hideEditDraftMsgCmd);
> document.getElementById("mailContext-editDraftMsg").setAttribute("hidden", hideEditDraftMsgCmd);
> document.getElementById("appmenu_editDraftMsg").setAttribute("hidden", hideEditDraftMsgCmd);

...we can just use a single line to change the attribute on the central command and all of the above elements which have command="cmd_editDraftMsg" attribute will observe that change automatically:

> document.getElementById("cmd_editDraftMsg").setAttribute("hidden", hideEditDraftMsgCmd);

Then, if we or addons later decide to add e.g. another UI element for the same command, you'll just add command="cmd_editDraftMsg" attribute on the element and it's all hooked up and behaving correctly. Same if we decide to shuffle our UI or change element IDs, just keep the command hook and you're safe.

> Please try this. I gave it a brief test and it looks good.

Unfortunately it just adds unnecessary and problematic code but does not fix any of the issues of comment 22 per my testing...

Comment 34

I may have messed up an access key, but you can easily fix that.

Comment 35

[Jorg K (CEST = GMT+2)]

The problem you describe is this:
You're using the "elegant"
document.getElementById("cmd_editDraftMsg").setAttribute("hidden", hideEditDraftMsgCmd);
and therefore on the context menu you need to put:
    <menuitem id="mailContext-editDraftMsg"
              label="&contextEditDraftMsg.label;"
              accesskey="&editDraftMsgCmd.accesskey;"
              command="cmd_editDraftMsg"/>  <=======

My working solution uses:
document.getElementById("mailContext-editDraftMsg").setAttribute("hidden", hideEditDraftMsgCmd);
and
    <menuitem id="mailContext-editDraftMsg"
              label="&contextEditDraftMsg.label;"
              accesskey="&editDraftMsgCmd.accesskey;"
              oncommand="MsgEditDraftMessage(event);"/>  <======
Like this, your problem doesn't occur. Also, you get the event passed, since this is what you want.
If you look at the other context menu items, some/most use "oncommand".

So your intelligent solution doesn't work, but my dumb copying does(*). Sorry, you didn't make copy/paste mistakes, you deliberately chose a different (non-working) solution. Maybe it can be made to work.

There, I helped you debug it, so now you figure out what you want to do.

Please note that in my patch I fixed a few nits, like I made the "let hideEditDraftMsgCmd" readable.

Comment 36

[:aceman]

Using command is preferred if it works as you can share the code (function call) to be run.

On the other hand, if you need the 'event' you must test whether the event fires on the <menuitem> or the <command> element.

We have some bugs about converting to <command> globally, but I am not sure if it make sense now, when whole XUL is on the way out.

Precisely. That function sets the enabled/disabled only on the mailContext-editAsNew menuitems (in context menu) itself, while the menuitem is also observes the command cmd_editAsNew and their values are now conflicting.

I am working on a solution. We need to update the command and but also hide the menuitem if needed (but not hide the whole command). The problem is, the command may be disabled and no msg selected, but if you right click a message (without clicking it to preview it) the menu item should be enabled (as all others are). So maybe that is why the mailContext-editAsNew was NOT observing a command. So we could do that for editDraftMsg too.

This also doesn't work for the original Edit as new message. It's probably because the goDoCommand() (in the declaration of the command) does not propagate event.

Anyway this should be pursued in another bug, it is a separate feature.

This is Thomas' original approach of hiding the command. Sadly, since the context menu doesn't use the command, it's not hidden from the context menu in a non-drafts folder.

Just !document.getElementById("cmd_editAsNew") can't work. If you meant document.getElementById("cmd_editAsNew").hidden, then that could maybe work, but we set the state via attribute so I check it back via an attribute (not property).

You didn't see the ... I didn't want to copy the whole thing. I meant:
! document.getElementById("cmd_editAsNew").getAttribute("hidden")
But the attribute comes back as a string, OK, then that's fine.

Well, I'm not convinced. If ever we want to hide it in the future, we will do so. And the "edit draft" can serve as model. Please, let's not half-implement something with the view to do something else later. "Edit as new" was never hidden, and I don't see it coming.

Why keep the infrastructure for two very different things the same. "Edit draft" only applies to draft folders, so it needs special treatment.

People will get confused and look for the hiding of the command and not see it.

Maybe there could be accounts where the items displayed are no messages so "edit as new" makes no sense?
Like the IM accounts. Fortunately, those do not use the main 3pane view but their own tab and commands.

Yes, I can imagine this :)

Perfect. Thanks to all involved, especially to Thomas for getting the ball rolling to clean up this area.
Note that bug 321355 is also ready to land when current bustage is resolved (in fact, it was landed on Aurora already).

Thanks :)
This could use porting to Seamonkey later.

Is there any reason this is not landed on comm-aurora? It sounds like a regression that we need for TB45.

Comment 51

To edit a draft, you double click it or use the big "Edit" button in the notification area. Having this on the menus is nice but not necessary. Certainly not a regression. The bug has some string changes, so no uplift here.
