361501 - use 'anonid' attribute inside anonymous content as ID attribute

Status: RESOLVED FIXED

(Core Graveyard :: XForms, enhancement)

Description

[alexander :surkov (:asurkov)]

Now XForms use 'id' attribute as ID attribute only. It makes hard to create XBL widgets that use xforms controls. For example, there is no way to work with xforms xpath index() function or xforms:toggle/xforms:case elements. That is nice feature to have.

That is looks like common problem. Sometimes for example, I like to use xul:label in anonymous content that is referred on certain control by 'control' attribute. Can we have common way to make 'anonid' attribute as ID attribute in anonymous content scope?

Comment 1

[alexander :surkov (:asurkov)]

Many xul/xforms/xhtml elements uses 'id' attribute for their work. For example, 'id' attribute is used by xul:label/xhtml:label to be linked with some element, xul:broadcaster, xul:command and so on. If I like use those elements in anonymous content then I can't use 'id' attribute for them. Idea to use 'anonid' attribute that is unique in context of XBL bound element is looks fine for me. But I haven't idea how it can be implemented. Any thoughts?

If it is ok to return NS_OK here, then we don't need the test for NS_SUCCEEDED anymore, right?  Please remove it since you are already changing this file.  Thanks.

nit: I'd suggest the following wording:

"Search for an element with the given ID value.  If the given node lives in the DOM, then we'll use nsIDocument::getElementById().  Otherwise, if the given node is a node that lives as anonymous content, then we'll search for the element using @anonid instead of @id."

>+   * @param aRefNode      Given node that is used to search referenced element.

nit: should aId comment be "The ID/anonid value to search for"?  And shouldn't you mention aElement?  Perhaps, "The element we found that has its ID/anonid value equal to aId"?

with those, r=me.  You might want to check with someone who is really familiar with XBL and mozilla if you haven't already, like bz, and see if he can think of any scenarios where this might not work well or might cause other problems.

As a side note, we need to look at the places where we call document->GetElementById prior to this patch and make sure we shouldn't have been using nsXFormsUtils::GetElementById instead.  Seems to me that we wouldn't handle items inside repeats very well for most of these cases.

Also, please look to see if we really need GetRepeatIndex exported like this anymore.  If the transformiix guys let us change this code, we might as well remove this call from the interface and just make it a utility function inside nsXFormsUtilityService.cpp.

I'd like to post new bug to DOM component to provide new method for nsIDOMNode. This things is needed already for us and for bug 362365.

Because this uses nsXFormsUtils::GetElementByContextId,
do we actually need both those methods?

This is a bit wrong, since the method seems to always call doc->GetElementById

So it is not quite clear to me when to call GetElementByContextId and when GetElementById.

I guess we need both methods since these are different things. nsXFormsUtils::GetElementByContextId() searches elements by @id and @anonid attributes. nsXFormsUtils::GetElementById performes additional actions if element is inside repeat row. I don't know good repeat code, so probably Aaron knows better?

I checked the comments in the new patch.  Perhaps change the wording of this, "// Search element with given value of 'anonid' attribute through complete
 // bindings chain. We must sure that currently traversed element is not
 // binding parent for itsleft to avoid infinite loop."

to:

"// Search for the element with the given value in its 'anonid' attribute 
 // throughout the complete bindings chain. We must ensure that the currently
 // traversed element is not the binding parent itself to avoid an infinite
 // loop.  The binding parent of a binding parent is itself"

No, I was just noticing that some of our .cpp files used doc->GetElementById instead of nsXFormsUtils::GetElementById.  Like trigger, and send.  I've double checked those and most of them are right...we shouldn't use nsXFormsUtils::GetElementById for elements that belong inside the model.  The only one that I THINK might be wrong is nsXFormsSetIndex.cpp.  But I don't know if it really is unless we test it to make sure it works.  I might be wrong.

nsXFormsUtils::GetElementById will, like Alex said, search through repeat rows looking for controls in addition to looking through the regular DOM.  For example, xf:dispatch dispatches an event to an element with the given ID.  If the element is in a repeat, you don't want to dispatch the event to the element in the DOM since we just end up hiding it and treating it as part of the repeat template.  So we use nsXFormsUtils::GetElementById to dispatch the event to the contol with that id that is in the repeat row that has the current focus (well, the repeat row that corresponds to the repeat's index).  If the element with that ID isn't in a repeat, then it picks the element with that ID from the DOM.  But you wouldn't want to use this call for items that you know can't be inside repeats (like instance or submission elements).  So for those we should use document->getElementById.  But since Alex created his nsXFormsUtils::GetElementByContextId() function, that is just as handy since it calls document->getElementById first anyhow and does the work of querying the document to use, too.

I use following wording:

 "// Search for the element with the given value in its 'anonid' attribute

Is it ok?

'patch7' is checked in by smaug on trunk

Comment 27

What should I do to get 'patch4 for 1.8' on 1.8 branch?

Is 'patch4 for 1.8' just for 1.8 or also for 1.8.0?  If it is for both, you should probably rename it to 'patch for 1.8.x'.  When I build the large single patch I use to update 1.8.0 and 1.8 to trunk-level code, I do it patch by patch out of the xf-to-branch bugs.  So if I see a patch for 1.8, I'll take that instead of the patch that was used for trunk checkin.

Comment 29

[alexander :surkov (:asurkov)]

Originally I plan it for 1.8 only. I didn't try it for 1.8.0. Do we still have plans to support fx 1.5?

We were going to do one more release for FF 1.5

Comment 31

[aaronr]

should this bug be marked xf-to-branch and resolved fixed or is there more work to be done on it?

I didn't try this on FF 1.5 since I haven't 1.8.0 tree. Can you test it?

I tried 1.8 patch on 1.8.0 tree.  Worked fine, though I had to do a clean rebuild of xforms.  I'm replacing that patch with this one to get rid of the windows line endings.

looking for an XPath signoff on this so that we can get it into the branches

Don't know enough XForms to review this, but it looks fine from an arch PoV.

Also, the patch should be safe to land on branch because none of the code it touches can execute without the xforms extension installed.

requesting approval for the branches.  This is a change, as noted by Jonas, that will only affect XForms users.  This change will allow people who write custom controls in XBL to embed xforms in the anonymous content and run standard xforms xpath functions (which look for xforms control with the given 'id') on these anonymous controls since the xpath functions would now be able to look for elements with the given anonid, too.

Well, I can r=me the extensions/transformiix parts. If that's all you need.

I thought we weren't approving interface changes on the 1.8 branch, only additions. Or does that not apply to XForms, even when the code is in transformiix?

I'm guessing that the rule wouldn't apply in this case.  This is an internal only interface that is kept in a header file (no corresponding .idl or .xpt file) so it could only be used by .cpp which isn't supported outside of XForms.

thanks for the explanation.
