using the build from 5/26 on win98

If I bring in a document or if I create a new document and I toggle through the 
modes, then in wyiswyg mode or html source mode I add additional elements, then 
toggle back to Show All Tags mode, some of the icons are missing.

Are you sure this isn't the bug where tags/content added in HTML Source mode
are sometimes lost when switching to any of the other modes? Confirm this
by using Debug | Output HTML after changing out of HTML Source and observe if
all of the new tags/content was pasted correctly into the "normal" document.

no, none of the elements are lost, the text and element are still there, just 
the element icon does not display.

ah thanks Charley -- but, here is the steps I did to reproduce this:
1. open New Blank Page, stay in default Normal mode
2. add 4 lines of text, tag the first line as a heading. Highlight some text 
(not all) in the second line and make it bold element, highlight some more text 
in the second line and make it italic. Highlight the 4th line and mark it as a 
3. select the Show All Tags mode. You should see the BODY element icon, the 
first line of text should have a heading element icon, the second line of text 
should have a bold and italic element icon, the fourth line shuold have a 
paragrapgh element icon
4. Toggle back to the Normal mode and then toggle back to the Show All Tags 
mode. All of the element icons except for the BODY element icon have 
disappeared. The text is still present, nothing has been deleted.
5. select HTML Source mode, you will notice that all of the elements are still 
6. Toggle back to the Show All Tags mode, highlight some text on the third line 
and mark it as underlined
7. Toggle back to the Normal mode and back to the Show All Tags mode -- the 
underline element icon has now disappeared.
8. Toggle back to Normal mode -- notice everything renders as you marked it, 
nothing is deleted, it's just that in the Show All Tags mode, the element icon 
representations are not displayed.

We are having problems dealing with some tags, so the 2nd file removes those.
Marc: We are now seeing problems displaying the background images for the tags.
What I'm seeing today is that the first time I use "Show All Tags" mode, all
of the "icons" (background images on the tags) display ok. Then switch back
to normal, and then use "Show All Tags" again. All of the icons except "body"
are missing after the 2nd try. 
After the first stylesheet load, we are storing the override style sheed as 
a member variable of the editor as a COM ptr, then reloading it each time "Show 
All Tags" is used again.
Since you seem to understand the CSS/background image issues very well, you
seem to be the best candidate to investigate this.

I'll look it over... Charles, instead of unloading and reloading the style sheet 
why don't you just enable/disable it? I recently added code to check if a 
stylesheet is enabled before using it in the cascade (somehow that bit was never 
checked before). It might be faster for you, especially if the stylesheet is not 
changing, you know, like, it's a static css file we distribute with the

Good suggestion! Does enabling/disabling work with override sheets?

I found nsIStyleSheet::SetEnabled(). We store as nsICSSStyleSheet, so this
will be easy. Thanks!

Comment 13

eMail from Charles Manske:

Well, I tried using nsIStyleSheet::SetEnable and I still see the bug. I'm not 
sure if the existing code does this, bug: After the first use of
"Show All Tags" mode, then 1st switch back to "Normal", the "body" icon is not 
removed (I think we saw that problem before, correct?)
Then if you use "Show All Tags" again, the other icons don't redisplay, just as 
they don't now (using RemoveOverrideStyleSheet).

Comment 14

18 years ago
Marc I don't know if this is related or not, but on win98, when I toggle to HTML 
Source and back to either Normal or Show Tags, I lose all of the data that was 
within the body. I will open a bug for that.

Comment 15

18 years ago
Zoinks! that doesn't sound like a style problem, Beth. Please CC me on the new 

I winder if there is a more fundamental problem here... The Show All Tags stuff 
worked, albeit for only a brief period, but I played with it at length when I 
fixed the background color problems. I don't really understand how the editor 
handles the document being edited, so I am having a hard time emulating what is 
going on in the editor in simpler testcases. 

Beth, what is the priority on this specific bug? Right now it is kind of low 
priority for me (not nsbeta2, not dogfood, not blocker) so I'm only looking at 
it in my spare cycles...

Comment 16

you're right, this should be bumped up, I will nominate for nsbeta2 -- this 
could really confuse users if they toggle, you get the impression that data is 
being removed.

Comment 17

18 years ago
I'm not sure if this is a separate issue, but I tried using 
nsIStyleSheet::SetEnable(PR_FALSE) instead of removing the style sheet to 
transition from "Show All Tags" mode to "Normal", as suggested by Marc,
and when I do that the icons are removed from the page, but not the padding
that is used to reserve space for the icon (which is a background image).
I.e., disabling a style sheet that has "padding-left: 20px;" doesn't trigger
redisplaying the page to remove the padding (act like "padding-left: 0px").

Comment 18

18 years ago
Charles, when a sheet is enabled or disabled the document associated with it is 
notified, which causes a bunch of other things to be notified, notably the 
PresShell which then does a reframe. If the StyleSheet does not have an 
associated document then none of this happens. I thought that was what I was 
seeing when you were doing the Load/Unload logic, the sheet had no document. 
Somewhere the style sheet needs to have the document set, by calling 
SetOwningDocument. Are you setting the document when you load the stylesheet?

Comment 19

18 years ago
Another possibility is that CSSStyleSheetImpl::SetEnabled could use the 
CSSStyleSheetImpl::GetOwningDocument method to get the document to notify rather 
than just using the mDocument data member... This would only help if the parent 
of the style sheet had a document but the style sheet does not, probably not 
this bug. It may be a good idea anyway, since it would take care of enabled 
child sheets (which will not work now).

Comment 20

18 years ago
We weren't setting the document when loading the sheet before, but I discovered
that problem and added that to use SetEnable. So my tree has that fix, but
that didn't seem to cure the buge.
I sent that to you as part of the diff, which I'll attach the bug.
Maybe I should try to get permission to check that in today.
Would you prefer if I also checked in the code to use SetEnable() instead of 
the current load/unload code?

Charles, I think the Enable/Disable method is better, as well as easier to 
debug. Since neither methods work any better or worse I'd suggest using the 
Enable/Disable method. 

I'll try and apply the patch and see what happens. I'm assuming that you are 
running against tip layout code?

Also, with the SetDocument call in there are you at least seeing the layout 
problem fixed?

Comment 24

To answer Marc: No, setting the document didn't seem to fix anything.
I disagree with the nsbeta2- assessment and would like reconsideration:
We are loading/unloading, enabling/disabling style sheets to do the "Show
All tags" mode. And as a result we are simply setting background images on tags 
when the sheet is loaded/enabled. The fact that this doesn't work is not just 
an isolated editor issue, but reflects something more fundamentally wrong with 
style sheets and/or background images. It seems those basic issues need to 
be addressed sooner than beta3.
Note also that this is a regression -- this all worked a couple of weeks ago.

Rick: It would be helpful if I could be allowed to checkin the code in the

stylesheet usage.
The impact on the user is that the "Show All Tags" editmode, which is a 
completely new, innovative way of editing is totally unusable, and we were
hoping to get some good feedback about this in Beta2.
As I argued above, it reveals some basic problem with loading/unloading, or
enabling/disabling stylesheets that I feel is better addressed sooner than 

Comment 27

18 years ago
It's a common tendency to believe that a problem which lies in a different module 
reveals a basic flaw with wide implications but in that particular case, I 
wouldn't use this argument to raise the priority of the bug. The real question on 
your side is: do we need Show All Tags for beta2? The PDT team didn't think so. 
You may argue the case with Beth but I don't think you can claim basic flaws in 
the style system to help your cause:
- We enable/disable stylesheets when switching between quirks mode and standard 
mode and AFAIK there isn't any problem.
- We used to load/unload style sheets in the Editor for the (now defunct) Apply 
Stylesheet command and there wasn't any problem either.
- When reproducing the bug using beppe's comments from [2000-06-02 13:38], the 
icons are indeed missing but you can also notice that they are replaced by an 
empty space which corresponds to the size of the icon, meaning that the style 
wasn't completely lost: just the icon. Most importantly, if you quit the app and 
modify the stylesheet (EditorAllTags.css) to display backgrounds of different 
colors instead of icons, it works: the style is applied/removed and you can 
toggle between modes.

If this is a style problem, it is limited to the 'background-image' property (and 
Marc may want to have a quick look because he worked in that area 1 or 2 months 
ago) otherwise it could be another tricky bug with image loading and the Cache.

Comment 28

18 years ago
There isn't any problem with the background-image property either. I did a quick 
test where I used the following line in EditorAllTags.css for the B and U tags:
       background-image: url(http://bugzilla.mozilla.org/ant.jpg);
then I followed beppe's instructions to reproduce the bug and the image didn't 
disappear for B and U elements.

This is not a style problem, removed the [NEED INFO] tag, reassigned to cmanske. 
It could be another image loading problem between ImageLib, Cache and History.

Charles: a good test would be to replace the 'chrome:\\' urls with 'http:\\' urls 
of the same icons on a remote server then with 'file:\\' urls on your local

really? So, you're anew user using Composer and you type your little heart out 
and select Show All Tags to see what this HTML stuff is all about. ANd you say 
-- hey that's pretty cool. SO you toggle back to the Normal mode because you 
don't feel comfortable in the show all tags mode, and you enter more stuff - and 
want to sneak a peek at the new stuff in show all tags mose -- BUT WAIT: your 
stuff is gone - and you call that low impact? What am I not understanding?

Beth, I can't get the content to disappear, just the icons. Is it on Win98 only? 
Is the content really gone or does it come back after doing a resize or switching 
back to HTML Source?

Comment 32

18 years ago
Beth, I could reproduce the problem on Win98 (albeit running in VirtualPC). The 
easiest way for me to reproduce it is to click repeatedly on "Normal" while the 
document is still loading in the "HTML Source" mode. If I wait until the document 
is fully loaded in "HTML Source" mode, then click on "Normal", the problem 
doesn't happen.

When the problem does happen, the content always comes back after either resizing 
the window or switching back to the previous mode. Both are fairly easy

Independent of whether we identify and fix the image appearance problems for
beta2, can I *please* checkin the simple patch attached above.
All of you except Marc and I are using code that is not "correct" and 
this is a waste of time.
As Marc has pointed out, we need to set the document when first loading the
stylesheet, and then use SetEnabled(PR_FALSE or PR_TRUE) to disable and reenable
the sheet instead of unloading are reloading it. With this code in, we can 
correctly evaluate where the problem really is.
This is a very safe fix even if we don't make any further changes before beta2.

Marc: The code to use SetEnabled() is checked in.
We now have the additional problem that when switching from "Show All Tags"
mode to "Normal" or "Preview", the extra padding-left used in the CSS for 
all the tags is not removed when SetEnabled(PR_FALSE) is used to turn off
the EditorAllTags.css override sheet. Could you please investigate that problem?

Comment 37

18 years ago
I am also noticing the after switching back to "Normal" from "Show All Tags"
mode, and then creating new content (e.g., click on one of the list toolbar
buttons), the new content is shown with the icons that should only display
in "Show All Tags" mode. Thus while Pierre is probably correct that the image
disappearance is not a CSS problem, the latest issues I described
are CSS-related. Marc doesn't have any other pressing bugs and would like
to look at these new problems -- he was on vacation yesterday and we would 
like a couple more days to investigate.

Comment 38

18 years ago
Looking into this I have found a problem with Enable/Disable of the StyleSheet. 
Basically, we use the enable-bit on the sheet when we are building up the rule 
processors to see if that sheet's rules apply. However, when we disable or 
enable the sheet the rule processors are not rebuilt, so we are still using the 
old rules regardless of the enable-bit. I am testing a change that will rebuild 
the rule processors after a style sheet changes state... stay tuned.

Comment 39

18 years ago
Rebuilding the rule processors when a stylesheet's state changes definitely 
helps! With this change many of the problems of switching between ShowAllTags 
and Normal are eliminated. There are still problems with the images not showing 
up after the first time, however the layout is making room for them. Also, the 
BODY tag image is disappearing when you switch to normal mode now.

The change is simple: added a new method on the nsIStyleSet interface and 
implemented in the StyleSetImpl:

StyleSetImpl::NotifyStyleSheetStateChanged(PRBool aDisabled)
  return NS_OK;

The PresContext has to call this on its mStyleSet member before calling 

PresShell::StyleSheetDisabledStateChanged(nsIDocument *aDocument,
                                          nsIStyleSheet* aStyleSheet,
                                          PRBool aDisabled)
  nsresult rv = NS_OK;

  // first notify the style set that a sheet's state has changed
  if (mStyleSet) {
    rv = mStyleSet->NotifyStyleSheetStateChanged(aDisabled ? 
                                                  PR_FALSE : 
  if (NS_FAILED(rv)) return rv;

  // rebuild the frame-world
  return ReconstructFrames();

(I cannot easily create a patch right how as I have other unrelated changes in 
those files). 

I'm looking into the image problems now.

Charley, I'll be checking in the fix for the Enable/Disable style sheet problem 
as part of a larger nsbeta2+ bug fix - it is clearly wrong and it is easy to fix 
(see related bug 38026). Once I do you can pull it and see that we are now 
correctly handling the icons coming and going, except that the images themselves 
are not always painting (their space is reserved however, and there is even a 
nice little border around where they should be when you select them).

An interesting wrinkle: put some text into the doc, bold, italic, underlines, 
whatever. Switch to Show All Tags - you'll see the icons. Switch back to Normal, 
then back to Show All Tags - no icons now (the problem we have seen for the last 
couple of weeks). Now, select some of the text and change it to a new type, plie 
Heading 4 - voilla, the H4 icons show up. It appears any icon can be used once. 
As I noted before, the layout is leaving room for the icons, they are just not 
being rendered.

I don't think it is a Layout problem. Layout fulfilled its part: the space for 
these images is properly located on the page. We had similar problems (bug 41624 
for instance) with images that don't always appear and they seem to come from 
somewhere between Cache and ImageLib, or maybe History.

The editor images are being marked as IC_INCOMPLETE by the image library when 
they are initially loaded because OnStopRequest() is called and a stream still

So the next time we recreate the image frames, we load the images out of the

it to nsImageRequest which converts it to an IL_ERROR_IMAGE_DATA_TRUNCATED error 
and then calls nsFrameImageLoader::NotifyError(), so the 
nsFrameImageLoader.mImage field never gets set, so there is nothing to paint.

I'm not sure if our gifs are invalid, or if this is a bug in necko.

It looks like nsFileTransport::Process() is firing off an OnStopRequest() in the 
END_READ case. Necko assumes that if a stream exists and an OnStopRequest is 
fired, that an abort is taking place. This is probably the same thing that is 
causing bug #40785 which I just assigned to dougt@netscape.com.
Depends on: 40785
