Will not it be fixed?

Severity: normal → major

Enrique, this will get fixed. However this is not trivial to fix and there is more important issues to work on. This can be worked around by un-@importing the style sheets (using multiple <link> or <style>) on a web page you're working on.

Got bitten by that today. I can't analyze a page without that. (I do not control the content)
Attached patch Fix, part 1 (obsolete) — Splinter Review
This fix part 1 adds 1. visibility of all nested levels of imported stylesheets 2. application of changes in imported stylesheets 3. modification of styleSheetIndex to correctly handle all stylesheets Part 2 will focus on what happens when an stylesheet's import is added to or removed from a parent stylesheet.
I've revived the patch from comment #5, cleaned it up a bit, and added a test. This enables you to see and edit stylesheets loaded via @import rules. If this looks good, I'll start looking into further changes for dynamically added @imports.

Comment on attachment 720516 [details] [diff] [review] Patch v2 I'll take a look at this too.

Comment on attachment 720516 [details] [diff] [review] Patch v2 Great to see @import working. Thank you for the patch! Just one issue: I am not seeing any styles at on this page: http://mihaisucan.github.com/mozilla-work/test.html Do you know why? I would like to apologize for the time it took me to get to your patch. Lots of stuff in my queue. Please also Heather in the feedback and review process. She is working on style editor improvements, if I am not mistaken. I do not know how this patch fits with the work she is doing. I am currently involved in other developer tools projects. Heather, thank you for taking this patch in your review queue.

Comment on attachment 720516 [details] [diff] [review] Patch v2 Review of attachment 720516 [details] [diff] [review]: ----------------------------------------------------------------- Thanks so much for the patch. As for the site that Mihai pointed out, when you open the style editor this error appears in the Error Console: Error: TypeError: aSheet is null Source File: resource:///modules/devtools/StyleEditorChrome.jsm Line: 297 So we'll need to fix that. I'm currently rewriting the style editor to do remote debugging, but that won't land for a couple more weeks. If we get this in in the meantime, and I can just incorporate your code before I land. ::: browser/devtools/styleeditor/StyleEditor.jsm @@ +136,5 @@ > + if (this._styleSheetIndex != -1) > + return index; > + } else if (rule.type != Ci.nsIDOMCSSRule.CHARSET_RULE) { > + // @import rules must precede all others except @charset > + return index; nice ::: browser/devtools/styleeditor/test/browser_styleeditor_import_rule.js @@ +19,5 @@ > +function run(aChrome) > +{ > + is(aChrome.editors.length, 3, > + "there are 3 stylesheets after loading @imports"); > + Might as well make sure it's the correct style sheet while you're at it.

Attached patch Patch v3 (obsolete) — Splinter Review
This patch should be ready to go. Dynamically added style sheets are not yet handled though. My preference would be to defer that and file a separate bug to resolve it, but let me know if you feel it belongs here instead.

Mihai's test page had an @import cycle (A imports B imports A), which results in the styleSheet property being null once when you visit the same one again further down the chain. I'm checking for this case now, and Mihai's test site now shows all relevant CSS files. > ::: browser/devtools/styleeditor/test/browser_styleeditor_import_rule.js > @@ +19,5 @@ > > +function run(aChrome) > > +{ > > + is(aChrome.editors.length, 3, > > + "there are 3 stylesheets after loading @imports"); > > + > > Might as well make sure it's the correct style sheet while you're at it. > Good to be safe. Added these tests. I've also changed the test case to be an import cycle like Mihai's site.

Comment on attachment 723567 [details] [diff] [review] Patch v3 Review of attachment 723567 [details] [diff] [review]: ----------------------------------------------------------------- Sorry for the delay, this looks good.

I am no longer able to reproduce this issue with the latest code in fx-team, so it look like no bug is needed. Sorry I forgot to update this issue about it, and thanks for double checking! :)
