79313 - editorShell ApplyStyleSheet does not work for jar resource

Status: VERIFIED INVALID

(Core :: DOM: Editor, defect)

Description

[Peter Wilson]

When I run an XUL app from unzipped files the following line works correctly:
 
editorShell.ApplyStyleSheet("chrome://xulapp/content/JSsyntax.css");

If I zip these same file into a jar and install the application I get the 
following error from the above line:

Error: [Exception... "Component returned failure code: 0x80520006 
[nsIEditorShell.ApplyStyleSheet]"  nsresult: "0x80520006 (<unknown>)"  location: 
"JS frame :: chrome://xulapp/content/JSEditor.js :: anonymous :: line 41"  data: 
no]
Source File: chrome://xulapp/content/JSEditor.js
Line: 41

hrm, so is this a bug in Editor or Chrome? [Chrome?]

I don't see how it can be an editor bug. We are using very standard APIs for
loading CSS files. It seems to me it shouldn't matter whether it's in a jar or
not, but I'm not the one who would know that.

Um, this may not be it, but your style sheet filename is mixed case. A mismatch
won't matter on a win32 filesystem, but will matter when looked up in a jar
file. So, if the filename is 'jsstatus.css' it won't be found, and hence, won't 
be applied.

If not, need a full, preferably simple, example.

I think Editor should actually own this, at least as far as pointing out where
the editor shell fails and why.

Er, to be clear, if it's a case mismatch, then this bug is INVALID.

The call to applyStyleSheet in my code does indeed contains a different 
capitalization than the file name. I was unaware of this feature in jar files. 
Pilot error.
