297069 - Windows opened with |Firefox -chrome myfile.xul| are not accessible

Status: RESOLVED DUPLICATE of bug 241015

(Core :: Disability Access APIs, defect)

Description

[parente]

Application nodes in the MSAA DOM do not always report their children propertly.

For instance, 

firefox -chrome file://c:/parente/mozilla/rdf/resources/dom-test-4.xul

lists it child widgets properly but 

firefox -chrome file://c:/parente/mozilla/rdf/resources/dom-test-8.xul

does not.

For applications that do not list their children, the following exception is 
reported for each child:

* Call to xpconnect wrapped JSObject produced this error:  * [Exception... 
"'Permission denied to get property UnnamedClass.classes' when calling method: 
[nsIAccessibleProvider::accessible]"  nsresult: "0x8057001e 
(NS_ERROR_XPC_JS_THREW_STRING)"  location: "<unknown>"  data: no]

The exception is happening at:

http://lxr.mozilla.org/seamonkey/source/accessible/src/base/
nsAccessibilityService.cpp#1846

Comment 2

This bug appears to be happening for all XUL child widgets of an application or 
dialog node run as a standalone.

[Aaron Leventhal]

The exception is the big clue.

Apparently we're running the chrome with the permissions of content, so it
doesn't have the security privileges necessary to create an accessible.

Similar to bug 241015. Probably the same fix.

I'm sure it's a dupe of bug 241015. If it isn't please feel free to reopen bug.
