Status: VERIFIED FIXED

(Core :: Disability Access APIs, defect)

In both Thunderbird3 and Firefox3 options dialogs, the list of tabs contains items that all have an IAccessible role of list. Usually it would be expected that these be list items. I *think* these have an XUL tag of "radio" according to the IAccessible2 tag object attribute. From a quick look at nsRoleMap.h, I can see that ROLE_RICH_OPTION is mapped to ROLE_SYSTEM_LIST. I'm not sure if this is the problematic amapping or not? but reading the description of ROLE_RICH_OPTION it says its an option that could contain children. However, I would still think that mapping this to listItem would be more appropriate, as all the exampls I've seen (if this is in deed the problem) they only contain a label as a child, not much else.


Reproducible: Always

Steps to Reproduce:
1. Open Firefox3 or Thunderbird3
2. Open the options dialog
3. Using Accessibility Probe, locate the Options dialog frame.
4. Open this branch, one of the child branches should be a list
5. Open the list's branch
6. notice the list's children
Actual Results:  
The list's children all have a role of list. Also using the properties view of Accessibility probe, you can see the IAccessible2 object attributes contain tag:radio

Expected Results:  
The children should either have a role of listItem, or radioButton, but not list.

This will get changed with the fix for bug 407359. That bug will reclass the RichOption to an ListItem instead of a List.
