This new widget is a bit like a dropdown tree view. Currently the widget is in Thunderbird. Unfortunately, as you arrow through it, the items are not spoken by either Window-Eyes or JAWS. I see MSAA focus events generated for ROLE_OUTLINEITEMs, but perhaps the issue relates to the parent accessible. Would need to investigate

Presumably the accessibility code isn't expecting a tree in a menulist?

Since the widget isn't used in Firefox, I don't feel comfortable blocking on this platform sec508 problem. That said, I *do* think it should be fixed, so we should be willing to accept a patch on this all the way up to RC1.

tb1.5.0.x and trunk nightly works fine.

(In reply to comment #3) > tb1.5.0.x and trunk nightly works fine. ... for Linux. Still broken on Windows.

The folder picker definition is somewhere around here: http://lxr.mozilla.org/seamonkey/source/mailnews/base/resources/content/mailWidgets.xml#1712 I think it would need a new nsIAccessibleProvider implementation, and expose itself as a tree.

xref bug 315367, bug 350962.

Is this bug still valid? If I right-click on a message in Thunderbird Trunk, and select the Copy To/Move To sub menus, I see all folders as regular menu items and can access them. Is this folder picker something else, or has the folder picker become this sub menu structure? if the former: How do I get to it? If the latter, this bug may have resolved itself.

I believe the widget exists in three places in Thunderbird: 1) As an optional toolbar element 2) As a Move/Copy to filter action 3) As the advanced search folder

Thanks Neil! I've been able to find the widget in the Find Messages... dialog. And it works fine there using both JAWS 8.0 and Orca 2.20 on Windows and Linux respectively.

worksforme?

Marco, please try it in Window-Eyes. If it works there, then WORKSFORME.
