390629 - ARIA trees not providing state EXPANDABLE

Status: RESOLVED FIXED

(Core :: Disability Access APIs, defect)

Description

[Scott Haeger]

The ARIA tree shown here http://archive.dojotoolkit.org/nightly/dojotoolkit/dijit/tests/test_Tree.html is not providing state EXPANDABLE for branches that are expandable.  They are however providing state EXPANDED and an object:state-changed:expanded event.

Does this one work?

I think maybe they forgot to put aaa:expanded="false" on the ones that are potentially expandable. It's different from leaving aaa:expanded out entirely.

Simon, can you look at comment 1 and let us know if that's the problem?

Same results as dojo tree.

Attachment: Get ARIA state before computing EXPANDABLE!

Yep, that's a legit bug! Nice catch!

We didn't see that in MSAA because there is no EXPANDABLE state there.

Right. Some time before I thought to do myself but I didn't know usecase :).
