> Hi, Rich. I missed what kind of problem here. I *think* the problem is that 90, 91, and 92 are testing a "selection follows focus" scenario. However, as Rich noted, nothing in the test file changes the focus -- that's why these test files are invalid. But, if the test file was modified such that focus did change, what is observed in terms of events? Using test case 91 as an example: the setup is a multiselectable list with two options with no option selected. At a certain point in time, focus moves to the second option. Consequently, according to the "selection follows focus" model, the second option is also marked aria-selected="true". According to the UAIG, for selection follows focus, under MSAA+IA2: "EVENT_OBJECT_SELECTION and EVENT_OBJECT_STATECHANGE on newly focused item, but arrange events so state change does not occur on focused item, to avoid extra selection change announcements". However, Rich is observing: > ... both the state change and the selection change occurs on that element. -- ;;;;joseph. 'A: After all, it isn't rocket science.' 'K: Right.
