Closed Bug 616452 Opened 9 years ago Closed 9 years ago
Dynamically inserted select options aren't reflected in accessible tree
STR: 1. With a current nightly build, including the try-server build for bug 498015, file a bug in Core/Disability Access APIs or anywhere you like. 2. Try to request blocking 2.0 on the bug you are filing. Expected: When focusing the combobox and pressing DownArrow, the ? would be selected. Actual: The combobox appears empty. 3. Another instance: Go to http://twitter.com/#inbox and log in with your Twitter account. 4. Try to select an item from the combobox you want to send a direct message to. Expected: An alphabetical list of names should appear. actual: Nothing is selectable. I cannot verify whether this is really empty visually, or if it is just us reporting no entries and no focus change. With FX 3.6, this works fine. Other, more static comboboxes, work fine.
I can confirm this. Visually it is not empty, but this is the sequence of events we get with ff4: object:state-changed:invalid-entry(1, 0, None) source: [combo box | Send a direct message.] object:state-changed:invalid-entry object:state-changed:focused(1, 0, None) source: [combo box | Send a direct message.] object:state-changed:focused and with ff3 it is: focus:(0, 0, None) source: [menu item | acruiz] focus: object:state-changed:focused(1, 0, None) source: [menu item | acruiz] object:state-changed:focused
Fernando, what does "(1, 0, None)" mean?
(In reply to comment #2) > Fernando, what does "(1, 0, None)" mean? That comes from spying at-api events, that is really easy. Here "1" is the detail of the event, that means the focused is true, "0" and "None" are detail2 extra details, that for this kind of event they are going to be always 0 and None
OK. So in the FF4 case the invalid-entry state is becoming true?
The problem here is that dynamically added options are not added to the a11y tree. I'm attaching a mochitest for this.

hacky (didn't think hard), thanks for mochitest
