When an IAccessible alert event is fired, NVDA simply speaks the object and all its descendants. For Mozilla, this means that text can be read multiple times because of Gecko's text leaf nodes. Also, the role of all of the textual content will be read, which is not ideal.

Because alerts already use the IAccessible Dialog NVDAObject, the dialog text (retrieved by getDialogText) is alredy contained in the description property. Therefore, the alert event simply needs to:

  1. Speak the alert object, which will include its dialog text.
  2. Speak all focusable children. This will include all actions available to the user and is necessary because alerts do not receive focus.

I've implemented this in the dialogTextWork bzr branch. Feedback welcome.

(In #160) Now that #277 is fixed, NVDA does not use the virtual buffer at all for objects within an application (which includes dialog and alert dialog). This makes "Dialog 1" in the test case work correctly.

"Alert Dialog 1" still does not work correctly. This is because the OK button is outside the alert dialog node, which is incorrect. The button should be within the dialog in order to be classified as being part of it.

Pending further testing, I believe all of the bugs on our side are fixed.
