Description Joanmarie Diggs 2015-12-14 18:33:52 UTC
Steps to reproduce:
1. Launch LibreOffice Writer
2. Launch Accerciser and enable monitoring for LO children-changed events
3. Create several new paragraphs
4. Delete the paragraphs

Expected results: object:children-changed events would be logged by Accerciser.

Actual results: No object:children-changed events are logged by Accerciser.

In addition: Currently LO Writer exposes only on-screen paragraphs to ATs. As a result, when switching pages, the accessible tree is updated so that the document's children are the visible paragraphs. In other words, children are being added and removed. However, there are no object:children-changed events seen as a result.

In Accerciser, I selected soffice and then in Event monitor, radio button Selected application. Under Object, I ticked children-changed.

I do not reproduce the problem. I do get log events for children changed.

Please retest.

Change back to UNCONFIRMED, if the problem persists. Change to RESOLVED WORKSFORME, if the problem went away.

I'm doing what you're doing. And I continue to not see children-changed events. I tried with both and

Mind you I get children-changed events from soffice. For instance, if I open a menu. But what I am not getting is children-changed events when I type text and press return (creating new accessible paragraph objects).

I tried it again and I guess I was confused.
