[platform-ui-dev] Part notifications broken in HEAD?

[Jared Burns <jaredburns@xxxxxxx>]

I checked out org.eclipse.jface, org.eclipse.ui, and
org.eclipse.ui.workbench from HEAD in order to pick up a new API that
was added to the workbench. But in my testing, I'm not getting any
partClosed() notifications.

Before I file a bug report, I figured I'd check if this is a known
issue. Is there any reason that part notifications wouldn't work in
HEAD?

By debugging, I've verified that my part listener is being registered
with the active workbench page. I've got an existing bug report open for
the fact that *some* part notifications haven't been getting sent
(https://bugs.eclipse.org/bugs/show_bug.cgi?id=50171), but now I'm not
getting any. :(

Thanks for any info,
- Jared
