How did you invoke branch deletion (Repositories View, History View, team menu) ?

I attempted the deletion both from the "Switch to..." item in the right-click popup menu in repositories view and also from the 'Checkout Branch etc' toolbar item. Either way I ended up in the Branches dialog.

Just now I successfully deleted a branch in Juno by navigating to it in the repositories view and using the "Delete" entry in the right-click popup. I also deleted successfully from history.

So looks like it's just the delete operation in the Branches dialog that's broken in Juno.

Am I the only person seeing this problem? Is it maybe platform-specific (I'm on OS X)? How could an operation as basic as branch deletion be left broken for so long?

Yes, I know I can do it by switching to the Git Repositories view, or for that matter to a shell. But I'm always in the primary development perspective (Java, C++, etc) when I want to delete a branch and the whole point of integration is not having to switch context.

I just tried it on windows and had the same problem. However, the real cause seems to be another exception (NPE). I attached that to the bug.

Right, the exception's cause is

org.eclipse.egit.ui.internal.repository.tree.command.RemoveCommand.removeRepository(RemoveCommand.java:78)
at org.eclipse.egit.ui.internal.repository.tree.command.DeleteCommand.execute(DeleteCommand.java:22)
at org.eclipse.ui.internal.handlers.HandlerProxy.execute(HandlerProxy.java:293)
at org.eclipse.ui.internal.handlers.E4HandlerProxy.execute(E4HandlerProxy.java:76)

Looks like I missed the end of the error log when I pasted into the bug report I filed a few weeks ago. Sorry about that.

Problem seems to be fixed in Juno SR1 + EGit 2.2.0.201209272213. Whether the fix came from SR1 or from the nightly build of EGit, or some combination, I don't know.

AFAIK the fix was in Eclipse itself.
