I just updated to JavaFX 2.1 b19 and noticed that double click in my TreeCells doesn't work anymore.

It used to work in prior versions (last version I had was b13).

As this is quite important for us, is it possible to get fixed for 2.1 GA ?

EDIT:
After some deeper investigation, I figured out, the problem only occurs, when the TreeView is within a Tab control. My first thought, was that maybe the Tab control consumes some mouseevents, but double clicking on a TextField still works within a tab.

Here is some sample code. Double-click the TreeItem ("String1") with left mouse key. No output. Double-click it with right mouse key: output!
Put the treeview out of the tab and as a direct child of root: Double-clicking works again for both mouse keys.

If you can't fix it for 2.1, is there a workaround?
