DNDAddon Trouble [message #915395]

Hi! I am currently playing around with eclipse 4.2 to get a feeling how much effort it would be to port our current 3.7 RCP Application to Juno. I ran into some strange behaviour of the DNDAddon and just wanted to know if this is a bug or if i am doing something wrong.

I have a plain Application Model with just a

Trimmed Window
-> Perspective Stack
--> Perspective
---> Part Stack (which is empty)

Now i add via a MenuItem new Parts to the Part Stack dynamically which works fine (got the source from lars vogels tutorial [not allowed to paste the link]).

When i enable DnD via the DragAndDrop- and the CleanUp-Addon also everything works fine as long as i keep one Part in the Part Stack. I can drag and drop the rest of my Parts where ever i want.
Now my Problem is when i move the last Part remaining in the Main-Window (so that this window would be empty) out of it. The new "part-Window" and all the others disapear and as i can see in the live-editor also the Part Stack is gone. This also happens if i only create one part and drag it out.

Maybe somebody has some advice what i am doing wrong or if this is a bug.
Thx in advance and
regards weinma

The problem is that by default Stacks are collapsed if there's no child
anymore (the only exception in 3.x was the editor stack in this respect)
and the cleanup addon is present (well in fact that's its sole job).

If you don't want the stack to collapse you can tag it with
IPresentationEngine.NO_AUTO_COLLAPSE and it will stay as an empty one.

Hey!
Thanks a lot.. Now the partStack stays if i just close the tab.
But it doesn't solve the problem that all the windows(parts) that i dragged out of the main window disappear (also the partStack again) when i move the last tab(part) out of the main window.

best regards
weinma
