I am dragging a node of a Tree Table onto another node of the same Tree Table. The drop should open a window. Although the drag and the drop were successful, Jubula stunted on WaitForWindow. The dragged object was not shown in Jubula but well if I am doing the same operation by hand. Is it normal?
[Just in case it could help: The called window is an org.eclipse.jface.dialogs.MessageDialog using the MessageDialog.openConfirm method via a ViewerDropAdapter]
You should indeed see that the node was dragged and dropped - from your screenshots it looks like the drag and drop does not actually happen. I wonder whether this has anything to do with the tree being a tree table - are you able to drag and drop on plain trees?
Reading your last post I realized that you've been recording the steps - have you tried manually specifying the drag and drop actions? (If you've not done manual specification before, I'd recommend doing the cheat sheets from the help menu - start with the "First Steps" one). It could be the case that the recording of these actions isn't totally supported.
In fact, the recording does not work. Thus I used the manual test cases (tried several ones). All failed on this table tree. I tried with simpler (SWT) trees and here too the recording failed but the manual test cases worked.
It might be worth putting an issue into bugzilla for this then (the fact that drag and drop does not work on tree tables). If your developers can provide a small example AUT to exemplify the problem, that would make finding the cause much easier, I think.
