Shortcuts working but not drag-drop [message #483579]

Hello all,

In my project, I have configured shortcut functionality between
different editors sharing the same model. The shortcut functionlity
works without a problem but I am not able to execute the same process
using drag-drop functionality.

In other words, i cannot drag elements from the "Project Explorer" to my
diagram.I have read older posts and have not found a similar issue.

On debugging I have come across the following issues :
1. The getObjectsBeingDroppe() method In my **DiagramEditor gives back
the correct object
2. The corresponding isEnabled() method in the DiagramDropTargetListener
checks if the Compound commands could be executed or not.
In this
List(ToggleCanonicalModeCommand,Command$1$ChainedCompoundCom mand,ToggleCanonicalModeCommand)

Command$1$ChainedCompoundCommand always return false and I think that
the drop is not executed because of this....

can someone give me a clue as to what could be wrong with my
configuration or where I could start towards a solution

thx
Jan Red

Hello Jan,

Do you have DiagramDragDropEditPolicy installed with DRAG_DROP_ROLE in ???EditPart
generated for the diagram? I think the command you are talking about came
from there, so you can put a reakpoint there to see the reason..
