Hello,
While dragging an item picked from the canvas over a connection, I see that
CompoundCommand is created. This command contains two commands
OrphanChildCommand and UnexecutableCommand. The former is required to remove
an object being dragged from its parent. The latter prevents the whole
CompoundCommand to be executed.
1. I don't know who puts the UnexecutableCommand into CompoundCommand - is
it DragEditPartsTracker? Just curious.
2. I cannot replace UnexecutableCommand by AddCommand. I add
(COMPONENT_ROLE, MyXYLaoutPolicy) for the Connection's part, however its
createAddCommand is ignored, and CompoundCommand still contains
UnexecutableCommand.
Where do I go wrong?
Thanks.
Vladimir

It looks like you don't have a target editpart.
DragEditPartsTracker is excluding the entire connection layer. This was
done to avoid connections from getting in the way of the real targets.
Override the methods which prevent htat layer from being targeted. Open a
bugzilla if you think this needs to be customizable in GEF.
