I been intending to do this for a while now.static labels is kinda weak.
Anyway, is your Label a figure or an editpart? If you want to drag it
around seperately from the connectioneditPart then it will need to be
inside its own editpart. That will be my strategy anyway.

Ahh, so you have an editpart that contains your Label, and that
LabelEditPart is the child of the ConnectionEditPart which in turn is a
child of the DiagramEditPart.
Great, thats what I planned to do.
As to your direct situation. Is your DiagramEditPart your drawing so to
speak? and your ConnectionEditPart is ontop of that?
I'm surprised its not working. I Can only imagine your problem is that
your LabelEditPart is not returning a command for the move request. Set
a breakpoint in the LabelEditParts getCommand(Request) method and see
why its not returning an appropriate command. Im my experience, unless
you specifically do something to stop it, the childmost editpart gets
first shot at the command. As long as it is still returning true for
isSelectable() since move first requires selection.
Make sure your LAYOUT_ROLE edit policy is creating a command to move
this child too. I am speaking of the policy in the ConnectionEditPart
since its containing the Label.
