Hello!
I have a 2 EditParts. One is a container for the other. I have overriden =
the container's "getDragTracker()" method to obtain a =
"move-to-click-location" behavior for the child part. All works well, =
the child part moves where I click on the parent, I can select the child =
part, everything is ok.
Now I want to do some improvement to the container's figure, so I add a =
Label to it's figure and surprise: I still have the =
"move-to-click-location" behavior but I can't select the child part as =
if the Label is blocking access to it. Why is this happening and how =
should I get arround it?
Thank you!

Hi,
it seems that you have not have installed the appropriate Policy at =
container's or childs EditPart, which should return something like =
ChangeBoundsCommand.
if you are extending for example =
org.eclipse.gef.editpolicies.XYLayoutEditPolicy.
protected Command createChangeConstraintCommand(EditPart child,
Object constraint) {
// HERE CREATE COMMAND.
// This command have to do in execute method change model bounds, =
and than it is refreshed by notification mechanism.
return CMD;
}
Best Regards,
John Cage
