Hello,
This is my case. I want to modify the "flow" example of GEF3.0 to implement
functions that can expand/collapse the StructuredActivityEditPart by
double-click or ContextMenu.
Here is my step:
1.add the attribute named "isExpand" on the StructuredActivity Model;
2.add the command "ControlUnfoldCommand" to control the model's attribute;
3.add the EditPolicy to get that command,then install that EditPolicy
mapping DIRECT_EDIT_ROLE;
How should I do next ?

Override performRequest() in your EditPart to launch the direct edit
manager. If you're not sure how to do this, look at our several examples or
just search this newsgroup.

Lastly, when your command changes the model, your EditPart will be notified
of this change. At that point, you'll have to update your figure to look
like it's expanded/collapsed.
