Well, I have

new CallflowSelectionEditPolicy());

Try to see what is req anyway?
What type do You get?

Hope that helps, Greg

I'm not sure if DragTrackers are used in the tree since reordering is done
using native drag-and-drop.
Are you returning the drag tracker in the tree editpart? BTW, pick one
place/thread to discuss this problem.

Thank you for your reply.
I tried that and did get breakpoint in SelectionEditPolicy.showSelection()
if a node was selected. But still can't to handle double-click because still
no REQ_OPEN and REQ_SELECTION found in performRequest(Request req).
Actually I didn't find any request. But I don't think it's because
EditPolicies were not installed. In another view of my program, there is no
editpolicy handling REQ_OPEN, either, but I got REQ_OPEN in that editpart's
performRequest(). Is it because the outline TreeViewer has handled many
requests so that it doesn't dispatch them?
Thanks,
Miaohua Xu

Thank you for your reply!
I am guessing the outline TreeViewer has handled such request so that it
doesn't dispatch them. Could you please point out a direction for me? Say,
shall I look into the source code of treeViewer? or something else?
Additional, what do you mean by saying "pick one place/thread to discuss
this problem"? I am kind of new to Eclipse.
Thanks!

You should be looking at the editpart's getDragTrackerMethod, and at
SelectEditPartTracker, which is the tool that sends the open request. You'll
note that AbstractTreeEditPart does return a drag tracker, so this request
never gets sent.
Please open a bug for a special drag tracker just for treeitems which only
sends these requests, but doesn't perform any selection

I am referring to the different places on this newsgroup that you are asking
about the same problem
