Hi, dear all
I'm extending an existing GMF editor and add drag&drop behavior to that
editor.
I've successfully created and installed editpolicy to provide the
drag&drop behavior. And when user of the diagram editor drop a object
into the diagram, I need to create and config a new node and
corresponding semantic element in the diagram.
So I created a CreateViewAndElementRequest and using
editpart.getCommand(createRequest) to get corresponding command. If I
use this Command object as return value of
DragDropEditPolicy.getDropObjectsCommand(), the diagram node and
semantic element are created correctly.
The problem is I hope to config the newly created object immediately
after it got created. I guess it might need a CompositeCommand which
contains two commands:
1. Command object from getCommand() function.
2. A new kind of Command object to config the newly created object
The problem is how to get the newly created objects in the 2nd Command
object.
Any suggestions are welcome!

Hi James,
I don't know if you have already solve your problem...
I think but I'm not sure that you can use the "chain" method in your
command object. hope that will help you...
I'm interesting in your getDropObjectsCommand() method, could you please
send it?
