How is that other element related? How will you locate that other
resource? Do you plan to load that resource into your editor's resource
set and save it and with the other resources in the editor's resource
set when the editor saves?

Hi Ed,

i have 2 diagram. On first diagram when i create web element i must create SitePermission element on another diagram and then on web element i must set releation to SitePermission element. I done this with your help (http://www.eclipse.org/forums/index.php/m/1073620/#msg_1073620).
(I load second resource to first resource resourceset and when i hit save from diagram all resources being saved)
There is no problem

Now i need when i delete web element from first diagram i must delete referanced SitePermission element from second diagram.

But i dont know where is the delete action of elements or commands.
So i want to ask u how can i add this behavior to my first diagram?

Regards.
