Description Peter Lam 2008-09-06 00:50:44 UTC 
build 20080905

DnD the sequence diagram node to another sequence diagram is not allowed. However, Ctrl+Enter on the sequence diagram
node to another diagram throws the following exception. See attached ide log file for complete exception.
Ctrl+Enter on any other diagram node trying to add to the sequence diagram will also result in this exception.

Comment 3 Thuy.d Nguyen 2008-09-08 19:10:22 UTC 
This issue does not occur to other diagram types, because for other diagram types DefaultDiagramEngine::processDrop
method just returns the dropElement itself and the element is later checked for null in the
DiagramInputkeyAction::processModelTreeNodes method before it is further processed.
Comment 4 Peter Lam 2008-09-08 19:30:29 UTC 
verified in build 20080908 on all diagram types to sequence diagram.
