Comment 1 Patrick Tessier CLA 2010-07-06 08:47:28 EDT 
This bug comes from  EditorUtils.getTransactionalEditingDomain() . It access to papyrus by looking for the active editor.
So EditorUtils.getTransactionalEditingDomain() return null and cannot execute command during the creation of the editor with this diagram
So I have open a test in order to test it.
thet no anymore null point exception
