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
