If a named element (e.g., a flow implementation) has no name the classifier information view throws an NPE and does not display any classifier contents in the right column. An NPE also occurs for unnamed mode transitions.

Expected and Current Behavior

Missing names should be handled:

  • If the name is optional a null name should be interpreted as an empty string (mode transitions)
  • Use the flow specification name for a flow implementation

Steps to Reproduce

  1. Load model below into editor
  2. Select S.i in outline view
  3. Right click > Open in classifier information view
  4. View is empty
  5. Similar for A
package Issue2429
	system S
			i: in feature;
			o: out feature;
			fp: flow path i -> o;
	end S;
	system implementation S.i
			-- NPE when sorting >1 flow implementations
			fp: flow path i -> o;
			fp: flow path i -> o;
	end S.i;
	abstract A
			e: in event port;
			-- NPE when sorting modes and transitions
			-- with unnamed transition
			m1: initial mode;
			m2: mode;
			m1 -[e]-> m2;
	end A;
end Issue2429;
