Cum se rezolva aceasta eroare ?

error: incompatible types: java.util.List cannot be converted to java.awt.List
                graph.setSelectionCells(graph.getSelectionCellsForChanges(changes));

final mxEventSource.mxIEventListener selectionHandler = new mxEventSource.mxIEventListener() {
            public void invoke(final Object source, final mxEventObject evt) {
                final List changes = ((mxUndoableEdit)evt.getArgAt(0)).getChanges();
                graph.setSelectionCells(graph.getSelectionCellsForChanges(changes));
            }
        };

Daca pun import java.uitl.list eroarea imi apare pe ultimul rand din cod. Daca pun java.awt.List eroarea apare pe penultimul rand. De fiecare data e la fel ca nu se pot schimba tipurile ba unul, ba celalalt. Nu reusesc sa rezolv problema. Sunt incepator la Java, va rog ajutor.

 

Multumesc mult !

E prea vag codul pe care l-ai pus dar pot presupune ca setSelectionCells cere awt.List ca parametru insa tu ii dai utils.List.

Daca amandoua implementeaza IList faci cast;

 

final List changes = ((mxUndoableEdit)evt.getArgAt(0)).getChanges();

graph.setSelectionCells((awt.List)graph.getSelectionCellsForChanges(changes)));

 

.. daca nu atunci initializezi variabila 'changes' ca obiect de tip awt.List;

Am rezolvat exact asa cum ai spus tu.
