NullPointerException case

[ashouric]

Dear all,

The following test case gives a NPE, it is extracted from a realtime working version.

Code: Select all

public class Test extends Composite implements ClickListener {

   private FlexTable mainTable;
   private Label priorityL;

   public Test() {

      final DockPanel dockPanel = new DockPanel();
      initWidget(dockPanel);

      mainTable = new FlexTable();

      priorityL = new Label("Priority");
      mainTable.setWidget(0, 0, priorityL);

      final VerticalPanel verticalPanel = new VerticalPanel();
      verticalPanel.add( mainTable );
      dockPanel.add(verticalPanel, DockPanel.CENTER);
   }

   public void onClick(Widget sender) {
      int row = mainTable.getRowCount();
      mainTable.insertRow( row );
      mainTable.setWidget( row, 0, new Label() );
   }


}

Use a code hiding tag to hide the following line...

Code: Select all

mainTable.setWidget(row, 0, new Label()); //$hide$

In the latest build, Designer should be able to parse the original example code without any mods.

That's great, although hiding is a valid solution, this tolerates the annoying Exception.

Many thanks.
