Grid Header ContextMenu disappear after column move

[terciofilho]

Hi!

I use a ContextMenu in Grid's Header.

After que Column Reorder in Grid the ContextMenu doesn't show up again.

Procedure: Run the the test-case, right-click the column header, reorder the column and try to show the context menu again.

Test-Case:

/**
 * Entry point classes define <code>onModuleLoad()</code>.
 */
public class GxtTest implements EntryPoint {

	/**
	 * This is the entry point method.
	 */
	public void onModuleLoad() {
		RootPanel rootPanel = RootPanel.get();
		LayoutContainer cont = new GridExample();
		rootPanel.add(cont);
	}

	class GridExample extends LayoutContainer {

		private ColumnModel cm;

		@Override
		protected void onRender(Element parent, int index) {
			super.onRender(parent, index);
			setLayout(new FlowLayout(10));
			getAriaSupport().setPresentation(true);

			List<ColumnConfig> configs = new ArrayList<ColumnConfig>();

			ColumnConfig column = new ColumnConfig();
			column.setId("name");
			column.setHeader("Company");
			column.setWidth(200);
			column.setRowHeader(true);
			configs.add(column);

			column = new ColumnConfig();
			column.setId("symbol");
			column.setHeader("Symbol");
			column.setWidth(100);
			configs.add(column);

			ListStore<Stock> store = new ListStore<Stock>();
			store.add(TestData.getStocks());

			cm = new ColumnModel(configs);

			ContentPanel cp = new ContentPanel();
			cp.setBodyBorder(true);
			cp.setHeading("Basic Grid");
			cp.setButtonAlign(HorizontalAlignment.CENTER);
			cp.setLayout(new FitLayout());
			cp.getHeader().setIconAltText("Grid Icon");
			cp.setSize(300, 300);

			final Grid<Stock> grid = new Grid<Stock>(store, cm);
			grid.setAutoExpandColumn("name");
			grid.setBorders(false);
			grid.setStripeRows(true);
			grid.setColumnLines(true);
			grid.setColumnReordering(true);
			cp.add(grid);

			grid.addListener(Events.Attach, new Listener<BaseEvent>() {
				@Override
				public void handleEvent(BaseEvent be) {
					Menu contextMenu = new Menu();
					contextMenu.add(new MenuItem("ContextMenu Option"));
					grid.getView().getHeader().setContextMenu(contextMenu);
				}
			});

			add(cp);
		}

	}

	@SuppressWarnings("serial")
	public static class Stock extends BaseModelData {
	}

	static class TestData {

		public static List<Stock> getStocks() {

			List<Stock> stockList = new ArrayList<Stock>();
			Stock stock1 = new Stock();
			stock1.set("name", "name");
			stock1.set("symbol", "symbol");
			stock1.set("date", new Date());
			stockList.add(stock1);

			return stockList;
		}

	}
}

This is not a bug. The issue is in your code.

 class GridExample extends LayoutContainer {

      private ColumnModel cm;

      @Override
      protected void onRender(Element parent, int index) {
        super.onRender(parent, index);
        setLayout(new FlowLayout(10));
        getAriaSupport().setPresentation(true);

        List<ColumnConfig> configs = new ArrayList<ColumnConfig>();

        ColumnConfig column = new ColumnConfig();
        column.setId("name");
        column.setHeader("Company");
        column.setWidth(200);
        column.setRowHeader(true);
        configs.add(column);

        column = new ColumnConfig();
        column.setId("symbol");
        column.setHeader("Symbol");
        column.setWidth(100);
        configs.add(column);

        ListStore<Stock> store = new ListStore<Stock>();
        store.add(getStocks());

        cm = new ColumnModel(configs);

        ContentPanel cp = new ContentPanel();
        cp.setBodyBorder(true);
        cp.setHeading("Basic Grid");
        cp.setButtonAlign(HorizontalAlignment.CENTER);
        cp.setLayout(new FitLayout());
        cp.getHeader().setIconAltText("Grid Icon");
        cp.setSize(300, 300);

        final Grid<Stock> grid = new Grid<Stock>(store, cm);
        grid.setAutoExpandColumn("name");
        grid.setBorders(false);
        grid.setStripeRows(true);
        grid.setView(new GridView(){
          @Override
          protected ColumnHeader newColumnHeader() {
            
            ColumnHeader h= super.newColumnHeader();
            Menu contextMenu = new Menu();
            contextMenu.add(new MenuItem("ContextMenu Option"));
            h.setContextMenu(contextMenu);
            return h;
            
          }
        });
        grid.setColumnLines(true);
        grid.setColumnReordering(true);
        cp.add(grid);

     

        add(cp);
      }

    }
