    Default Grid Header ContextMenu disappear after column move

    Grid Header ContextMenu disappear after column move


    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:
    Code:
    /**
     * 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.
    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);
          }
    
        }
