LiveGridView - NullPointerException

Description
I'm using a LiveGridView without a Loader, and that leads to a NullPointerException:

Caused by: java.lang.NullPointerException: null
at com.sencha.gxt.widget.core.client.grid.LiveGridView.initData(LiveGridView.java:361)
at com.sencha.gxt.widget.core.client.grid.GridView.init(GridView.java:1854)
at com.sencha.gxt.widget.core.client.grid.Grid.onAttach(Grid.java:957)

You're not checking whether the loader is null and try to add a LoadHandler to that (non-existent) loader.

Test case

public class MyGrid extends Grid
{
    static TestProvider prov = GWT.create(TestProvider.class);

    public MyGrid()
    {
        super(new ListStore<TestDTO>(prov.oid()), new ColumnModel(getColumnConfigList()),
                new LiveGridView<TestDTO>());

        setBorders(true);
        getView().setColumnLines(true);
        getStore().add(new TestDTO(1, 3, 1));
        getStore().add(new TestDTO(2, 4, 2));
        getStore().add(new TestDTO(3, 9, 6));
        getStore().add(new TestDTO(4, 7, 2));
    }

    private static List<ColumnConfig> getColumnConfigList()
    {
        List<ColumnConfig> columnConfigList = new ArrayList<ColumnConfig>();
        columnConfigList.add(new ColumnConfig(prov.att1(), 250, "Column 1"));
        columnConfigList.add(new ColumnConfig(prov.att2(), 250, "Column 2"));

        return columnConfigList;
    }

    class TestDTO
    {
        private int oid;
        private int att1;
        private int att2;

        public TestDTO(int oid, int att1, int att2)
        {
            super();
            this.oid = oid;
            this.att1 = att1;
            this.att2 = att2;
        }

        public int getAtt1()
        {
            return att1;
        }

        public void setAtt1(int att1)
        {
            this.att1 = att1;
        }

        public int getAtt2()
        {
            return att2;
        }

        public void setAtt2(int att2)
        {
            this.att2 = att2;
        }

        public int getOid()
        {
            return oid;
        }

        public void setOid(int oid)
        {
            this.oid = oid;
        }
    }

    interface TestProvider extends PropertyAccess<TestDTO>
    {

        ModelKeyProvider<TestDTO> oid();

        ValueProvider<TestDTO, Integer> att1();

        ValueProvider<TestDTO, Integer> att2();
    }

}

Currently LiveGridView always requires a Loader. You could simple use a MemoryProxy for now that serves local data too. I am closing this thread for now, but keeping it on the list as a feature request.
