List Grid multilevel sorting problem

[mayankrjain]

Hi,

I want to use multilevel sorting in ListGrid. I am writing following code for this but while running application and clicking on MultiLevel Sort button I am getting this exception. Please help me for this.

code:

positionGrid.setCanMultiSort(true);
positionGrid.setDataSource(DataSource.get("positionView"));

IButton sortButton = new IButton("Multilevel Sort");
sortButton.setWidth(120);
sortButton.addClickHandler(new ClickHandler() {
public void onClick(ClickEvent event) {

try {
MultiSortDialog.askForSort(positionGrid, positionGrid.getSort(), new MultiSortCallback() {

@Override
public void execute(SortSpecifier[] sortLevels) {
if(sortLevels != null) {
positionGrid.setSort(sortLevels);
}

}
});
} catch (Exception e) {
e.printStackTrace();
}
}
});

Exception:
com.google.gwt.core.client.JavaScriptException: (TypeError): self.getSort is not a function

This is working for us. Here's our complete test case.
Can you verify you're running against the latest nightly build?

	public void onModuleLoad() {

		final ListGrid positionGrid = new ListGrid();
		DataSource pView = new DataSource();
		pView.setClientOnly(true);
		pView.setID("positionView");
		
		DataSourceField f1= new DataSourceField("f1", FieldType.INTEGER);
		DataSourceField f2 = new DataSourceField("f2", FieldType.INTEGER);
		pView.setFields(f1,f2);
		
		ListGridRecord r1 = new ListGridRecord();
		r1.setAttribute("f1", 0);
		r1.setAttribute("f2", 100);
		
		ListGridRecord r2 = new ListGridRecord();
		r2.setAttribute("f1", 100);
		r2.setAttribute("f2", 0);
		
		ListGridRecord r3 = new ListGridRecord();
		r3.setAttribute("f1", 100);
		r3.setAttribute("f2", 100);
		
		Record[] testD = new Record[] {r1,r2,r3};
		
		pView.setTestData(testD);
		
		positionGrid.setCanMultiSort(true);
		positionGrid.setDataSource(pView);
		positionGrid.setAutoFetchData(true);
		
		IButton sortButton = new IButton("Multilevel Sort");
		sortButton.setWidth(120);
		sortButton.addClickHandler(new ClickHandler() {
		public void onClick(ClickEvent event) {

		try {
			MultiSortDialog.askForSort(positionGrid, positionGrid.getSort(), new MultiSortCallback() {
	
				@Override
				public void execute(SortSpecifier[] sortLevels) {
					if(sortLevels != null) {
						positionGrid.setSort(sortLevels);
					}
		
				}
			});
		} catch (Exception e) {
			e.printStackTrace();
		}
		}
		});
		
		VLayout layout = new VLayout();
		layout.setWidth100();
		layout.setHeight100();
		layout.setMembers(positionGrid,sortButton);
		layout.draw();
	}
