CubeGrid: tree facet cannot be expanded if setHideEmptyFacetValues is true

[addy_hu]

The version of smartGwt: smartgwtpower-3.1d-2012-11-19(nightly build)+analytics module
The browser is firefox

In the cubeGrid, if I set hideEmptyFacetValues to true, after I collapse a tree facet, it cannot be expanded again. This problem disappears if hideEmptyFacetValues is set to false.

I create a simple test case whose data is copied from the exemple "Basic CubeGrid" in the Showcase:

public class BasicCubeSample implements EntryPoint {  
  
    public void onModuleLoad() {  
        Canvas topCanvas=null;  
        if(SC.hasAnalytics()) {  
            CubeGrid cubeGrid = new CubeGrid();  
           
            //Use the data from the exemple "Basic CubeGrid" in the Showcase
            cubeGrid.setData(ProductRevenueData.getData());  
  
            cubeGrid.setWidth100();  
            cubeGrid.setHeight100();  
            cubeGrid.setShowCellContextMenus(true);  

            //Here set HideEmptyFacetValues to true
            cubeGrid.setHideEmptyFacetValues(true);  
            cubeGrid.setHideEmptyAxis(Axis.ROW);
         
 
            //Define the column facet
            Facet month = new Facet("month","month");
            month.setValues(new FacetValue("January","January"), new FacetValue("February","February"), new FacetValue("March","March"));
            
            //Define the row facet which is a tree, suppose that "Pens" is the summary node, and "Chairs", "Monitors" as its details nodes
            Facet product = new Facet("product","product");
            product.setIsTree(true);
            product.setValues(new FacetValue("Pens","Pens"), new FacetValue("Chairs","Chairs","Pens"),new FacetValue("Monitors","Monitors","Pens"));

            cubeGrid.setFacets(product, month);

            cubeGrid.setColumnFacets("month");
            cubeGrid.setRowFacets("product");
            
            topCanvas = cubeGrid;  
        } else {  
            HTMLFlow htmlFlow = new HTMLFlow("<div class='explorerCheckErrorMessage'><p>This example is disabled in this SDK because it requires the optional " +  
            "<a href=\"http://www.smartclient.com/product/index.jsp\" target=\"_blank\">Analytics module</a>.</p>" +  
            "<p>Click <a href=\"http://www.smartclient.com/smartgwtee/showcase/#cube-basic\" target=\"\">here</a> to see this example on smartclient.com</p></div>");  
            htmlFlow.setWidth100();  
            topCanvas = htmlFlow;  
        }  
        topCanvas.draw();  
    }  
  
}

Is there any news? I am always blocked by this bug.

I tried to add canMoveFacets:true in the online example: http://www.smartclient.com/#analytics today.Under my browser iceweasel (firefox) 16.0.2, the collapse/expand function still doesn't work correctly.
However under chorme, there is no such problem.
So the bug is linked to the browser. I hope that the smartgwt team can repondre soon, my project is always blocked by this problem.

I am sorry, I made a mistake, actually I mean "I tried to add <b>hideEmptyFacetValues</b>:true in the online example: http://www.smartclient.com/#analytics today."
