ListGrid Date filter is not working

Some one tell the issue, why the date range filter is not working for ListGrid.

code :

ListGridField date = new ListGridField("date");
date.setTitle("<B>Date</B>");
date.setCanEdit(false);
date.setAlign(Alignment.CENTER);
date.setCanFilter(true);
date.setType(ListGridFieldType.DATE);
date.setDateFormatter(DateDisplayFormat.TOUSSHORTDATE);

Any example in SmartClient showcase?

When selecting the filter (From and To Date) in Select Date Range popup. ListGrid records is not filtering based on date range. Is it in smart gwt bug??
