ListGrid FilterData Throwing Exception

[chodges]

Hello:

I'm kind of stuck on a problem with the ListGrid filterData function. Here is a snippet of code that illustrates the problem:

Criteria ca = new Criteria();
							
ca.addCriteria("attributeID", Integer.valueOf(response.getData()[i].getAttribute("id")).intValue());
_attributesList[i].setDataSource(ListSource.getCachedInstance());		
_attributesList[i].setCriteria(ca);							
_attributesList[i].filterData(ca,new DSCallback()
{
	public void execute(DSResponse response, Object rawData, DSRequest request) {
});

And that small piece of codes consistently throws the following exception:

Any insight you can give me would be greatly appreciated.
