I had the class implement Serializable already but it still couldn't
work.
My problem was solved when i add on what i missed out - the gwt
notation above the method.
/**
* @gwt.typeArgs <xxxxxxxxx.gwt.dto.NodeDataChartDTO>
*/
public List getNodeDataChartData(Long nodeDataId, String strType)
throws ClientException;
Thanks.
