Hi,

I am working on Portlets application on webspear portal. One of my Jsp is giving "NestedNullException". I am using <display:table> tags from taglib(<%@ taglib uri="http://displaytag.sf.net" prefix="display"%> . If i remove this tag it is showing empty page. if i put it it is thorwing the exception. Can anyone tell me how to resolve the problem. the stacktrace is below.
