John, I just had this same error but the solution wasn't related DisplayTag. In my case, I was putting the <portlet:renderURL/> tag inside of a <c:set var="blah"/> tag.
So, I was trying to do this: <c:set var="renderUrl"> <portlet:renderURL/> </c:set> Apparently, you cannot do that. Once I just removed the <portlet:renderURL/> tag and just put it right into my <a href> tag, it worked fine. Hope this helps. Thanks, Eric --- John O'Reilly <[EMAIL PROTECTED]> wrote: > This is the full stack trace. > > > Nested Exception is javax.servlet.jsp.JspException: > actionURL/renderURL Tag Exception: cannot write to
