Hmm, this means that at the point where the JSP is written to the output
stream the output from the other (enclosing) elements has not been
committed. However, I cannot see the problem in code I provided. I am using
it extensively, and David Sean Taylor [EMAIL PROTECTED]
reported success on it as well. Did you implement the getContent() method in
your portlet as described in my mail?
