Subject RE: setTemplate using JSPAction (or even GenericMVCPortlet/PortletAction now)
Date Mon, 08 Sep 2003 19:28:17 GMT
Why don't you log this into Bugzilla - someone will look into it.

Although, I believe that Jetspeed Questionnaire portlet switches jsp
templates at runtime. Take a look at that but perhaps it's broken too :-(

Best regards,
