Hello,
I'm trying to run a Portlet P.O.C. only with a JSPX page shows something in Webcenter Portal page and when I add my portlet to a page shows this error: Remote Portlet Error. But, when I add a P.O.C. portlet with JSP page work it.
The problem is that I need a JSPX page to add a taskflow to this JSPX page.
