I've asked the same question under Knowledge Management, but perhaps it's better at this point:
I've installed the CRM Business Package 60.2.3 on NW EP 6.0 SP13. On the first page where the news comming up I got now the error "Resource cannot be displayed with XMLResourceRenderer" for every news which i wrote. If I try to write a new news (SAP Demo News) I got a error page: "Error using the XSL Stylesheet on XML com.sapportals.wcm.WcmException: com.sap.engine.lib.xml.util.NestedException: Error writing output. -> java.lang.ClassCastException
I think it have something to do with the news which comming with the Business Package for CRM.
Have anybody a idea how I can solve the problem or which part in the portal was destroyed?
Many thanks. Regards
