Can you make a link to the Richfaces Forum entry. I cannot find any solution to the file upload problem there. I always get a ClassCastException using rich:fileUpload: java.lang.ClassCastException: org.jboss.portal.portlet.impl.jsr168.api.PortletSessionImpl at org.richfaces.renderkit.FileUploadRendererBase.getSessionId(FileUploadRendererBase.java:686) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4186019#...
