Hello, On my xhtml page I've the following tag: | <a:mediaOutput element="img" cacheable="false" session="true" createContent="#{quoteAction.generateChart}" mimeType="image/png" /> | And it seems that this entry causes the following exception as it is looking for an outputstream to write the image: | 15:39:45,557 ERROR [home_prototype_portal_quote_portlet_QuoteListPortlet] The portlet threw an exception | javax.faces.FacesException: java.lang.NoSuchMethodException: org.jboss.portal.portlet.impl.jsr168.api.ResourceResponseImpl.getOutputStream() | at org.ajax4jsf.resource.FacesResourceContext.getOutputStream(FacesResourceContext.java:124) | at org.ajax4jsf.resource.UserResource.send(UserResource.java:108) | And obviously, the method getOutputStream does not exists as it is getPortletOutputStream. Does someone knows what I could have misconfigured. Regards, View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4251024#...
