The columns component architecture does not allow using of request scoped page attributes in expressions for columns attributes. Because iteration tags vars is initializing on rendering phase. So we try to get data from the vars in columns JSP tag before vars have been initialized. Example: <rich:dataTable value="#{bean.data}" var="var"> <rich:columns value="#{var.columns}" ...> This code will be a case of JSP tag exception. We need to change developer guide to avoid the error. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
