Calling resultList.size() on framework entity-query with max-results= set gives error ------------------------------------------------------------------------------------- Key: JBSEAM-1756 URL: http://jira.jboss.com/jira/browse/JBSEAM-1756 Project: JBoss Seam Issue Type: Bug Components: EL Affects Versions: 2.0.0.BETA1 Environment: JBoss-4.2.1.GA Reporter: David Spark Assigned To: Pete Muir Priority: Minor Fix For: 2.0.1.GA I'm trying to get the number of results from the following query (in components.xml): Code: <framework:entity-query name="clients" ejbql="SELECT c FROM Client c" max-results="20"/> And this is in my page: Code: <h:outputText value="#{clients.resultList.size()} clients available"/> But when I try to load the page I get the following error (I also use the query to create a dataTable and that works fine): javax.faces.FacesException: javax.el.ELException: /clientSelect.xhtml @14,77 value="#{clients.resultList.size()} clients available":
