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
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": java.lang.IllegalAccessException: Class org.jboss.el.util.ReflectionUtil can not access a member o
f class java.util.SubList with modifiers "public"
