[jboss-user] [JBoss Seam] - EL and accessing .size or isEmpty

[tony.herstell@gmail.com]

A coding question ... with EL how do I get to things like .size.. or .isEmpty  its seems very hard to get to!!!

I have this... 

  | <h:outputText value="#{messages.no_keywords}" rendered="#{advertisingCampaign.keywords == null}"/>
  | 

and want this

  | <h:outputText value="#{messages.no_keywords}" rendered="#{advertisingCampaign.keywords == null || advertisingCampaign.keywords.size == 0}"/>
  | 

But size is "not a property" and incidently nither is isEmpty !!!

keywords is a LinkedHashSet (to ensure retreival order matches insertion order) and I am pretty sure that this is NOT a factor...
