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

Use Facelets' built-in Jstl Function library.

  | <h:outputText value="#{messages.no_keywords}"
rendered="#{fn:length(advertisingCampaign.keywords) == 0}"/>
  | 

make sure you register the namespace for fn

i.e 

  | <html xmlns:fn="http://java.sun.com/jsp/jstl/functions">
  |
