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...
