JSF EL - empty operator

Wed, 15 Nov 2006 02:27:12 -0800

Hi,

 

Is the empty operator of the JSF EL working ?

I want to display some text if an ArrayList is empty, but this does not work in my case

 

snippet:

<t:dataList id="results" var="cat"

   value="#{MyController.filters['key'].values}">

...

</t:dataList>

<h:outputText value="***no results found***"

  rendered="#{empty MyController.filters['key'].values}"/>

 

 

MyController.filters['key'].values is an empty ArrayList.

Are there any alternatives to check whether a collection is empty via EL ?

 

Michael
