I have the following rich:dataTable, and do not want it to render if there are no results. The data is coming from the backing bean.

<rich:dataTable value="#{variableMatches}" rendered="#{not empty variableMatches}"
var="sel" id="libraryList" rows="20"
rowClasses="row-even, row-odd" columnClasses="dataCell2" >

...

It currently renders even though there are no rows.
Any suggestions?
