I use this rendered="#{not empty facesContext.messageList}" to render a form. All works fine but my eclipse marker says the following warnings:

Warning1:This empty expression always evaluates to false. Only string, maps, arrays and collection have meaningful values for the empty operator.

Warning2: This not will always result a value of true.

I use Eclipse Kepler for it. Can i ignore this?
