Possible to access bean property without Java Bean conventions?

Question

Hello,
I'd like to show a component whenever there is an error message in the Faces context. Naively, I set the component's "rendered" attribute to the following:
rendered="#{facesContext.messages.hasNext}"
The object returned by facesContext.messages is an iterator, the properties of which do not follow Java Bean naming conventions. If there was a method called getHasNext() then all would be well. However as it stands, EL cannot evaluate this expression.
I realise that wrapping this up in a managed bean would solve the problem, but I'd like to avoid this if I am able to do this directly from EL.
Cheers,
Chris

Hi Juergen,
hasNext actually returns a boolean which EL understands fine. In the end I just wrapped the call within a managed bean, as you suggested, and this works a treat:
  public boolean getHasMessages() {
    // hasNext will return true if there are any messages to be displayed
    return FacesContext.getCurrentInstance().getMessages().hasNext();
  }I suppose I felt compelled to post this entry since I found myself having to write some code for an expression that could be written perfectly well in EL but was limited only by the fact that EL can only access properties that follow the Java Bean convention.
I thought that may have been some qualifier or method wrapper I could have used to mean 'take this property name literally'. Alas, it seems no such faclility exists.
Thanks for taking the time to reply,
Chris.
