Are you under the impression that EL functions cannot accept

Just again to this point of the discussion:
I tried myself to write a function that would return the size of a
java.util.List passed as parameter. However, it works fine with JSTL
(core),
<c:out value="${my:listSize(bean.list)}" />
but when I try to use the same thing with JSF-EL of myfaces like this:
<h:outputText value="#{my:listSize(bean.list)}" />
it does not work. Take a look at the error message:
javax.faces.el.ReferenceSyntaxException: Functions not supported in
expressions. Function: my:listSize
And you cannot set a JSTL-expression as value of a myfaces-component.
Just for your info
