I haven't been following the previous entries in this thread, but, in
this example, the easiest solution is to create a method in one's bean
called, for example, getListSize():
public int getListSize() {
return this.getList().size();
}
and then code it in one's JSP as:
<h:outputText value="#{bean.listSize}"/>
True, it means creating another method in one's bean, but it makes the
JSP easier to follow. The code has to be written either way. Using
JSF, it is written in the bean, and it results in more concise and
self-documenting code in the JSP.

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

Alex
