Hi,
it is true that it is not possible to use method parameters or to call
methods of an object that are no getters or setters (at least before
Java EE 6).
But there are ways to bypass this limitation:
* If you only want to call a method in an EL expression you could define
an EL function (possible with JSP and Facelets).
* If you want to pass a parameter to an action method you could use an
alternative EL implementation like JBoss EL (see [1]). For this you have
to include the JBoss EL libraries and replace the expression factory of
MyFaces like this in your web.xml:
<!-- Replace ExpressionFactory for Apache MyFaces -->
<context-param>
<param-name>org.apache.myfaces.EXPRESSION_FACTORY</param-name>
<param-value>org.jboss.el.ExpressionFactoryImpl</param-value>
</context-param>
regards
Michael

Hi,
calling methods with parameters is not possible in JSF as far as I know. Try to
set Parameter in Bean before calling the method and then refer to it in your
parameter-less method.
Yours,
Martin
