> When using a4j:ajax and setting the listener to a bean method, the call works 
> correctly if the bean method has one parameter of type AjaxBehaviorEvent.  If 
> the method has no parameters then it may not be called correctly.  This 
> situation occurs if the method expression uses a variable scoped in facelets. 
>  For example using a ui:param under a ui:decorate.  The method expression for 
> one parameter is created using a call to 
> ExpressionFactory.createMethodExpression( faceletContext, ... ) but the 
> method expression for zero parameters is created using 
> ExpressionFactory.createMethodExpression( elContext, ... ).  The elContext 
> does not contain the facelet variable mapping and so will not impart this to 
> the method expression.  This needs to be refactored to pass in the 
> faceletContext when creating the zero parameter method expression.
