public class MethodParam
This handler wraps a value expression that's actually a method expression by another value expression that returns a method expression
that gets the value of first value expression, which as "side-effect" executes the original method expression.
This somewhat over-the-top chain of wrapping is done so a method expression can be passed into a Facelet tag as parameter.
