An ELException saying "Cannot add parameters to a MethodExpression pointing to
cc.attrs" will be thrown now at the time the MethodExpression for the composite
component is created.
> Indicate a better error message if a composite component MethodExpression
> includes parameters

> If you use something like this
> action="#{cc.attrs.method(cc.attrs.param)}"
> inside a composite component, you will get an unclear ELException, saying
> "Method method not found", because the ValueExpression which retrieves the
> MethodExpression from the composite component attribute map does not support
> params (of course). Thus a better exception message is clearly needed in this
> case.
