[jsr-314-open] MethodRule API

[Cay Horstmann]

The MetaRuleset mechanism is another one of those aspects of JSF that 
just reeks of excessive complexity, combined with a half-assed API and 
useless docs. It took me a day of reading through a tangled web of 
source until I figured out how to implement my own MethodRule since the 
standard provided none.

Instead of providing a standard MethodRule class, why not just add a method

void addMethodRule(String attributeName, Class<?> returnType,
    Class<?>... paramTypes);

to ComponentHandler?

Then I can do this:

public class SpinnerHandler extends ComponentHandler {
    public SpinnerHandler(ComponentConfig config) {
       super(config);
       addMethodRule("atMax", Void.class, ActionEvent.class);
       addMethodRule("atMin", Void.class, ActionEvent.class);
    }
}

Or even better, provide a way of declaring this in the taglib.xml file 
without any coding. Then I wouldn't need a handler at all.

Cheers,

Cay
