All I want to do is stuff like:
class FValidateTextField extends TextField
{
public FValidateTextField(String name, Serializable object, String expression)
{
super(name, object, expression);
add(new FValidateAttribModifier(this));
}
}
There's nothing wrong with wanting to do that, is there? I mean, by adding such a modifier to instances I really introduce new behaviour which thus satisfies the inheritance requirement of behaviour, but it is still a text field that uses the normal text field rendering behaviour.

And this is not possible using delegation? Or would that be too much effort on the developers part?

When working on the contrib section, it's quite irritating that most form component implementations (like TextField etc) are final. What I would like to do a lot (and think other users might as well) is just override such a class and provide a custom constructor that adds eg some attribute modifiers or validators. I also think this would be quite a common use case for users that want to implement their componany std's components etc.
I would like to propose to make the form components non-final *but* finalize all important methods that have component specific implementations (like handleComponentTag or handleBody) final.
Any objects/ what's your vote?
