That's a fantastic idea, I'll definitely do that.
There is one problem, because the validation is actualy coming from the
domain objects "setters", I don't know if there was a problem until the
"updateModel" method is called... I don't know if I like calling
"updateModel" from the validator, since I'm not sure whether that will break
other things down the road, I'll try it and report back.
Is there a way that I can retrieve the setter, so that I can set it, and
then return it to it's initial state before the form calls 'updateModel' on
it's children? Perhaps the component can only take PropertyModels?
