Checkbox is abit of a bad example, A DropDown or anohter Choice is a better one
Converter is Type conversion String to Date or Integer or what ever.
But convertValue (used in the Choice classes) is not type conversion
But it is more a Lookup conversion (or how do i say this better)
The input/request value is an id and for that id a object is lookupped..
The normal converter can never do that. Because it doesn't have any context
(The Choices List and the IChoiceRenderer in this case)
But as i said we always try to use the converter of the component.
But for this particulair case we don't have the component.
Maybe we should have a getRootObject(Component) and setRootObject(Component) methods
in the ICompoundModel interface, So that we can give the component to the model.

Yeah, I'm not totally crazy about that either. But the fact that we
only try to convert when there is a converter set comes from:
* some components, like CheckBox use their own kind of conversion, and
thus override the convertValue method
* some users strongly objected against Wicket always trying to use
converters. In older Wicket versions, it was integrated in it's
adoption of OGNL. But users wanted less magic.
