Most certainly you should override BeansWrapper.getModelFactory. And
then, instead of MapModel, CollectionModel, etc, you had to create
sub-classes of those where getAsString (inherited from StringModel) is
overridden.

Of course, it's quite awkward that you can't just override getAsString
in StringModel, but that's just one of the many cases where
inheritance is not flexible enough. I wonder if
StringModel.gasAsString should call back into BeansWrapper so that
there's a single point where you can control its behavior. Then you
don't even need to override getModelFactory. I just wonder if it's
useful enough in general to introduce the (small) overhead that the
indirection means.

Nope.
