Nobody ran into this? I have a feeling that I'm doing something wrong,
but then, I'm not sure either if Tapestry is just not working as
expected.
If I make the stateUpdateZone wrap entire form, then form is aware of
state value change. But I do not want to refresh entire form, all I
want to update is my little zone which I want to wrap state select in.
