Hmm, yeah perhaps it should be a behavior which we should be able to add to
the form instead. And the register the components which would like to have
default focus.
I don't think it's necessary to have it as an interface which should be
implemented. It feels a little intrusive.
I'll take a look at it later to see what I can come up with.

Frank Re. solution proposed below (with FocusBehavior) you can get the
markup id for whatever field you chose determined by how you write your
getDefaultField() method in the class implementing the interface
FocusBehaviour. One option would be to have the method traverse all relevant
form components checking their model objects for values and then return
markup for whichever one you like. You may even want to append each valid
selection into a list and use that as the basis for a rule on which gets the
focus. Hope this helps you formulate a strategy.
