Re: what is the appropriate MVP way of doing this?

That's great! Thanks Thomas.

I've got another question (well, a set of questions) - say you have a
text field in the view that you want to reference - to receive click
events as well as key up events.

1) Would you reference the text field as HasText and cast to the event
2) Would you create some modified interface that extends from all of
the desired interfaces?
3) Or, would you do something completely different?

Again, thank you very much for the help.
