Re: How to mock Listbox when testing the Presenter class?

"I'd highly encourage you to use the pattern from the "MVP - part 2"
article
from the GWT doc, where the presenter itself implements an interface
that
the view calls back, rather than exposing the view through
HasXxxHandlers
and the like."

==> Can you elaborate more on this? My only question here is if my
presenter implements the interface and view has the method call
setPresenter which basically binds that presenter to the View, how
does the view calls back those methods implemented in the Presenter?
Does view need to pass every UIField in the method call to Presenter?
That is where I am lost here. Sorry I am new to GWT but I want to be
perfect so asking lot of questions.
