PS. :)
1) There's an easier way to do this than what I said in my last e-mail. :) A
ComponentAction is executed in the order in which it is stored. The problem
here is that you're storing it in the SetupRender phase, which is before the
form components store their actions for updating the values. So change just
the render phase method from setupRender to afterRender and you should be set.
2)I was thinking about other ways to do this. You might be able to write a
custom binding that understands your conventions.
Eg: <t:checkbox value="yourbinding:object.newsletter;0;1"/> Now yourbinding can
extrapolate the information that you need directly from the objects without
resorting to custom ComponentAcions all over the place.
