Right, but the problem is that there is the potential
for multiple dropdowns on the same page and I want all
of them to update the form's model. I think I've done
everything wrong. I'm really confused with how the
model is being passed around.
Since I have the form include a panel which includes a
form component, how can I have that form component
(e.g. dropdown) update the form's model. I was able
to get the whole thing to not give me a RuntimeError
anymore only when each separate form component has its
own private model, but this does not help me, since I
have no way of accessing that model from the form's
onsubmit method.
The way I have it set up now is that the form has a
model of ArrayList. I thought the ArrayList would
fill with a list of CategoryQuestionResponse objects
that were selected on the page, which is not the case.
Instead it remains empty. So I guess the crux of my
problem is how to fill in the form's model and not
each component's private model.
Thanks again for your help, I really appreciate it.
