Thanks for everyone that's helped me out with my Wash questions. I have
I have a textInputField that I only want to display on a form in certain
cituations. I can't figure out how to make this work. For instance:
... do if cond
then x <- textInputField ...
Well, two problems there... first, the scope of the x doesn't reach to
the submit. Second, there's a type issue. So I thought maybe I could
figure out something like this:
... do x <- if cond
then textInputField ...
still stuck with the typing problem.
So I thought maybe something like this...
... do let x = if cond
then Just $ textInputField ...
Though I suspect this won't work either, since the textInputField won't
actually be processed at the right place in the program.
I then thought maybe I could kludge by this with a hidden field, but I
can't find one of those, either.
