I now have the due date arriving OK from the jQuery datepicker, and I
cobbled together some ugliness to give days left until the ToDo due
date, so that is good.
My problem now is since we are not using the 'magic' of the _toForm
methods for the form elements, I have to set each var value for the
model field from the input SHtml data, as was done in the PocketChange
app AddEntry.scala file.
What is happening is that the initialization for each var is resetting
the form if validation fails, so I guess I need to institute some
RequestVars to remember the form values for resubmission, right?
All my questions will take take the form of 'how to' recipes of
foundational webapp elements, as you can see. My plan is to develop
them for a 'cookbook' section of the wiki, so that's why I am asking
one simple conceptual thing at a time.
Therefore, what I have to learn now is all about form binding and
recalling form value state if validation fails, so please break that
down for me.
Thanks as always!
