Hi,
so I've had to add some mixins to a form to conditionally handle some
form elements based on used input. A user selects a certain select list
option, some fields get disabled or enabled as a result type thing.
The form is actually a BeanEditForm, not just a Form. Anyway, when my
mixin returns back to the Page class event method which in turn updates
the Zone, I lose all the values the user filled out in the form.
Understandable enough, they were only living on the client side until
the mixin-zone update occurred. As far as I recall Zones embedded in
Forms don't really work out, hence my zone wraps around the form in its
entirety.
Is there a good way to deal with this scenario? I was thinking there
might be some way to tap into the binding to the Bean object that the
BeanEditForm does during form submission. That would be ideal. I think
the onPrepareFromForm method does what I want:
From BeanEditForm.java @ line 141
void onPrepareFromForm()
{
resources.triggerEvent(EventConstants.PREPARE, null, null);
if (model == null)
{
Class beanType = resources.getBoundType("object");
model = beanModelSource.createEditModel(beanType,
resources.getContainerMessages());
BeanModelUtils.modify(model, add, include, exclude, reorder);
}
}
Of course it's calling some internals and I don't think I can just do
this from my page class. Is there some way to get the BeanEditForm to
store the form values into the property bindings?
Also, I know it's possible to pass all the form values through as
request parameters via AJAX and copy them into the property bindings of
the form elements manually, but that seems pretty excessive. I hope
that's not my best option =/.
Thanks,
Rich
