Yeah, after you explained further, I knew that was going to be problematic. :)
Try formSupport.defer(Runnable command);
The runnable will get executed after all other actions, just before the form's
validate event is fired, so the values will be updated at that point. But
you'll have to defer the action during the form submission, so basically: store
a component action. The ComponentAction will invoke formSupport.defer(new
Runnable() { /* code to update your values goes here */ });
Incidentally, you mentioned validate in your previous e-mail... each form
component fires its own validate event, so the validate event you mentioned
before is not the Form's validate event bubbling down to the components, it's
the validate event fired by each form field.
Cheers,
Robert
