FormComponentPanel & onchange Events
I've created a FormComponentPanel with 2 text boxes: A & B. I've add this
new FormComponentPanel to my page twice: 1 & 2. What I'd like to have
happen is when I change the value of 1A I want that same value copied into
2A.
I call setOutputMarkupId to true on 1A, 1B, 2A, and 2B. I setup
an AjaxEventBehavior on panel 1 and it fires as expected. However, inside
of the onEvent method all of the model instances I try to obtain are always
null (therefore preventing me from setting 2A). I've tried getting the
form's model object, the model object for panel 1, and even the model
object for A1... everything is always null.
Is there some method of FormComponentPanel that I'm not overriding that I
need to be? Any thoughts on how to make this work?
Thanks...

The model objects are only updated after form submission and submission
will only happen if successful validation has occurred.
If you are expecting to copy values from one field to another without
performing form submission then you can't extract the values from the
model objects.
I think what you might be looking for is the String getRawInput() method
on FormComponent which *I believe* returns the value that is currently
in the TextField.

I finally got some time to test a few combinations:
- onchange for panel, getRawInput() = null
- onblur for panel = event never fires
- onchange for field, getRawInput() = null
- onchange for field, getModelObject() = null
- same combinations as above but with AjaxFormComponentUpdatingBehavior;
always null
So just about all combinations still seem to only return null :-(
I put the code for my FormComponentPanel up on pastebin:

Any insight would be great.
Thanks...

William,
Is the AjaxEventBehavior added to the panel or the component? What event is it fired on?
I'd thought you'd need it to be added to the component (rather than panel) and say, triggered 'onblur'. And using a AjaxFormComponentUpdatingBehavior rather than AjaxEventBehavior?
Can you post the non-working code up if those suggestions don't solve it? I'd be happy to have a look at it.
Cheers,
Col.
