Since I don't know if it is a bug on RF or on live demo, I'm posting on forum first.

Steps to reproduce the error:
1. Go to DataTable demo "Edit Table with ModalPanel" (great demo - I love it)
2. Click on any "edit" button
3. Replace "Make" and "Model" with anything (let's say "XXX" and "YYY")
4. Replace "Price" with an invalid value (like "AAA")
5. Click "store" (it will give a validation error)
5. Cancel by clicking on "X"
6. Try to edit any row

Expected result: the modal panel must show information from the selected row

Actual result: the "price" shows the correct value, but "make" and "model" shows "XXX" and "YYY"

I tested on FF and I didn't find any workaround, yet... Any ideas?
