[jboss-user] [JBoss Seam] - Unwanted datamodel update on action cancel

[blabno]

I have 2 pages : 
 A) data table with entities representing countries
 B) edit form used to edit name of selected country
Now, when i select country on page A, the form loads with input field loaded with country's name. I change value of that field to whatever else and press cancel button which takes me back to page A. But name of country that i just quit editing is changed (and even persisted) ! I do not want such bahaviour. What should I do ?
btw. same thing happens in demo application dvd-store when you change products quantity in cart and press "Continue shopping" instead "Update and recalculate total", which in my opinion should not cause amount in cart be changed.
