Validator Cleaned existing formbean or generated new one

Question

Hi buddies,
I'd like to use struts validator in my project. It seems working but cleaning existing formbean or generating new formbean.
The case is: after listing all customers, user can choose edit or delete one of them. Supposed (and it works correctly before I applied validator in) the Action will find the client and populate the appropriate field value into form bean, and the form bean is to be forward to edit jsp page. But now, in the fields on the edit jsp page are blank, just like create new record.
it took me 2 days, and cannot fix the problem. Please gave me some ideas. Your any input is appreciated.
