Problem while resetting values

suresh dasari wrote:Hi Balaji,

why you need binding for an inputText, is there any specific reason?

An alternative for solving this issue is try to enclose the inputText in a panelGrid or panelGroup and in reset button click set the required value to '0' and rerender the panelgrid which will refresh only inputText with value set back to blank.

Thanks,
Suresh.

Thanks for reply. But i am not getting what exactly.
