HCM Process & Form Start Process Close Button not Working

Hi,

For initiating HCM process we have used ASR_PROCESS_EXECUTE_FPM Application. When Manager selects any process for an employee and goes to the Start Process Step then there are 4 buttons Previous Next Close & Save As Draft. When the close button is pressed one pop up comes with message "Do you want to Discard Form Data?" with two buttons Ok and Cancel. If Ok button is pressed nothing happnes. The pop up remains on the page & the page is not closed.Can anyone give some light in that issue.

Regards,

Sandip
