Hi, If your onAction method is called, it's a good start. Next check in Firebug Net panel if the field value is being sent to the server. You only need to register the Form as an Ajax target. Also look at the logs in trace mode for anything suspicious.
If all else fails can you post your code here which reproduce the problem?
