I assume you are calling your handler this in a "beforeCreate" event?
Try moving the handler to an <!initPage /> event at the top of the page:
<!initPage
yourHandler(...);
/>
Unlike "beforeCreate", "initPage" gets invoked every time the page is
refreshed. You can probably move your List into a request attribute
when you take this approach b/c you will be regenerating the data every
request.
I hope this helps!
