Description

Although it is possible to determine that a form has been cancelled by providing a listener to the appropriate Submit/LinkSubmit component, that will often occur after other parts of the form have resulted in updates to server-side properties. That may be valid is some circumstances, but it would be nice if there was an early event notification from the Form that indicated a client-side cancel so that the processing of the form's data could be avoided entirely. That is the more general case: no updates to anything on the server side when a client-side form is canceled ... but there is not currently a simple way to determine this.

What's needed is a special parameter included in the form submission to indicate that the form was cancelled.
