> Issue Type: Improvement
> Components: tapestry-core
> Affects Versions: 5.2.4
> Reporter: Howard M. Lewis Ship
> Assignee: Howard M. Lewis Ship
>
> 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.
