I've created a patch for submit component
https://issues.apache.org/jira/browse/TAPESTRY-2109
ior you can try this component (iti is a modified copy of original Submit)
public final class Submit2 extends AbstractField
{
static final String SELECTED_EVENT = "selected";
static final String CANCEL_EVENT = "cancel";
/**
* If true (the default), then any notification sent by the
component will be deferred until the end of the form
* submission (this is usually desirable).
*/
@Parameter
private boolean _defer = true;
/**
* Determines the button behavior, <b>"submit"</b> - a normal form
button, <b>"reset"</b> - reset form (locally),
* "cancel" - works like an actionlink, generates a "cancel" event
instead of "selected" and the form is not submitted
* (if javascript is disabled form will be submitted, and "cancel"
event fired as well),
* <b>"submitcancel"</b> - works like "cancel" but behaves
consistently with and without javascript
* submission (this is usually desirable).
*/
