I'm doing pretty much exactly that with my FileUpload widget, and it
works ok here:
/*
* User clicked the Chooser OK button.
*/
public void onSubmit(SubmitEvent p_event)
{
if (m_progressUpdateTimer != null)
{
// Upload is already in progress
p_event.cancel();
return;
}
.... several more validation checks ....
}
