Did you miss my response? Much better than trying to handle the final submit
yourself. Here it is again...
Try a Tapestry AJAX Form with two Submits: one visible and one hidden. Add
JavaScript that listens to the click of the visible submit, stops the event
propagating, does the call to the external service and, on success, sets the
value of the form field (which might be a hidden field) and clicks the hidden
submit.
Here's a standard AJAX Form:

Here's some JavaScript that listens to something:
