| The thing to remember is that the Submit component will trigger its "selected" event in the |
| <em>middle</em> |
| of the form submission, before the form triggers its "validate", "success" (or "failure") and "submit" |
| events. |
| Thus the best thing to do is to store in a temporary field what should be done inside the "success" |
| event handler. |
