Description

We did an upgrade from 1.4.9 to 1.4.12 and noticed that a custom subclass of Form behaves differently. To submit a form by means of Ajax, we added an AjaxFormSubmitBehavior to the form triggering the "onsubmit" event. This worked until we did the upgrade. Now the javascript error "Error: too much recursion" occurs on submitting the form. This leads to a non-ajax submit of the form. I suspect that the code that AjaxFormSubmitBehavior attaches to the onsubmit event triggers onsubmit again - leading to an infinite loop. We now downgraded to 1.4.10. So the bug may first occur in 1.4.11 - but that version wasn't tested.
