> I've encountered a bug in T5.1.0.5 where a form that submits via ajax (i.e.
> The form has its zone parameter set) will never notify the user if the
> server-side action fails. I've traced it down to this line in tapestry.js:
> // Set a default failure handler if none is provided.
> options.onFailure |= Tapestry.ajaxFailureHandler;
> This line is in the sendAjaxRequest function that gets added to all form
> elements via Prototype's Element.addMethods function. I used firebug to
> debug the above statement and instead of the OR assignment that it looks
> like, options.onFailure actually ends up being assigned the value '0'. I
> guess this means that its only a bitwise operation and can't be used for
> functions etc.
