When I do submit redirect to the correct page (/app/emailFailed) but puts on url a parameter called "refno" how can i modify that and put my own parameters?

Answer 1

The refno field is a standard parameter added to the out-of-the-box controller that your form is submitted to. If you need to alter the URL parameters, then you'll need to create a custom controller that can perform the action of submitting your form and adding the parameters that you need. The easiest way to do this would be to create a new controller that subclasses ajaxRequest so that you can override the sendform method with the logic that you need to implement.
