I have a form panel similar to the example found in the doc and I am trying to set the url. However, the 'url' does not appear in the list of configs and properties even though it is in the example. In addition to this, whenever I try to submit my form, it always has a url of localhost/undefined, even though I set the url parameter everywhere I could.
TL;DR How do you set the destination url on a form panel.
Any help is greatly appreciated.
