The back buttons in forms, added using the wizard or navigation button fields, have several "back modes" you can choose from.
The options are:
- Back, no validation - The default setting lets you navigate back to the previous page as if the current page hadn't been visited. Values entered onto the page won't be saved and no action fields will be triggered
- Back, no validation (link) - This behaves in the same way as no validation, but outputs the button as a link. Back links are generally placed at the top of a page and are not triggered by pressing the Enter key
- Back, validate, actions/no actions - In this mode the back button will only navigate away from the page if there are no validation errors. Any values entered into the fields on the page will be saved (so will be present when you navigate "forwards" again). When performing validation it is also possible to control if action fields on the page are triggered or not
