With a form running inside an iframe, and the user makes changes to the form, how can I prevent or notify the user of unsaved changes when they navigate away? Say they hit the back button or click a button on the parent iframe page.
The form does have a mechanism for detecting change and then warning the user about leaving without saving those changes. It sounds like that behavior doesn't work the same way when the form is embedded and the navigation is performed at the parent.
I am not sure there is anything we have at this time to help with that situation.
