I have a New Form button which opens a new page, on that page user can click on an icon which will open a pop up and will show users to choose from one of the three options. Whichever option user selects needs to be shown in the parent webpage in a text field. Even after setting rebuild all pages its not updating the textfield. I have also tried setting the initial option and page load actions. I am updating the app state variable and that will be updated using "Set Form Field" in the parent page on page load. Please help
