Skip to main content




Dictates if the module occurs before or after the action form.

Possible values: "preFormAddon" or "postFormAddon"



Function to execute after the Next button is pressed. This function should query the content of the module and decide if it is valid.

The function should return boolean true if the content is valid, and false if it is invalid. You may also return a string when the module content is invalid, and this string will be displayed as an error message. If just the boolean false is returned, the default error message will be "Invalid Input".
