Creating Page Flows : How Actions Get Data

How Actions Get Data
Every Action implicitly contains a special variable called message. The message variable contains the “backing” data of the Page to which the Action belongs. The backing data for the page is defined by the Page Message for that page (Page Message). When the Action is invoked, the ActiveGrid Server updates the Page data with whatever the user submitted when the Action was called and then passes the updated data into the Action’s message variable (with the user’s changes applied).
When you customize an Action, you can define your own Action variables and populate them with data.
