After you have created or edited an application, you save the Application in your environment using the Save Application menu function.
When you save an application, a series of validations is executed to ensure that required components have been included in your App (for example, including an ID field in a repeating Display Map where you also have a Save Map). It then saves the changes you have made to the Application.
The Save Application button is divided into two parts.
Click the top half of the Save Application button to save the Application. This updates your environment with the updated template and configuration.
Always save your Application after you have completed work in any menu function (for example, Save Map or Display Map).
Click on the bottom half of the Save Application button to Save As or Clone the Application. X-Author suggests a new name but you can type in a name. This creates a duplicate of the App with the new name.
