To build an App, users can drag-n-drop components from the Components Section on to the Canvas.

On the App Process Modeler screen, a user can find the following items:

Connection Arrows

There are two types of arrows that are used in the Modeler.

  1. Navigational Arrows:
  • They are unidirectional arrows that is used for navigation of the sequence.
  • They can be added to the left, right, and top of the screen (page).
  • They are connecting arrows that enable execution outside the page.
  • The pages created within the App Modeler canvas can only be redirected to another page with the help of the navigational arrow.
  • If the arrows appear in dotted lines between components, it denotes that an Interaction is not yet added to the component.
    Invocational Arrows
  1. Invocational Arrows:
  • These arrows are bidirectional and are restricted to a particular page.
  • Using this arrow, a script or service (Behavior or BOS) can be written for a particular page.
  • The BOS written for a page using the invocational arrow can only be called by writing an Event for the particular page in the App Behavior section or through Interactions in App Designer Properties section. This BOS cannot be executed outside this page.
NOTE

The BOS will be called directly when logic is executed from one page to another if they are connected via navigational arrows.

Preview/Publish/Transport Icons

Preview of an app is commonly used during development. Once the development is deemed complete, Publish and Transport options are used in the deployment phase.
