Designing Application Task Flows

The key to effective application development is defining the task flows involved in modeling business processes. In the Application Composer, you can graphically design an application task flow.

Context

The first time you open the Application Composer, you see the Start Application state. If you select the state, the state editor opens, which allows you to add follow-up states.

You can rearrange a layout by dragging and dropping state icons. To get a better view of state transitions, you may want to rearrange the layout, particularly when transition lines overlap. You can drag and drop state icons into fixed-grid positions on the canvas. The canvas does not allow free-form positions. Transition lines are automatically positioned, and you cannot move them.

Procedure

  • To move a state, select it, and drag it to an alternate grid position.
    While moving, the state icon appears transparent, and the target grid positions are highlighted when the mouse enters the grid area.
  • To delete a state, select the state, and click Delete.
    When you delete a state, all transitions to and from other states are deleted. However, corresponding states and all of their downstream flows are not deleted. States that are not connected to other states become orphans, but they are still accessible from the follow-up state list, and you can connect them to other states.
  • To save a rearranged layout to the database, click Save Layout.
  • To revert the application layout to the last one saved in the database, click Revert Layout.
  • To change the grid lines, expand the Gridlines list, and select All, Partial, or None.
  • To zoom in or out, expand the Zoom list, and select the magnification you want to see, relative to the initial display.
    If you zoom out from the default 100% view, you must reset the zoom level back to 100% before you can make any layout changes.
