Rational Developer for System z, Version 7.6

4. Building a terminal flow

The fourth page of the New Flow wizard, titled Building a terminal flow, allows you to quickly create a set of Invoke screen operation nodes in the new flow by selecting existing screen interactions.

For this page of the New Flow wizard to be available, you must select the check box Build terminal flow from screen operations files on the first page of the New Flow wizard.

On the fourth page of the wizard, each time that you select a screen interaction and click the Add Action button (alternatively, you can double-click a screen interaction) the wizard creates a new Invoke screen operation node inside the new flow and initializes the node with the relevant information from the selected screen interaction. You now have a working screen operation Invoke node (assuming that the screen interaction contained all the proper information) that can manage the application screen for which the screen interaction was created. (For more information see Learn more about the artifacts).
Note: This page of the wizard does not allow you to arrange the new screen operation Invoke nodes in a particular order or to create or remove connections between nodes. Use the flow editor to perform these operations.

The main components of this page of the wizard are as follows:

To use this page of the wizard:

  1. In the Screen Operations Files pane, expand the entry for one of the service flow projects and then select a screen operations file that contains a screen interaction from which you want to create a screen operation Invoke node.
    Note: You can select a screen operations file from any service flow project in your workspace. You can select multiple screen operations files.
  2. In the Screen Interactions pane, expand one of the screen operations and then select the screen interaction that you want to use.

  3. Click Add Action. (Alternatively, you can double-click the screen interaction in the Screen Interactions pane.) The wizard creates a new Invoke screen operation node using the selected screen interaction and its associated information. The new Invoke node is displayed in the Flow Outline pane of the wizard page.

  4. When you have finished creating Invoke nodes, click Finish:
    1. The wizard opens the new flow in the flow editor.
    2. The wizard closes.
    Note: The New Flow wizard does not allow you to leave this page (the Finish button is disabled) if the last node that you added to the flow was created from a screen interaction that contains an AID key input action. The presence of an AID key input action in the screen interaction implies that the host receives the AID key and displays a next screen. Therefore a screen interaction for the next screen must be selected. The wizard displays the following message in the message area at the top of the page:
    The last screen interaction contains an AID key input. A next screen
    is required.
    To resolve this problem, add a screen interaction for the next screen that contains only output actions (Extract actions) or that contains no actions at all.

The following list describes the other features of this page of the wizard:
