Flow form
Editing in Visio — Creating and editing screen flows

Field

Description

Not used.

Select one of three standard harness rules that support screen flows, or a custom harness rule you have evolved on one of these three:

For an example of the tabbed approach, select View > Rules > Find by a Custom Field. This processing is defined by the standard rule PegaAccel-Task-Wizard.CustomFieldsWizard.

Supporting more than two levels of tabs

A second row of tabs appears when a user executes a subflow screen flow (that has entry points) that is called by a first-level screen flow. The standard final HTML rule Work-.NestedTabbedNavigation defines this limit. To support three or more levels:

   1. Copy this rule into your application with a work class as the Applies To key part, keeping the second key part.

   2. Update one line in the HTML Source field to specify the number of sublevels desired. For example enter 2 to support three levels of tabs.

tools.putParamValue("Levels", nnn);

3. Optionally, update one line in the HTML Source field to specify the name of styles for each sublevel, separated by commas:

tools.putParamValue("ChildNodeStyle", "style1",
"style2", );.

4. Save the HTML rule form.

Select to cause the work object and work object history to be committed only once, after users complete the entire screen flow. Clear the Save Later? box to let users select a Save local flow action at each point in the flow. After a Save local action, users can continue processing this flow, perform other work, or log off.

As a best practice, select the Save Later? box in most cases, to reduce the number of work object Commit operations and history instances.

This field appears after you select the Save Later? box.

Select to allow users to, when executing a screen flow or a regular flow that includes breadcrumbs control, select another entry point even when the form (or tab) for the current entry point reflects validation errors. (The user must eventually clear all such errors.)

If not selected, users can advance to the next step of a screen flow, or click the breadcrumbs control only after data in the current tab is valid.

To prevent users from completing information that's never used, don't select the Allow errors? check box if the values in any entry point (for example, an Assignment task) directly or indirectly affect the outcome of a later Fork shape or Decision shape.

At runtime, a single user processes all assignments in a screen flow rule. Identify the routing applied to all these assignments. Select ToWorklist to route the assignments to the current user.

Complete any input parameters for the router activity.

Select to cause the system to check the operator's availability and substitution values before routing to a worklist.

Field

Description

Enter the name of the assignment as it appears on the Visio diagram and on the rectangle or tab at runtime.

Select a field value rule for the worklist display that describes the task that users perform to complete the assignment. . Click the pencil icon ( ) to review the field value rule or define a new field value rule. The SmartPrompt lists field value rules with an Applies To key part equal to the work type of the flow rule (or a parent class) and a Field Name key part of pyInstructions.

When you plan to localize the application using this rule, so the application can support users in various languages or locales, choose the text carefully and limit text length to 64 characters. A field value rule with this text as the final key part is needed for each locale. When practical, choose a caption already included in a language pack, to simplify later localization. See About the Localization wizard.

Identify one connector flow action.

Select to create an entry point for the assignment and allow user processing at runtime to begin or resume at this point in the flow. When selected, if this screen flow presents steps as tabs, at runtime a tab appears with the Name value as a label.

Leave cleared to indicate that users cannot return directly to this assignment; users may be able in some cases to reach it indirectly from an earlier assignment.

This check box appears only when you select the Entry Point? check box. Select to restrict users who at runtime are at this entry point to only entry points (on the breadcrumbs or tab display) for earlier steps in the flow.

Clear to allow users to select any entry point of the flow from this entry point. Users can click the breadcrumbs control or a tab to visit an earlier or later step.

For maximum user flexibility, leave this check box cleared if your flow accepts inputs in any order. However, this approach is typically not workable for flows that contain fork and decision shapes, or that have intermediate tasks that are not entry points.

Select to cause Process Commander to execute the Validate Rule rule and the After This Action... Run Activity activity (both on the Action tab of the Flow Action form) when a user at runtime clicks a screen flow tab or screen flow tree node to leave this assignment and start (or return to) a different assignment. The post-processing activity can compute additional property values and perform other processing.

If the option is not selected, the validate rule does not execute and the post-processing activity does not execute when the user clicks to leave the assignment.

As a best practice, check this option if the action has a non-blank Validate Rule or non-blank After This Action... Run Activity activity.
