Mobile features deprecated in 8.4

Valid from Pega Version 8.4

Following the introduction of new functionalities for mobile apps, some features are reaching end of life. To avoid additional effort during updates to future releases, do not use deprecated features.

In the 8.4 release, the following features are no longer recommended:

  • Mobile Client 7 is now deprecated and planned for removal in 8.5. Use Pega Infinity Mobile Client to meet the mobile needs of your business.
  • The Reuse existing web portal functionality is deprecated and planned for removal in 8.5. For improved app performance and more efficient development, use the mobile app builder in the mobile channel. Also, you must convert existing projects to use separate channels for mobile and web portals before upgrading to 8.5.

In addition, the Pega Mobile Express app has been removed from app stores and replaced with the Pega Mobile Preview app.

Changes to the architecture of the Data Flow service

Valid from Pega Version 8.4

In Pega Platform™ 8.4, the architecture of batch and real-time data flows uses improved node handling to increase the stability of data flow runs. As a result, there are fewer interactions with the database and between the nodes, resulting in increased resilience of the Data Flow service.

If you upgrade from a previous version of Pega Plaftorm, see the following list for an overview of the changes in the behavior of the Data Flow service compared to previous versions:

Responsiveness

Nodes no longer communicate and trigger each other, but run periodic tasks instead. As such, triggering a new run does not cause the service nodes to immediately start the run. Instead, the run starts a few seconds later. The same applies to user actions such as stopping, starting, and updating the run. The system also processes topology changes as periodic tasks, so it might take a few minutes for new nodes to join runs, or for partitions to redistribute when a node leaves a run.

Updates to lifecycle actions

To make lifecycle actions more intuitive, the Stop action consolidates both the Stop and Pause actions. The Start action consolidates both the Resume and Start actions.

You can resume or restart stopped and failed runs with the Start and Restart actions. The Start action is only available for resumable runs and continues the run from where it stopped. The Restart action causes the run to process from the beginning. Completed runs can only be restarted. If a run completes with failures, you can restart it from the beginning, or process only the errors by using the Reprocess failures action.

Starting a run

New data flow runs have the Initializing status, and start automatically. You no longer need to manually start a new run, so the New status is now removed.

If there are no nodes available to process a run, the run gets the Queued status and waits for an available node.

Triggering pre- and post-activities

The system now triggers pre-activities on a random service node, rather than on the node that triggered the run.

The system triggers post-activities only for runs that complete, fail, or complete with failures. If you manually stop a run with the Stop action, the post-activity does not trigger. However, restarting the run with the Restart action triggers first the post-activity, and then the pre-activity.

You can no longer choose to run pre- and post-activities on all nodes.

Selecting a node fail policy

For resumable runs, you can no longer select a node fail policy. If a node fails, the partitions assigned to that node automatically continue the run on different nodes.

For non-resumable runs, you can choose to restart the partitions assigned to the failed node on different nodes, or to fail the partitions assigned to the failed node.

No service nodes and active runs

If the last data flow node for an in-progress run fails, the run remains in the In Progress state, even if no processing takes place. This behavior results from the fact that data flow architecture now prevents unrelated nodes from affecting runs.

Source field not displaying in data transform

Valid from Pega Version 7.1.4

On the Data Transform rule form when using the Update Page action, if the Relation value is updated to “with values from”, the Source field will not be displayed.

(Note that for existing data transforms where the Source field has already been completed, this situation should not occur.)

Workaround

  1. Below is a data transform that has been configured to use Update Page.

  2. If a user were to choose an alternate source by updating the ‘with values from’ Relation value, they would not be prompted to provide a page name in the Source field.

  3. At this point, to be able to enter the Source page value, the user has to save the rule, which results in an error because the source page value is blank. This causes the field to appear.

  4. Once the field has appeared, the Source page value can be provided, and the form can be saved successfully.

Automated Unit Testing is unavailable

Valid from Pega Version 7.1.1

Automated Unit Testing (AUT) is unavailable in 7.1.1 - 7.1.5.

Starting in 7.1.6, users can access AUT features from supported browser versions of IE.

Privilege required for Recent Explorer

Valid from Pega Version 7.1.1

Users with custom roles defined must add the pxUpdateRecents privilege to see work in the Recent Items Explorer. 

Use standard Developer portal

Valid from Pega Version 7.1.1

Customized versions of the Developer portal rely on legacy components and are not supported.

To avoid backwards compatibility issues, update your access group to point to the standard Developer portal prior to upgrade.

Top-level (named) pages may no longer be classless

Valid from Pega Version 7.1.1

Newly created top-level (named) pages may no longer be classless or have a blank pxObjClass property. This change can affect applications upgrading from versions prior to Pega 7 to the latest version, especially when:

  • Application logic relies on a blank value in the pxObjClass property.
  • An activity assumes a new top-level page is classless and explicitly sets pxObjClass in a Property-Set step.
  • A data transform assumes a new top-level page is classless and explicitly sets pxObjClass using a Set action.

To avoid application failures, remove or update any logic that expects a blank pxObjClass. Where possible, use the new engine API that finds a page by both name and class:

findPageWithException(PageName, ClassName);

Activities and data transforms continue to create a top-level page when one does not exist. The class name is now derived from the Pages and Classes tab.

IE8 limits expansion features

Valid from Pega Version 7.1.1

Internet Explorer 8 (IE8) does not support CSS media queries, which are used by re-expansion features in the Designer Studio. IE8 users with low screen resolution (800 x 600) and a small window size may find that the explorer area in the Designer Studio collapses but cannot re-expand. 

As a work around, access the Designer Studio from another supported browser version and use the recommended, minimum screen resolution width of 1280 pixels.

All tabs are accessible on delegated rule forms

Valid from Pega Version 7.1.1

Delegates can now access all tabs in a delegated rule form.

You can continue to customize the development experience for delegated users, such as line managers, who may not require the full set of rule form options. For example, you can prevent users from adding new nodes on the Decision Tree form or using the expression builder on the Map Value form. All users, including delegated users, can remove these restrictions if they hold a rule-editing privilege.

For more details on this process and a list of commonly delegated rules, see How to delegate a rule.

Email approval and instantiation not supported on multitenant systems

Valid from Pega Version 7.2.1

The Enable email approval check box appears on the General tab of an approval step in Case Designer in multitenant systems. It also appears on the Approval shape in Designer Studio. In addition, in Designer Studio, the Settings tab in Case Designer displays the option to configure email instantiation. However, because configuring email listeners is not supported on multitenant systems, you cannot enable email approval or email instantiation.
