Enhanced Expression Builder for certain rule types

For certain rule types, several enhancements to the Expression Builder help you to efficiently build expressions in a user-friendly environment. Enhancements include:

• The ability to use single-line or multi-line comments to explain the purpose of the expression.
• Formatting, such as tab characters and carriage returns, that is preserved the next time you open the Expression Builder after closing it.
• Real-time validation of expressions so that you receive immediate feedback about the syntax in your expression.
• The ability to test the input value of a property for a portion or all of the expression.

These enhancements apply to the Expression Builder for the following types of rules:

• Data Transform
• When
• Map Value
• Decision Tree
• Decision Table
• Strategy

For more information, see Expression Builder enhancements for certain rule types.

Pega Composite Gateway not required for Pega Web Mashup

The Pega Composite Gateway servlet (prgateway.rar file) is no longer required for Pega Web Mashup gadgets. You can now use web mashups without deploying the Gateway. Support for the Gateway will continue, but it is a best practice not to use it for the Pega Web Mashup in Pega 7.2.1 and later versions.

Extract marker file not created at startup

The extract marker file (PegaRULES_Extract_Marker.txt) is not created at startup, because the rule utility libraries no longer need it. If you used to use the extract marker file to clear the static content file-based cache, to look up lists, or to control starting activities with web nodes, you can delete the contents of the PegaRULES temporary directory instead.

The UpdateAdaptiveModels agent causes an exception after Pega 7.2 to 7.2.1 upgrade

After the Pega 7 Platform is upgraded from version 7.2 to 7.2.1, the log files might show an error that is caused by the UpdateAdaptiveModels agent. This agent is enabled by default and is responsible for updating scoring models in the Pega 7 Platform. If you use adaptive models in your solution, you can avoid this error by configuring the Adaptive Decision Manager service. If you do not use adaptive models, disable the UpdateAdaptiveModels agent.

For more information, see Configuring the Adaptive Decision Manager service and Pega-DecisionEngine agents.

Reconfiguration of the Adaptive Decision Manager service after upgrade to Pega 7.2.1

After you upgrade the Pega 7 Platform to version 7.2.1, you need to reconfigure the Adaptive Decision Manager service. Beginning with Pega 7.2.1, the Adaptive Decision Management (ADM) service is native to the Pega 7 Platform and is supported by the Decision data node infrastructure.

For more information, see Services landing page.

Upgrade/update fails if PostGIS is applied to PegaRULES or PegaDATA schema

If you use the PostGIS extension to a PostgreSQL database, upgrading or updating the Pega 7 Platform fails if the extension has been applied to either the PegaRULES or PegaDATA schema. PostGIS can be applied to any other schema.

Email listeners no longer copy the email subject text to the email body

As of Pega^® 7.2.1, email listeners no longer copy the email subject text to the email body when the body is empty. If your customer application expects text in the body of the email, the application might fail. You can configure email listeners to copy the subject text to the body by using the following Dynamic System Setting:

Owning Ruleset: Pega-IntSvcs

Purpose: email/copyBodyNoContent

Value: true

For more information, see Creating Dynamic System Settings.

Pega Survey documentation refers to deprecated field

The documentation for Pega^® Survey refers to the Answer Layout field on the Complex Question form, but this field is no longer supported. For more information about the question layout formats that Pega Survey supports, see Pega Survey.
