Unit testing support for more rule types

Valid from Pega Version 8.3

You can now create unit tests for the following additional rule types. You can also create assertions to validate activity status. The expanded rule types for unit testing enable developers to more thoroughly perform regression testing of their application, thereby improving application quality.

  • Collection
  • Declare expression
  • Map value
  • Report definition

For more information about unit testing rules, see Pega unit test cases.

Upgrade impact

With the four new rule types, unit test execution and unit test compliance metrics will change. Reports on automated unit testing of the customer application decrease due to the increased pool of supported rules.

What steps are required to update the application to be compatible with this change?

After a successful upgrade, create Pega unit test cases for the newly supported rules to see updated and accurate unit test metrics.

Use Page-Change-Class method to change a Page class

Valid from Pega Version 8.3

With the release of Pega Platform™ 8.3, using the Property-Set method to change the Page class shows a guardrail warning. Use the Page-Change-Class method to change the Page class instead.

For more information about the Page-Change-Class method, see Changing the class of a page and Page-Change-Class method.

Simple associations for quickly joining classes

Valid from Pega Version 8.3

Associations now have a simple mode. Use a simple association to quickly and easily join a class to another class. The simple association defines a left join, using a foreign key in the source class and the class key in the target class. Use an advanced association for all other conditions. In addition, simple associations are drawn in the Visual data model reporting mode to visualize the relationships that are available for reporting.

Upgrade impact

The new simple mode draws a map of where all the classes defined in the application rule are drawn as nodes. Relationships between the nodes that are defined by relevant properties are drawn as lines linking the two classes. This feature only includes Case and Data classes that are defined on the Application rule form's Cases and Data tab. It also only includes relevant fields for those classes in order to define the relationships from one class to another.

What steps are required to update the application to be compatible with this change?

After a successful upgrade, add the data and case type classes to the application rule in Dev Studio to have the selected classes appear as a node. In addition, if you want a relationship to display as relevant, set the properties (of the class that defines that relationship) as relevant.

 

For more information, see Exploring the data model.

Association changes after upgrade

Valid from Pega Version 8.3

Associations now have a simple mode. Simple associations are those that join to only one class, use a left join, and have one filter condition to a class key in the target class. Existing associations that define a simple foreign key relationship are upgraded to simple associations when opened; all others are treated as advanced associations. All associations continue to work in reporting.

Making an association simple changes only one piece of metadata; all other data on the association rule is not affected.

Upgrade impact

The new simple mode draws a map of where all the classes defined in the application rule are drawn as nodes. Relationships between the nodes that are defined by relevant properties are drawn as lines linking the two classes. This feature only includes Case and Data classes that are defined on the Application rule form's Cases and Data tab. It also only includes relevant fields for those classes in order to define the relationships from one class to another. 

What steps are required to update the application to be compatible with this change?

After a successful upgrade, add the data and case type classes to the application rule in Dev Studio to have the selected classes appear as a node. In addition, if you want a relationship to display as relevant, set the properties (of the class that defines that relationship) as relevant.

Changes to URL format for Pega Web Mashup

Valid from Pega Version 8.3

The format of Pega Web Mashup URLs now supports multiple mashups on a single web page. The new URL format prevents a mashup from sharing cookies with another mashup.

If you want to include multiple mashups on a single web page and one of the mashups was created before 8.3, you must regenerate the mashup to reflect the new URL format.

For more information, see <link to help topic>.

Change tracking tab removed from declare expressions

Valid from Pega Version 8.3

To simplify the configuration of a declare expression, the Change tracking tab has been removed from the declare expression rule form. To use the Change tracking tab, on the declare expression rule form, click Actions > Use legacy expression.

For more information, see Supported and unsupported configurations in simplified declare expressions.

Upgrade impact

The declare expression rules have been moved from the pr4_rule table to the new pr4_rule_declare_expression table.

The upgrade can fail if you customize the pr4_rule table, such as increasing the length of an existing column.

After a successful upgrade, the declare expression rule form is simplified and lightweight pages support declare expressions.

What steps are required to update the application to be compatible with this change?

Read-only data pages by default are lightweight. You could also enable lightweight pages for:

Only simplified declare expressions are supported in lightweight pages. In simplified declare expressions, context-bound rules are not supported. However, a page context could be specified on the New or Save As form of declare expressions. For more information, see Declare Expression rules - Completing the New or Save As form.

Redirectguests mashup configuration has been removed

Valid from Pega Version 8.3

The authentication/redirectguests server configuration and data-pega-redirectguests attribute have been removed and are no longer required when you configure a mashup. This prevents you from needing to maintain multiple nodes to support some use cases that require the configuration value to be true and other uses cases that require the configuration value to be false.

For more information, see Configuring the Mashup channel.

Rules can no longer access Pega internal Java packages

Valid from Pega Version 8.4

You can no longer create rules that access Java packages that reference internal APIs (syntax com.pega.platform.*.internal*). This change does not affect rules that access Pega public API packages.

If you encounter issues when running existing rules that reference internal Pega APIs, contact Pega Support.

Upgrade impact

After an upgrade to 8.4 and later, clients can no longer save new or modified rules that access Pega internal APIs; existing rules that reference internal APIs can still be run but cannot be modified. 

What steps are required to update the application to be compatible with this change?

Following a software upgrade to 8.4 or later, clients can refactor existing rules into guardrail compliant rules. To find rules to refactor, run the validation tool from designer studio (Application > Tools > Validation) to identify what rules fail validation; failed rules that include the message "Test compilation failed : Illegal internal class reference : com.pega.internal.XYZ" can updated to reference appropriate APIs.

WSDL generation error prevents invocation of SOAP services

Valid from Pega Version 8.4.2

Status

A Known Issue was introduced in the 8.4.2 Pega Platform patch release, which impacts both upgrades and new installations of that version.

Description

Due to changes introduced in the SOAP functionality for the case-mismatch error in SR-D98509/INC-119725, the WSDL is being generated for SOAP services with an incorrectly-capitalized element, which prevents the service from being invoked.  The element should be “name” instead of “Name”.

Workaround

Clients must perform the following workaround after they define a new SOAP connector in Pega Platform:

  1. To download the WSDL from Pega Platform:
    1. After using the SOAP Wizard (Dev Studio > Configure > Integration > Services > Service Wizard) the WSDL URL is shown at the bottom right of the Dev Studio screen.
    2. Click the URL to display the XML.
    3. Save the WSDL file to your local system.
  2. In the text editor of your choice, modify "Name" to "name" in every <element “name” = … > tag in the WDSL.
  3. Save your changes to the local file.
  4. To reload the WSDL into Pega Platform:
    1. In Dev Studio, open the Configure menu.
    2. Select Integration > Connectors > Create SOAP Integration.
    3. In the New SOAP integration wizard, select Upload WSDL from File.
    4. Complete the upload using the wizard prompts.

This is a design-time issue, not a run-time issue; therefore, clients only have to perform this workaround process once. Existing SOAP services should not be impacted; however, if clients modify an existing SOAP service definition by re-running the wizard, clients must reapply the workaround for Pega Platform to recognize the SOAP definition changes.  

Resolution

This issue will be addressed in the Pega Platform Patch Release 8.4.3.  Clients who upgrade to that version or later should not see this issue.

Search and Reporting does not index large items

Valid from Pega Version 8.5

When using the Search and Reporting (SRS) microservice in Pega Platform™ 8.5, you might encounter problems with indexing large out-of-the-box rules. The issue is not visible in Queue Processors, but you can access logs to verify which items the system does not index.
