Support for validations in Declare Expression rules
Valid from Pega Version 8.5
Pega Platform™ now correctly evaluates validations on target properties in Declare Expression rules. As a result, any validations defined on properties that have Declare Expression rules in previous releases, now work correctly.
Upgrade impact
Any unintended validations on properties that have configured Declare Expression rules, both default and user-defined, might cause issues in an application upon saving work objects and data objects that refer to Declare Expression rules.
What steps are required to update the application to be compatible with this change?
If you experience issues when saving objects, debug your application by setting the declareexp/target/validation/disable dynamic system setting to true. If your application works correctly after the change, it means that validations on Declare Expressions cause the issues. For your application to work correctly, analyze the log files and remove any unintended validations.
For more information, see Declare Expression rules.
Upgraded selected third-party JAR files to support Pega Platform functionalities
Valid from Pega Version 8.6
Pega Platform™ 8.6 now provides upgraded versions of the JAR files that support various functionalities within the Platform, such as generating documents or PPTX files.
Upgrade impact
If you have custom implementations and use any classes from the upgraded JAR files directly in your code or through JAR APIs, after your upgrade to Pega Platform 8.6, your application might experience unexpected run-time behavior if the upgraded JAR version lacks any elements from the previous version. For example, custom implementations can typically include activities, functions, or non-autogenerated sections. Unexpected run-time behavior might also occur when you use a third-party library that has dependencies on the upgraded JAR files. If you use only default Pega Platform functionalities without any customizations, the JAR files continue to work correctly without any additional actions.
What steps are required to update the application to be compatible with this change?
If you have any JAR customizations, ensure that you test the upgraded JAR files for compatibility and upgrade impact. The following table lists the upgraded JAR files that might impact your application:
