OpenRuleAdvanced updated
Resolved in Pega Version 8.4
After upgrade, the Update Page and Append and Map to step in Data transform was generating the error "No Server connection while giving page name to Target and Source". This was traced to the OpenRuleAdvanced_OverLabel control, and investigation showed that a variable was not being resolved when invoking pzEncryptURLActionString. This has been resolved by updating OpenRuleAdvanced and reimplementing two parameters as well as moving the call of these variables to the beginning of the script. Security has also been improved by moving some of the encryption to SafeUrls.

Property setting corrected for On Join and Exclusion shapes in Expression Builder
Resolved in Pega Version 8.4
The properties for the defined page did not appear when using the type-ahead feature to select properties for the On Data Join and Exclusion shapes in Expression Builder.

Parameter page retained after strategy test case checkout

Tracer issues resolved for Google Chrome broswer
Resolved in Pega Version 8.4
Tracer was running in the background even after the tracer window was closed. Attempting to run a Tracer in this condition resulted in an error indicating the Tracer was being run by another operator and should be restarted, and in the Dev environment, attempting to start a Tracer once it was closed resulted in the message "Cannot launch multiple Tracer sessions for a requestor." Investigation found that the Tracer session was not being closed when the tracer window was closed because the browser specific method intended to do so was not being called. This was found to be an issue caused by the Google Chrome browser changing the signature of the method, and has been resolved by updating the method name in the TraceMain HTML rule.

Multi-nodes rebuild LibraryMetadata to ensure all Rule-Utility-Functions are present on change
Resolved in Pega Version 8.4
When performing a complete Application import into a clean installation, references to certain Rule-Utility-Functions went unresolved during the initial assembly. Investigation showed that after introducing a new Rule-Utility-Library or Rule-Utility-Function on one node in a cluster and then generating that, the other nodes in the cluster did not have the correct LibraryMetaDataCache for that Rule-Utility-Library.Therefore assemblies on those other nodes could be bad and throw a runtime UnresolvedAssemblyError. This has been resolved by modifying the way the Library subsystem processes the node changes events for Library Generation to ensure that each node completely rebuilds the LibraryMetadata for that Rule-Utility-Library so it contains all the Rule-Utility-Functions.

JMS push notification made more robust
Resolved in Pega Version 8.4
After creating a JMS Service to call pySendPushNotification from an activity, running it using User Context worked as expected but selecting initialize Service Context resulted in the Push notification silently failing in the context of JMS service. The JMS is used as a communication medium between legacy and Pega solutions. When the message arrives, Pega creates a new case and sends a push notification to the user, who has only 2 minutes to accept the case. Because of the urgency of timeliness in this situation, the push is sent directly from the context of the service rather than expend 30 seconds for agent processing. However, because the application was not always available to the pySendPushNotification activity (and further to API call), the push failed. In order to avoid this condition, the system has been modified to use the more widely available pxThread instead of Application when possible.

Catch block added to handle invalid FindAndUpdateElement clipboard data
Resolved in Pega Version 8.4
An exception was generated relating to "Unable to passivate page on thread '<savedwork>' . The following items were not serializable: [Property not serializable: "Declare_pyDisplay.pyDisplay(InteractionPortal).pyUIElements(3).pyParameters.activityParamPage" Class: "com.pega.pegarules.pub.runtime.ParameterPage." This was traced to invalid data in the clipboard, and has been resolved with the addition of a catch block in pzFindAndUpdateElement Rule-Utility-Function which will put an empty string in the clipboard whenever there is an invalid value in the 'Declare_pyDisplay.pyDisplay().pyUIElements().pyParameters' clipboard page.

Updated retry for context registraton
Resolved in Pega Version 8.4
The system was intermittently hanging after importing zipped files. Investigation showed that Batch threads were becoming stuck in AuthorizationContextManagerImpl.setSpecializations() due to a 'while' loop in setSpecializations that was seeking to register the new context. To resolve this, logic has been added which will try to register up to 10 times. If for any reason it can't register, the system will just return the unregister LAC. The check before deregister has also been enhanced and now will only deregister if the new context and the current context are different. It will not call register if the current context and the new context are the same.
