Server node cache refresh will use remote execution timeout
Resolved in Pega Version 8.2.4
A campaign was failing due to VBD remote ping timeout with a stacktrace that indicated a StageException. Investigation showed that when the cluster is heavily loaded, calls to the remote execution API could time out. If this occurred when the VBD client was refreshing its cache of VBD server nodes, then the insert failed and the error was propagated up the calling data flow. To resolve this, the system will use the remote execution timeout when refreshing node cache, extend the timeout to 60 seconds, and ensure timeouts are retried during inserts.

Resolved Transfer to Queue duplicate assignments
Resolved in Pega Version 8.2.4
The Transfer to a Queue option was creating duplicate assignments after accepting the Chat. Once the chat was accepted, an instance was created\maintained in both Assign-Workbasket and Assign-Worklist tables. This happened after adding the "Transfers" queue to an Agent; if that queue was not added, the transfer to a queue option gave an error to the Agent receiving\accepting the chat. The Work-.ReassignDefaults activity is an extension that was customized in the Pega-DecisionManager ruleset for a certain use case in revision management. The customization is no longer required and has become redundant and has therefore been removed to resolve this issue.

Response Strategy works for predictive models
Resolved in Pega Version 8.2.4
After implementing the response strategy for the predictive model and capturing the response, "Refresh Data" in the monitor tab of the predictive model still showed no response captured. As a result, it was not possible to analyze the performance of the model or use it for reporting. This was traced to recent work done so that Response processing now references the factory against a new table. However, the entries in this table were not created for predictive models, causing responses to not be processed. This has been resolved by adding predictive models to the event processor and ensure the functions are using the new factory initializer.

VBD insert process updated for better retry handling
Resolved in Pega Version 8.2.4
When restarting Data Flow and VBD nodes, the VBD client can encounter some exceptions indicating components in the stack are temporarily unavailable. In most cases the VBD client retries, but there are some cases where it did not and data flow failures occurred. To resolve this, the code has been updated to remove logging of the VBD cluster status during a retry, and the retry duration has been made configurable.

Compliation error resolved for editing complex offers
Resolved in Pega Version 8.2.4
The following error was logged while trying to edit offers: "com.pega.pegarules.pub.generator.FirstUseAssemblerException: Failed to compile generated Java, com.pegarules.generated.html_section.ra_stream_pyeditelement." Research showed the code for the static initializer was exceeding the 65535 byte limit, causing the java compilation of the pyEditElement section to fail for a decision data rule. This was due to the pyEditElement section for a decision data rule being circumstanced: the assembler architecture of circumstanced section rules generated and added code for all the versions of a circumstanced section. Hence, if the section referenced a lot of properties and it existed in multiple ruleset(s)/ruleset versions, the java compilation for the section rule failed. To correct this, the integration of the pyEditElement section with decision data rules has been revised and enhanced, and a function and utility have been provided to call the function to clean up the old and redundant pyEditElement sections for a given decision data rule.
