SR-D37163 · Issue 505477

Corrected Decision Data import filter behavior

Resolved in Pega Version 8.2.4

After upgrade, if a Decision data import referred another component to filter out the import, it did not work. This has been corrected.

SR-D12733 · Issue 488666

Code fragment removed to eliminate Fortify false positive

Resolved in Pega Version 8.2.4

A code remnant related to Boolean.getBoolean(..) in Rule-Declare testConsistency was causing a false positive in a Fortify scan. This piece of code is obselete and is not used anywhere, and has been removed.

Filter added to ensure correct context for proposition strategy rules

Resolved in Pega Version 8.2.4

Given two applications (ex App1 and App2) hosted on the same domain where App2 was built on App1, trying to create a strategy rule in App1 and do a test run strategy using the propositional data component which internally uses App2 propositions generated the error: Failed to find a 'RULE-DECISION-DECISIONPARAMETERS' with the name 'GROUP_2'. There were 1 rules with this name in the rulebase, but none matched this request." Investigation showed the strategy was using the PropositionNoCacheUtils and PropositionTools java classes to load the propositions during run time. In these classes, the group classes were browsed from the db irrespective of the application context, causing the strategy run to fail as it was not able to access the decision data rules in other applications which shared the same SR class as the current application. To resolve this, a filter has been added to the PropositionNoCacheUtils and PropositionTools java classes to filter out the groups that are not in the current application context.

Kafka producer message size made configurable

Resolved in Pega Version 8.2.4

Kafka producer was using a default max message size setting of 1.3Mb while the Kafka broker max message size was set to 5Mb. This caused large processing queues to eventually throw errors indicating a scheduler.JobExecutionException related to "There was a problem saving an instance of class System-Message-QueueProcessor-DelayedItem". To correct this, a producer message size configuration option has been added along with additional logging for the KafkaSaveOperation.

SR-D41730 · Issue 508143

TTL value correctly passed for Adaptive Event store

Resolved in Pega Version 8.2.4

The ADM table was growing due to the Time to Live (TTL) for entries in the Adaptive Event Store not being propagated to clean them out. This was traced to the TTL field on the data flow not being checked, causing the TTL value to be supplied as zero so there was no expiration. This has been corrected.

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.

SR-D38415 · Issue 507995

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.

SR-D40833 · Issue 506792

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.

SR-D31103 · Issue 502978

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: " 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.
