Unused DSS compiledExpressions now defaults to false
Resolved in Pega Version 8.4.6
After updating from Pega 8.2 to Pega 8.5, executing a test campaign failed with an error in logs. This occurred when running Distribution tests with "Include funnel analysis reports" checked, and was traced to the DSS setting "decision/strategy/ssaVM/compiledExpressions". As this was previously used to toggle a feature which is no longer in use, the default setting for this DSS has now been changed to false to resolve this issue.

Strategy execution queries tuned
Resolved in Pega Version 8.4.6
During Next Best Action strategy execution, interaction history summaries were queried multiple times for a single strategy execution. To improve this function, the isChanged query will now be executed once after system startup if there are no changes instead of being executed every time the Aggregates DataSet BBK is executed. If the same Aggregates query is made multiple times as part of a Strategy in a REST request (i.e. likely multiple ADM models in a MakeDecision call), only one Aggregates BBK call will be made.

Dataflow with report definition source repaired
Resolved in Pega Version 8.4.6
After update, data flows using a report definition dataset as source were throwing a null pointer exception. This was traced to previous work done around retry handling for Oracle queries where there were issues identifying the correct column types; that previous work has been reverted to resolve this null pointer exception, and further work will be done to refine the solution to the Oracle CLOB DatabaseException.

Performance improvements for stale thread warnings
Resolved in Pega Version 8.4.6
Stale thread warnings were causing performance issues during dataflow run execution. Stale thread/slow component warnings are added as part of the dataflow execution when a processing thread takes more than 5 minutes to process a single dataflow record. The stacktrace of the dataflow thread is added as part of the warning for debugging purposes, but in some scenarios the stacktrace can become very large. This has been resolved by removing the stacktraces from the warning, improving the query logic, and adding the run ID to the exception method to assist if there is an error.

Survey Complex Question Definition properly displayed
Resolved in Pega Version 8.4.6
Selecting any Complex Question to look at the definition displayed a blank screen. This was traced to an issue with the ruleformtabs properties for the layout group used by complex questions, and has been resolved by changing the Layout Group display type from "Default" to "Tab".

Improved Page compare for page groups
Resolved in Pega Version 8.4.6
Field level auditing on embedded properties sporadically did not report the "old" value when a property was modified even though the page was listed as "Modified". This has been resolved by adding logic to the pxComparePages algorithm to treat Lists and Groups differently. Now Page and Value Groups will use pxSubscript as the primary way to detect add and deletes.

Added logic to handle manual validate rule creation
Resolved in Pega Version 8.4.6
Manually creating a Validate rule with conditions and then opening the configure view with conditions caused the validation rule to be removed from the flow action rule along with the validation conditions in the validation rule referred in flowAction rule. This has been resolved by updating the logic in the Condition Builder to handle this use case.

Offline.Rulecache UI module capacity increased
Resolved in Pega Version 8.4.6
Clicking the save button on a modal window caused the application to freeze and all the buttons were disabled. This was traced to the pega.offline.rulecache UI module having a default hard limit of 500 rules. Once the hard limit was reached, the system intermittently silently refused caching additional rules depending on the amount of rules packaged or the order in which the rules are loaded to the cache. To resolve this, the system has been updated to only log a console warning once the maximum threshold is reached, allowing the application to operate normally and at the time inform about the potential impact of having too many rules in memory.
