Resolved Intermittent Access Group Issue for GetBundleEventDecisionDetails

Resolved in Pega Version 8.5.2

When using a REST service that calls the GetBundleEventDecisionDetails activity and dataflow to send the treatment in multiple channels, intermittent access issue related errors appeared while running the activity in logs for multiple customers. This was traced to a missed use case for authentication, and has been resolved.

Support added for expression in strategy scorecards

Resolved in Pega Version 8.5.2

When invoking REST against a dataflow that had a strategy containing a scorecard that used an expression and the "Include model explanations option" was enabled in the Strategy configuration, the system failed with the error "PropertyValueInvalid .pxMaxScore Cannot cast the value (unknown) to double". This was traced to the Scorecard explanations failing during serialization when an expression was used, and has been corrected.

VBD performance improvements

Resolved in Pega Version 8.5.2

Performance issues were seen when running a decision funnel simulation. As part of the simulation, a VBD collection was created on the fly to store the metrics and linked to the simulation. Before each insert, which happened in batches of 500 records, there was a check if such collection exists. This check was required in earlier versions as the process relied on the VBD service being running, and the run would fail otherwise. Recently, VBD handling became more resilient and was updated to allow inserts even if the VBD server is down. If the VBD service is stopped before the simulation is completed, the simulation will continue writing records. When the VBD service starts again, it reads the backlog, and the simulation displays the final results. To adapt to this resiliency and improve performance, the system has been updated so that the VBD collection is not created and checked before the insert call, but only when the simulation is run or scheduled.

Strategy Simulation Runs made more resilient

Resolved in Pega Version 8.5.2

Intermittently, a decision funnel simulation would fail with particular strategy logic or a particular StrategyTracker would not contain the results for all components so the system would not be able to calculate input SRs. Handling has now been added to make the simulations more resilient so they will not fail with a null pointer error due to incomplete strategy inputs.

INC-144864 · Issue 599146

Unneeded AUC error percentage calculation removed for better system performance

Resolved in Pega Version 8.5.2

When generating snapshots of the ADM models, an inefficiency in the metric calculation for the AUC error percentage caused an excessive amount of memory to be allocated which could cause slowdown or require a system reboot. This has been resolved by removing the problematic AUC error percentage calculation as it is not used in the UI.

INC-148006 · Issue 605581

Enhancements added for very heavy use of strategy decision logic

Resolved in Pega Version 8.5.2

Recent updates were made to improve memory performance for scenarios where a single request primary page had tens of thousands of pages under an embedded pagelist property and the decision logic involved a strategy running on all the pages in that page list. To further improve performance, the array iterator has been modified and a DSS has been added that makes the threshold (50) in SSAExecutionContextIteratorFactory tunable.

INC-150854 · Issue 608368

Logic optimization disabled in offers

Resolved in Pega Version 8.5.2

Offers that should not be eligible to customers were passing through even though the offer was narrowed down to using “OR” conditions in the Engagement policies. This was traced to the logic optimization ignoring precedence, and has been resolved by disabling the optimization.

INC-128923 · Issue 594159

Cross-site scripting security update

Resolved in Pega Version 8.5.2

Cross-site scripting protections have been added to OpenNoteDetails.

INC-132590 · Issue 590492

Exported Excel from Decision Table wraps correctly

Resolved in Pega Version 8.5.2

After upgrade, entries were displayed in a single line on exporting a decision table to Excel despite WrapText cell formatting being set. This was traced to the WrapText cell formatting set under the UpdateGridCells() function being overridden inside an addDataFormat() function callas part of DecisionTableWorkBookConverter.java. This has been resolved by adding the new function "setWorkAreaCellStyles" and calling it after generateWorkbook() function call of super class (AbstractWorkBookConverter.java).

INC-136186 · Issue 592968

JAWS reads the name of the field/instructions

Resolved in Pega Version 8.5.2

JAWS was not reading the name of the field/instructions in a work group. This has been corrected.
