INC-138501 · Issue 592286

Added VBD support for CSRF token setting

Resolved in Pega Version 8.4.4

Attempting to open any VBD reports in the marketing portal for a simulation test caused the user to be logged out. Investigation showed that this happened when CSRF token check was enabled in System > Settings > Cross-Site Request Forgery, and was caused by the planner not passing the CSRF tokens in its Ajax calls. To resolve this, handling for the CSRF tokens has been added to the necessary Ajax calls.

INC-139574 · Issue 606143

Exception handling added for dataflow rule assembly

Resolved in Pega Version 8.4.4

A Blue Screen error was coming up in the Customer Service Web Chat Application after an agent accepted the incoming chat request and sent messages in the chatbox in the Interaction portal. This has been resolved by adding handling for exceptions that occur when inlining templates during dataflow rule assembly, when inlining templates, we weren't handling exceptions properly.

INC-140821 · Issue 600750

Resolved Intermittent Access Group Issue for GetBundleEventDecisionDetails

Resolved in Pega Version 8.4.4

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.

INC-142084 · Issue 599877

Support added for expression in strategy scorecards

Resolved in Pega Version 8.4.4

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.

INC-143121 · Issue 610734

Timeout for loading predictors made configurable

Resolved in Pega Version 8.4.4

When using an extremely large number of predictors, the Report definition pzADMPredictorsFilter was suffering timeouts due to the time for loading predictors from the database exceeding the time threshold allowed. This has been resolved by marking the rule as editable to allow custom setting of the threshold according to need.

INC-143441 · Issue 608898

Strategy Simulation Runs made more resilient

Resolved in Pega Version 8.4.4

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 599147

Unneeded AUC error percentage calculation removed for better system performance

Resolved in Pega Version 8.4.4

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 605583

Enhancements added for very heavy use of strategy decision logic

Resolved in Pega Version 8.4.4

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-148899 · Issue 615703

Adaptive models update correctly

Resolved in Pega Version 8.4.4

Some models had the recorded responses column updated, but the models (number of Positive, Negative and Processed Responses) were not updated. Investigation showed that deleting the modelRuleConfiguration through the stateManager/client did not delete modelFactories related to the configuration. If a new configuration came in with a different algorithm, the update issue occurred. This has been resolved by reseting the configuration according to its factory in that specific case.

INC-151037 · Issue 609625

Enhanced ADM diagnostic logging

Resolved in Pega Version 8.4.4

Diagnostic logging enhancements have been added in order to better identify issues related to ADM models not being created or where learning is impacted.
