Handling added for identical property and page names in test case recording
Resolved in Pega Version 8.5.3
When trying to record a test case, the error "WrongModeException: The property PostProsSnapOfWorkpage.Name was of mode String while com.pega.pegarules.data.internal.clipboard.ClipboardPropertyImpl.getPageValue() was expecting Page mode" was generated. This was an edge case caused by property and page names being the same on the "PostProsSanpOfWorkPage" page, and has been resolved by accessing the page with the full path so it has the proper prefix.

Upgrade compatibility enhanced for Pega-ConditionBuilder ruleset
Resolved in Pega Version 8.5.3
In Pega v8.2.5, the Pega-ConditionBuilder ruleset was added as part of the PegaMarketing application. When these enhancements were promoted to a platform ruleset beginning with Pega v8.4, the function names were modified with PZ/PX prefixes due to the corresponding validation standards in place for rules created in platform rulesets. Unfortunately, this introduced an upgrade impact. Due to the function name change, strategies failed when attempting to evaluate the functions configured in the filter component. Eg: @string.ContainsIgnoreCase function is part of the Pega-ConditionBuilder ruleset, which was not available. To resolve this, the following function aliases have been created in this release:ContainsIgnoreCase StartsWithIgnoreCase EndsWithIgnoreCase CompareDateTimeToSymbolicDate

Updated Time Zone dropdown control
Resolved in Pega Version 8.5.3
The RF_Timezonelist control was deprecated in Pega v8.4 and withdrawn in Pega v8.5 and a replacement datapage was provided to give the same list of time zones. Unfortunately, some references were not corrected to point to the replacement, causing an issue with custom functions that were attempting to set the time zone on an OperatorID calendar instance in order to calculate goal and deadline properties before setting the SLA. The work has been reviewed and updated to ensure all referencing rules are now correctly replacing the RF_Timezonelist with a dropdown sourcing the data page.

Unescaping characters implemented for expressions
Resolved in Pega Version 8.3.6, Resolved in Pega Version 8.4.4, Resolved in Pega Version 8.5.3, Resolved in Pega Version 8.6
An issue where expression builder statements were evaluated differently at runtime than at testing has been resolved. Pega Platform expressions with String literals(that is, sequences of characters enclosed in quotation marks) now unescape characters in strategy shapes such as Set Property or Filter.

Adaptive models update correctly
Resolved in Pega Version 8.5.4
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.

Materialization uses time limit boundary for query
Resolved in Pega Version 8.5.4
After turning on Materialization for pyIHSummary and OfferOutcomesForPast45Days datasets, an SQL query was taking an excessive amount of time and causing multiple alerts in the logs. Investigation traced the issue to database partitioning, specifically that running a query where the pyOutcomeTime range spanned multiple partitions was causing the indexes for all partitions in the range to be opened. To resolve this, the query has been updated with a DSS to support a partition size of min(pxOutcomeTime) to limit the time range to querying day by day, or hour by hour, or any other chronology unit specified. If there are no records for the current limit, then it will look at the next partition. This should prevent the query from needing to open more than 1 or 2 partitions.

Hazelcast remote execution not called from synchronized context
Resolved in Pega Version 8.5.4
After navigating to the Admin Studio portal to view the nodes, the portal was temporarily freezing. Investigation of the thread dump revealed this was caused by a DDS pulse sending a remote execution call to all nodes to update logger settings even though the site was not using DDS. This has been resolved by updating the system to avoid calling Hazelcast remote execution from a synchronized context.

Duplicate key exception resolved for adaptive model
Resolved in Pega Version 8.5.4
During the model snapshot update, a DuplicateKeyException was generated while trying to insert a record in to the predictor table. This did not affect the model's learning, but did appear ion the model monitoring report. This was traced to a local scenario of having the same outcome values defined on the model with different cases (Accept and accept). All predictors used in an Adaptive model are inserted into the model monitoring tables as a part of the monitoring job: because the monitoring tables are not case sensitive, this lead to a unique constraint exception since there were multiple IH predictors with the same name. To resolve this, validation has been added which will skip adding duplicates from new responses.

Upgraded Apache UIMA Ruta libraries to resolve memory leak
Resolved in Pega Version 8.5.4
A memory leak issue that resulted in a reboot being needed every few days was traced to the class org.apache.uima.ruta.rule.RuleMatch. This has been resolved by upgrading the Apache UIMA Ruta libraries to v2.8.1. A high level of exception logging may be seen under high loads due to annotations in the standard Ruta scripts; this will not impact execution and further work will resolve this in a future release.

Corrected unreleased database connections
Resolved in Pega Version 8.5.4
When using a custom activity that calls Dataset-execute on a database table dataset, the DSS Pega-Engine.prconfig/classmap/usemergestatement/default was set to false and the prepared statement for a database table dataset was failing. Upon the failure, an exception was generated that prevented the database connection from being released. This has been corrected.
