Timeout for loading predictors made configurable
Resolved in Pega Version 8.3.6
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.

Adaptive models update correctly
Resolved in Pega Version 8.3.6
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.

Locking added to avoid null pointer error for auto-populate property
Resolved in Pega Version 8.3.6
After configuring the auto populate property "OrgProduct" which referred to a data page, the system experiencing heavy load led to the property not getting properly initialized. This resulted in a WrongModeException and NullPointerException. To resolve this, the system has been updated to lock the requestor when Queue Processors execute their activity. This will prevent race conditions and concurrent modifications if other threads are accessing the same requestor.

Duplicate key exception resolved for adaptive model
Resolved in Pega Version 8.3.6
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.

ML model continue tag error changed to debug logging
Resolved in Pega Version 8.3.6
Log entries were seen indicating "The continue tag is found without a start tag for window Line1 1234567890 in text". This appeared to be coming from the MLCommand java class. Investigation showed this occurred when the ML model believed a portion of the text (token) was a continuation of the entity because it has not found the starting part of the entity. This situation is not currently treated as a valid output, so an update has been made to change the logging level from error to debug for this case.

Null check added for step page
Resolved in Pega Version 8.3.6
After creating and adding new Access Roles and application 'Access When' to the privileges instead of Production level, during run time the error "runtime.IndeterminateConditionalException: Trying to evaluate Rule-Access-When conditions L:IsProdAccess when there is no page to evaluate them against" appeared for the specific privileges. This was traced to a missed use case where the system falls back to the step page if the page for evaluating the 'when' condition is null, which did not account for scenarios where the step page can be null. To resolve this, a null check has been added which will fetch the primary page if the step page for the access 'when' condition is null.

Improved disconnected requestor cleanup for FieldService
Resolved in Pega Version 8.3.6
A large number of requestors from FieldService with the status as 'Disconnected' were accumulating and causing performance issues. This was traced to the requestors not getting passivated due to users not logging out and new requestors being created for the same users next time, and was caused by the value of the DSS Initialization/PersistRequestor being set as "OnTimeout". When the DSS prconfig/timeout/browser/default is not configured, the default browser requestor timeout is 60 minutes. In this scenario, requestors were not passivating as the requestor passivation timeout was set to the refresh token lifetime for mobile users, which was very large and overwrote the DSS value. This has been resolved by removing the code which set the passivation timeout to the OAuth2 refresh token lifetime.

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.
