INC-143121 · Issue 610732

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.

INC-160331 · Issue 628710

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.

SR-69015 · Issue 619995

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.

SR-D89428 · Issue 550391

Data Flow StartTime uses locale timezone

Resolved in Pega Version 8.3.3

The start time of the dataflow was displayed in GMT instead of the operator locale timezone. This has been corrected.

SR-D77157 · Issue 544471

DataSet preview will use date instead of datetime

Resolved in Pega Version 8.3.3

While using a DataSet preview functionality, the date appeared as reduced by one day. This has been resolved by parsing date as 'date' instead of 'datetime' to avoid issues with timezone interactions.

SR-D87709 · Issue 552397

Default context check added for saving adaptive model with locked rulesets

Resolved in Pega Version 8.3.3

When updating an adaptive model rule in Prediction Studio, the error message "No unlocked Rulesets/Versions found that are valid for this record. Unlock at least one Ruleset/Version that can contain records of this type." appeared when clicking Save. This occurred when a branch was used in the default context of the Prediction Studio settings. Although there was a workaround to use Dev Studio to Save As the adaptive model rule to the required branch, this has been resolved by adding a check for default context and then saving the model there if it is mentioned.

SR-D89012 · Issue 550799

DelegatedRules refresh icon made accessible

Resolved in Pega Version 8.3.3

When using Accessibility, the refresh icon in pzDelegatedRules was being read as "Link". This has been corrected by adding text for the refresh icon.
