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.

Keyboard shortcuts work in Decision Trees
Resolved in Pega Version 8.3.6
Keyboard short cuts in Decision Trees used to copy/paste by holding ctrl button in Decision Trees were not working. This was an unintended side effect related to changing non-auto grid to an auto-generated hierarchical table to make the Decision tree rule form multi-browser compatible, and has been resolved by adding cut/copy/paste/insert-after/insert-before functionality to the decision tree context menu.

Handling added for application which includes production ruleset
Resolved in Pega Version 8.3.6
When creating the Email channel or Webchat channel, the Text Analyzer and its respective class (Data-Decision-Request-MCP-WebChat-xxxxx) was being saved in the ruleset of the built-on application while there were rulesets open in the top application. This was a missed use case, and has been resolved byupdating the logic to account for the scenario where an application includes a production ruleset.

Logic updated to handle decision trees over 64k
Resolved in Pega Version 8.3.6
An exception was thrown when decision trees reached the 64K size limit. This has been resolved by modifying the logic in the DecisiontableMethodBody Rule-Utility-Function where the split size PropRowLimit is based on the number of columns.

Decision Trees refresh after updating a new row
Resolved in Pega Version 8.3.6
Updating a decision tree row did not display the updated data until after save and refresh. This was traced to the first row not meeting the condition for refresh on change because the first row was created as part of the decision tree creation, so the data was not persisted and the update was not registered as a change. This has been resolved by adding explicit handling for the first row to persist its expression string and show the data as entered.

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.
