Unneeded class name filter removed from GetRelevantPropertiesForDataType
Resolved in Pega Version 8.4.1
Given one class with a set of properties and another class inherited from the first class containing a relevant records set for class 2, then a new harness did not show the base class fields. Investigation showed that the fields present in the parent class and marked relevant in the case were not being fetched due to pzGetRelevantPropertiesForDataType having a class name filter along with filter by rule resolution. To resolve this, the class name filter has been removed as it is not required due to the report already filtering by rule resolution and relevant class through a join.

Check added to apply values of newAssignPage.pxFormName
Resolved in Pega Version 8.4.1
After upgrade, trying to open existing assignments resulted in a different harness being opened. This was traced to changes in how the property newAssignPage.pxFormName was used, and has been resolved by checking whether the harnesspurpose is dynamic before setting the pxFormName. If formname is already present, the system will proceed with picking the harness from the shape.

Approved flow rule image unlocked
Resolved in Pega Version 8.4.1
When the Approval Required check box was enabled for rulesets (i.e another person with access to this work queue should approve changes to the rules), a rule which was approved was unlocked and moved back to the original ruleset as expected, but the binary image associated with the flow rule remained locked and any other user other than the one who previously checked in the rule was denied access with a "check out failed" error. This locking error has been resolved by modifying the Rule-Obj-Flow!CleanUp activity to set Param.IgnoreInstanceLockedBy = true.

Corrected row focus for deleting in App Studio case model
Resolved in Pega Version 8.4.1
When attempting to delete a row of properties from the 2nd page of the data model of a case type while using App Studio, clicking on the delete icon brought up a dialog box asking for confirmation for deletion but at the same time the screen went back to the first page of the data model instead of remaining on the second page. Because of this, clicking on the OK button to confirm the deletion caused a random property from the first page to be deleted instead of the targeted row of the second page as expected. This was due to the refresh being triggered immediately within overlay UI actions, and has been resolved by updating the first trash icon action set for the section pzExpressFieldActions to be a modal instead of an overlay when launching local action.

Update Handler will not run during migration
Resolved in Pega Version 8.4.1
Rolling restart of DataFlow, ADM ,VBD, and Util Tiers failed with a PENDING_JOINING error after an in-place upgrade. This was traced to the logic for the update timing: when nodes start after an upgrade from 7.x to 8.x they will migrate data flow runs. Migration happens on only one node, and while it's in progress the other nodes will wait until migration finishes before they come up. At this point the state of the data flow services will be 'PENDING JOINING'. The issue is that while migrating runs, the Data Flow Update Handler was triggered to validate whether there were nodes available on the service the run belongs to. This call can cause the corresponding data flow service to be initialized, but the call will be blocked since all services wait for the migration to end. This resulted in a deadlock which prevented all nodes from coming up successfully. To resolve this, the process has been updated to skip the update handler during migration to avoid triggering the initialization of client services that are waiting on the migration lock.

DDS service will not run Hazelcast check if external Cassandra is configured
Resolved in Pega Version 8.4.1
Services were not responding, and thread dumps seen in the logs indicated that a large number of threads were waiting for one to come back from getting the cluster state for a DSM process. Investigation showed that the threads were waiting for a Hazelcast response about the cluster state. However, since a Hazelcast call is not needed when Pega is configured with external Cassandra, the DDS Service code has been changed to not to check for candidate nodes if configured with external Cassandra cluster.

Corrected calculating propensities
Resolved in Pega Version 8.4.1
Several PMML models designed to compare the outcomes to a control dataset experienced an issue where the probability scores in Pega did not match the original control dataset. The PMML model was also tested using KNIME; those results matched Pega but not the original control dataset. Investigation showed that the JPMML evaluator contained outdated code, and the incorrect calculations have been resolved.

DataSet preview will use date instead of datetime
Resolved in Pega Version 8.4.1
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.

Added tokenizer for KeyWord-Based Topic Detection phrases
Resolved in Pega Version 8.4.1
KeyWord-Based Topic Detection was not Working for "Enrollment/Re-Enrollment" as a word, for example a categorization model with the text 'This is an email related to Enrollment/Re-Enrollment'. To facilitate this use, a tokenizer has been added to break 'should',' must', and 'and' words into components for a taxonomy match.
