Added support for imported rules to populate bixreportpage
Resolved in Pega Version 8.4.1
Extract rules were not holding the filter criteria after upgrade while performing save-as (for the first time) of the imported rules from the previous version. Criteria were held when the filters were created in the new version. This was caused by BIX extracts created in earlier releases (7.x) not having bixreportpage included. When an environment was upgraded to 8.x versions, opening an extract required the bixreportpage to be populated with Report Definition metadata including the filters defined in the actual extract. Although the filters from the original extract were converted to filters that are acceptable by ReportDefinition, they were not being added to bixreportpage on opening the extract. To resolve this, the system has been updated to copy the filters back to bixreportpage on opening the extract in the upgraded environment.

Obj-Browse will retrieve more than 50 records
Resolved in Pega Version 8.4.1
After performing multiple skims, a newly added property was not retrieved when an Obj-Browse was performed. In Obj-Browse action, when a class is mapped to an external table and does not contain BLOB column pzpvstream, in a specific case where pxObjClass value is a reference to a parameter, a list of properties mapped to the class explicitly by querying pr4_rule_property table using NativeSQL is fetched. This call by default returns only 50 records: in cases where there are more than 50 properties for an external class, some of the properties from the obj-browse response mapping are therefore missed. To resolve this, the limit of 50 records has been removed from this NativeSQL call.

Corrected Agent schedule time conversion
Resolved in Pega Version 8.4.1
After upgrade, a mismatch between the agent configuration and schedule was seen, causing an agent scheduled at 6PM Europe/London time to execute at 6AM Europe/London instead. Analysis of the Agent schedule rule showed that if the pyStartAmPm property was empty, the internal code miscalculated the AM_PM string as AM. That meant that if an agent was configured with 24 hour clock format and was set to run at 18:00 hrs, it executed at 6AM. The workaround for this issue involved resaving the agent, triggering the data transform pzSetStartAmPm to correct the field pyStartAmPm, but the issue has been corrected by adding handling for the pyStartAmPm == "" corner case.

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.

Properties persist after revision import
Resolved in Pega Version 8.4.1
"When properties were added to a form, they sometimes disappeared after revision import even though the properties always remained visible in a strategy. Investigation showed that the Form changes made in a DD rule were not properly updated in the pyEditElement section. To correct this, logic has been added to handle the form changes in the DD in the following activities:Data-Rule-Summary.pyMergePropositions Data-Rule-Summary.pyRemoveDDRules Data-Rule-Summary.pyWithdrawDDChanges Data-Rule-Summary.pyRemoveRestoreDDRule"
