Context set for progressive scroll load of dynamic layout
Resolved in Pega Version 8.4.4
When setting pagination as 'Progressively load on scroll' for a repeating dynamic layout in a section with pagelist as the source, scrolling resulted in a null pointer exception and no further scrolling was possible. The issue was not seen when 'Progressively scroll on user action' was used. Investigation showed the activity Reload Section was failing because of the failure in the pre-processing activity, and this has been resolved by setting the correct context before making the pagination call.

Report filter error message persists on the screen
Resolved in Pega Version 8.8
When attempting to use an invalid report filter such as "past 14 days" when that timeframe was not available, the error message appeared briefly and then disappeared. Investigation showed the runReport activity pzResolveCopyFilters activity was called and caught the “Invalid value” exception, however the system continued to proceed so the error message did not persist in the screen. This has been resolved by adding a jump condition to step 2 of pzResolveCopyFilters on StepStatusFail to preserve the error message.

Handling added for Oracle "NUMERIC" type
Resolved in Pega Version 8.8
When a product rule was created in an environment using Oracle, importing the product into the cloud environment with database table schema changes resulted in errors. This was traced to a change in Oracle's JDBC driver which was reporting Number as a JDBC "NUMERIC" type instead of the previous "DECIMAL". Pega uses the NUMBER data type and expected a type=DECIMAL for an Oracle number, causing the errors. This has been resolved by adding a check for flex numbers if column is NUMERIC.

Timeout for loading predictors made configurable
Resolved in Pega Version 8.4.4
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.

AvailableProperties cleanup added after save
Resolved in Pega Version 8.4.4
The Report filter value auto-complete was displaying an incorrect list of values. This was traced to pyAvailableProperties not being cleaned up after being created and used in a prior process, and has been resolved by ensuring pyAvailableProperties is removed on save so it can be cleanly built when needed.

Dirty dialog flag reset added for custom modals
Resolved in Pega Version 8.4.4
When a discard button in a custom Cosmos modal dirty dialog was clicked, pega.u.d.isDirtyDialogOpen was not reset to false. This caused the modal dialog to not be shown the next time. This has been resolved by modifying pzpega_ui_doc_dirtyhandling to support this dirty handling discard use case.

Client side validation works with Reference page property
Resolved in Pega Version 8.4.4
A reference page property in a 'when' rule was not evaluating properly for checking a Date field when client side validation or Client side template UI was checked on the Harness level. This was traced to pyRequired being boolean: the boolean being compared to a string false value yielded a wrong comparison, leading to the wrong validation type required. To resolve this, the system will use the === comparator to compare boolean false in datetime to remove the required validator.

Handling added for external Kafka authorization exception
Resolved in Pega Version 8.8
When using external Kafka for stream service, the dataflow was failing with the error 'QueueProcessorDataSubscriberException' when topic create permission was missing. As a workaround, the topics could be pre-created, though a "Topic already exists" warning was generated. To resolve this, the cluster-wide right that a producer needs, IdempotentWrite, has been added. For more information please refer to the link https://docs.confluent.io/platform/current/kafka/authorization.html

Email listener update for Microsoft Exchange server
Resolved in Pega Version 8.4.4
After upgrade, TooManyObjectsOpenedException/MapiExceptionSessionLimit errors were seen when starting the email listener. Investigation showed that when the listener was started, two sessions were getting opened and then not closed properly. This was a method originally intended to allow the system to re-use the session to minimize performance overhead, but it is not well-suited for use with Microsoft exchange server as the Exchange server is unable to cleanup idle sessions. As a result, too many MAPI sessions were opened and led to an authentication exception while opening additional sessions. To resolve this, an update has been made so the system will close the session while the listener sleeps. This stop, restart and graceful shutdown scenario for single threaded email listener scenarios will create a new session every time and close it properly.

Unneeded AUC error percentage calculation removed for better system performance
Resolved in Pega Version 8.4.4
When generating snapshots of the ADM models, an inefficiency in the metric calculation for the AUC error percentage caused an excessive amount of memory to be allocated which could cause slowdown or require a system reboot. This has been resolved by removing the problematic AUC error percentage calculation as it is not used in the UI.
