Handling added for null requiredskillcount on assignment
Resolved in Pega Version 8.2.7
If the property pxRequiredSkillCount was blank on an assignment when moved to a workbasket, it was never presented for Get Next Work. To resolve this, handling has been added which will change the null to 0 so the assignment is properly queued.

Corrected approval step task message
Resolved in Pega Version 8.2.7
When a case progressed to the approval step, the task name did not properly appear as part of the "Please approve or reject this" message. In another scenario, a portal which supported locale switching was not translating "Please approve or reject this" when the locale was switched, but instead displayed the message in the original language. Investigation traced this to the pzInstructionsForApproval data transform storing the localized field value, causing it to persist inappropriately. This has been resolved.

Busy indicator appears when uploading via Select
Resolved in Pega Version 8.2.7
After update, the “loading symbol” (busy indicator) was not appearing while uploading large attachments using the Select button. This was a missed use case in recent changes to related to AsyncUpload, and has been resolved.

Updated retry logic for S3 AddAttachmentFromEmail
Resolved in Pega Version 8.2.7
When using the AddAttachmentFromEmail activity with S3 repositories, performing an obj-save on the data-workattach-file page executes a deferred save while also saving the file into the repository. if the data was inserted into S3 successfully but encountered an issue when saving the related data-work-attach-file page, the system was trying to call the save operation again. This tried to insert the duplicate attachment again to S3, causing an error on that side of the process. To resolve this, the duplicate Obj-Save functionality in AddAttachmentFromMail Activity has been removed.

Completed onChange will reset FileInput value to null
Resolved in Pega Version 8.2.7
When attaching a file using the "Select File" button, it was not possible to attach the same file after deleting it. Re-attaching the file worked as expected when using Drag and Drop. Investigation showed that the onchange event occurred only when the value of an element was changed, so in this case trying to attach the same file did not change the value of the element and did not fire the onchange. To resolve this, the value of FileInput in pzMultiFilePath Control will be set to null at the end of the onChange event so that an onChange event will be triggered next time even if the same file is added.

Modifications to getFunctionalServiceNodes process
Resolved in Pega Version 8.2.7
The count of the Interaction History write related threads was increasing rapidly and a stack trace indicated "waiting on condition" and "java.lang.Thread.State: WAITING (parking)" errors. Investigation showed that this was due to getFunctionalServiceNodes using Hazelcast to determine node status by making a service request on an installation with a very large number of nodes, causing thread locking. To resolve this, the implementation has been updated to avoid calling getFunctionalServiceNodes on save of Interaction History, instead using Cassandra and only calling getFunctionalServiceNodes on the master node, not on all nodes.

Behavior made consistent between SSA and legacy engines
Resolved in Pega Version 8.2.7
There was a behavioral disparity between the legacy execution engine and the SSA engine where the latter was not creating a new page when the index was one above the size of the page list. This has now been corrected in order to make the SSA behavior fully backward compatible with the legacy engine, i.e. a new blank page will be added to the list if the index is one above the size of the list.

Updated precondition checks for Tumbling Time data in event strategies
Resolved in Pega Version 8.2.7
Tumbling Time data keys in event strategies were not being properly executed when certain window configurations were used. This was has been resolved by turning off the optimalization of Cassandra reads for small windows when window size is not known upfront and set dynamically (set size by property). In addition, an issue with Cassandra timeouts after the dataflow run had been running for several months has been resolved by adding a 'time to live' value for tumbling time windows, and event strategies has been switched to use leveled compaction by default.

Improved management for table pr_log_dataflow_events
Resolved in Pega Version 8.2.7
The Lifecycle event table was sometimes growing too large. This additional strain of database transaction volume caused poor performance on the Dataflow tier and lead to cluster instability and time-consuming cluster restarts. Due to problems in one of the Pulse tasks, the Pulse thread was not processing single case metrics properly and causing the unbounded queue for single case to grow. This has been addressed by switching to a fixed queue size, which is configurable with the DSS: dnode/single_case_queue_size. The default value of the DSS is 4000, and if changed a system restart is required. An error will be logged each 1000 queue misses, and metrics will be dropped if the queue is full. In addition, the Pulse task frequency has been improved and managed to prevent interference with other Pulse tasks and will be triggered only if a run is system-paused for a long interval. Rebalances now have a failsafe if something unexpected happens during the Pausing of the run, and If the cluster becomes unstable, the life cycle events logs may be disabled with dataflow/run/events/persist .

Updated COUNT logic for strategies with ssavm set to true
Resolved in Pega Version 8.2.7
An error was seen when attempting to save a strategy after setting ssavm to true, indicating an issue in the “COUNT” method in Group By shape. Since the source field is not used and does not need to be evaluated here, the system has been updated to ignore the source field if the operation is COUNT.
