Data flow stability improvements
Resolved in Pega Version 8.6.4
All nodes were showing as active and running in the cluster, including background, stream, web nodes, but the queue processor would not start. Log entries indicated "IllegalStateException: Invalid run transition found [PENDING_NODES->COMPLETED] on run [DF_OutboundPreProcessing_SMS] by [EventDescription{originator=CheckNodeAvailabilityTask, reason=Restoring previous state." Due to this, all dataflows were moved to queued state. As soon as the corrupted dataflow was deleted the other dataflows were resumed. To resolve this, data flow stability improvements have been added along with better handling of runs in Queued state.

Addressed performance issues for classless DSMClipboardPage
Resolved in Pega Version 8.6.4
The DSMClipboardPage implementation handles Page Group access as a classless page (i.e. pxObjClass = ""), creating potential performance issues in implementations where the page group is used with a very large number of distinct AccountIDs in a short period. This has been resolved by updating the system to not cache keys for page group classless page.

Refresh added to limit commit log partition size
Resolved in Pega Version 8.6.4
Issues were seen on DDS nodes, including slowness and randomly dropping out and being replaced by new nodes. WARN messages in Cassandra logs reported issues relating to a large partition size of adm_response_commit_log_date_tiered table. Investigation showed the large partition size (over 10GB) was causing frequent C* query timeouts due to scanning a large number of tombstones, resulting in node terminations. This has been resolved with an update which will limit the commit log partition size by refreshing the NID every set interval.

Additional logging and executor work for Adaptive Decision Manager
Resolved in Pega Version 8.6.4
The Adaptive Decision Manager Pulse operation stopped running on some of the ADM nodes, causing an impact on the model update. To address this, some additional protections have been added for pulse operations running in a scheduled executor, and ERROR logging has been enabled.

Added handling for FieldValue issue during Excel export
Resolved in Pega Version 8.6.4
After upgrade from Pega 7 to Pega 8, the export to Excel function for business-rules kept and maintained via Decision-Tables created a file that Excel could not open. This was traced to a function call in the Results tab and the Return Actions in the decision table which caused an issue with the generated Excel to be used for editing. To resolve this, any allowed values will have quotation marks removed before the vales are passed to the export.

Added special character handling for DecisionTable column-label
Resolved in Pega Version 8.6.4
The label of a decision-table column was being appended to the original decision-table return-value. The column label and comparator were handled differently for columns containing special characters (+, -, *,...), causing the data after the special character to be trimmed and appended to the row output value. This has been resolved by adding handling for special characters so the output and the label are rendered properly.

Enhanced ruleset validation for portal creation
Resolved in Pega Version 8.6.4
Attempting to create a new portal (web channel) from the app studio using the Creation Wizard with "Branch development preferences" enabled resulted in the error message "No valid rulesets in application preferences". Investigation showed this occurred due to CPM-Portal being specified in the application as the UI class: when attempting to create the portal, the system was evaluating the class against ruleset candidates. The class was not visible to the rulesets in the stack and thus the portal could not be created. This has been resolved by adding validation on UI pages, Int and Data classes in the application to ensure that they exist in user rulesets, and by adding an allowance for classes to exist only in branched rulesets and not the base ruleset during check if the ruleset is present in application stack.

Updated AttachmentPreview control for Account Manager Access Group
Resolved in Pega Version 8.6.4
When using the Account Manager Access group as the default and only access group on a profile, attempting to render a PDF on the click of a link did not work as expected. The render-on-click worked as expected when logged in as the Author and the application was switched to Account Manager. This has been resolved by registering the activity pzAppStorageOkToAttachFile in the pzAttachmentPreview control.
