Data page definition reload made more robust
Resolved in Pega Version 8.6.4
The data page was intermittently being removed from the cache. This was traced to the use of a thread from ThreadContainer to reload the data page definition: a null thread could be returned if the request came from a master agent, which would then cause the definition reload to fail. This has been resolved by updating the system to use the current thread in context to reload the data page definition.

ClusterAndDBCleaner updated to with with Oracle query limits
Resolved in Pega Version 8.6.4
The pzClusterAndDBCleaner job scheduler was not able to cleanup data in pr_op_data session table due to the delete query formed to clean up this table throwing "ora-01795 maximum number of expressions in a list is 1000 oracle 19c" exception. This has been resolved by splitting requestor IDs into batches of 1000.

Fallback added for missing fileName in MultipartHTTPResponse
Resolved in Pega Version 8.6.4
Given a multipart/form-data response with multiple attachments, when there was no explicit fileName header provided for a body part, the engine skipped processing the part and no data was present on pyRequestAttachmentPage. This has been resolved by adding a fallback in HTTPClientUtils#handleMultipartHTTPResponse() so that if no fileName is present, the 'name' parameter of the Content-Disposition header field will be used.

Performance improvements for save-as
Resolved in Pega Version 8.8
Performance issues were seen when using save-as for rules such as Declare expression, When rules, activity, etc. This was traced to a very large number of extra database queries that were being executed while building the Declarative Cache. To resolve this, an update has been made so the queries used for the Declarative Cache will only be executed when required.

Added debug logging and exception recovery for unexpected data object
Resolved in Pega Version 8.8
When rules were complied in lower environment and deployed into production, they later became corrupted and system behavior changed. The error "Java generation failed: caught exception while expanding property pyGetCasePredictionsByClassName on page CurrentRecord" was generated. Investigation showed the auto-populate property pyGetCasePredictionsByClassName was attempting to get the metadata property "pzDataObjectParams": this was a string value in this scenario instead of the expected java object, and caused the exception. To resolve this, a debugger has been added which will check if the property is a java object or not. If it is not, the system will skip the processing and then display an error message with a stack trace.

Prconfig added to control declarative behavior during page merge/copy
Resolved in Pega Version 8.8
Declare-on change was getting triggered multiple times even though there was no change in the watched property. Investigation showed this happened when properties had the same value in source and target page. To resolve this, a prconfig has been added which may be used to disable declaratives while performing page merge operations for these properties. The setting name is clipboard/putAllKeepNew/doNotFireDeclaratives: when true, it will disable declaratives when there is no change in property value while performing page merge/copy operation with merge strategy PUTALL_KEEPNEW. The default value is false.

REST authentication settings use fully qualified name for resolution
Resolved in Pega Version 8.8
The application setting used in REST connectors for authentication was resolving to similarly-named rules instead of matching the exact name of the rule. This has been resolved by enhancing pzGetSettingID to use both parts of the fully qualified name (name and category) provided by the pzSettingsORA control when determining which setting from the report to return.
