OptimizeForLargeResults flag set in BasicListSpecification to avoid OOM
Resolved in Pega Version 8.4.5
As soon as dedicated indexing started for a data type, the JVM heap occupation went beyond 99 and eventually caused a system crash due to an out of memory error. This was traced to the use of the BasicListSpecification API for retrieving results from the database always having the autocommit mode on, which loaded all instances for indexing into memory and interfered with PostgreSQL's cursors (query encapsulation). This has been resolved by adding an OptimizeForLargeResults flag that will be set to on in the BasicListSpecification activity before fetching the keys from the database.

Out of memory condition resolved for BIX extraction
Resolved in Pega Version 8.4.5
A node was going down automatically during execution of a BIX Extract rule when working with old objects. Investigation showed this was related to an out of memory error: the work object had nested page lists, and when one of the page lists contained a propertylist which contained more records, the system was trying to add entries to the LinkedList if any properties were missing the reference during extraction. Because LinkedList allowed duplicates, it filled with enough errors to cause the out of memory condition. To resolve this, LinkedList has been replaced with LinkedHasSet, which does not allow duplicates.

Logic updated for exporting customized multi-column report definition
Resolved in Pega Version 8.4.5
While attempting to perform an export to Excel for the results of a report definition which had two custom functions for two columns, the error "PRRuntimeException: Section 'pzRDExportWrapper' execution error on page '' of class 'Rule-Obj-Report-Definition'. : The Reference .pyTextValue(2) is not valid. " was logged. The export worked if either one of the columns was removed or if "Display values across columns" in the column settings was unchecked. This has been resolved by updating the logic in PivotTableDataGridGenerator for rowheaders to handle using DisplayValuesacrossColumns with FunctionAliases when not checked on in sequence.

Summary Report collapsible sections made accessible
Resolved in Pega Version 8.4.5
In order to improve accessibility, the rules 'RRDataSummaryGeneration' and 'pzDisplayGroupNodeVertical' have been updated so the clickable expand icons in summary reports will append the value of the current group when setting the text "Click to expand or collapse". This will allow JAWS to uniquely identify exactly what will be expanded or collapsed.

BLOB decryption API updated for greater flexibility
Resolved in Pega Version 8.4.5
A BIX extraction issue occurred after the class had enabled BLOB Encryption. The errors indicated the BLOB had been persisted in an incorrect stage, causing the extraction of the single item to never complete even though some CSV file was created. This was traced to the API used to read the encrypted BLOB, DatabaseUtilsCommonImpl.getStreamBytes, which had the limitation of decrypting only when a Site-specific cipher existed. To resolve this, the system has been modified to use a different API which works for all encryption modes, PageDatabaseMapperImpl.getStreamBytes().

Zero value parameter handling added to Trend Reporting
Resolved in Pega Version 8.4.5
After converting the Summary Views to a Report Definition, the Chart reporting functionality was not working in the Report Definition drill-down reports; whole records present were being fetched instead of only the graph chart count. Investigation showed that one of the parameters in the FilterBy was missing, and that pxSLAAgeTimeliness used 0 instead of null, causing the system to consider all records. This has been resolved by using the "reporting/useNullForUnqualifiedRecords" DSS setting to handle the 0 value and ensure all parameters are present.

Report title displayed for empty widget charts
Resolved in Pega Version 8.4.5
Per design if there is no data to be rendered in the chart from a report added in a Widget in any portal, a static image is displayed saying "No Data to Display". However, if there were multiple reports in the Widget it caused confusion on which report was not being displayed because the image did not show the title of the report. To resolve this, an enhancement has been added to modify pzRRChartDiv to display the report Title even when there is no data in it.

Local time used for report filters
Resolved in Pega Version 8.4.5
The date format in the filter condition of the report was being displayed in GMT format rather than the Local time Format. This has been corrected.

Added handling for missing deleted/report shortcut for drilldown
Resolved in Pega Version 8.4.5
Whenever “Report Details” for a drilldown report without category was clicked, a Flow Action Error was generated. This was due to a missing Report shortcut normally stored in the Report Definition, and has been resolved by modifying pzPreProcessReportDetails to handle the edge case of a shortcut not present/deleted for a drill-down report.
