Handling updated for validating properties with a FieldValue
Resolved in Pega Version 8.7
Running a report which included a property calculated by a Declare Expression generated an excessive number of log messages indicating "Error occurred while executing forward chaining on page 'pyReportContentPage.pxResults". Degraded system performance, stack overflow, and other similar issues were seen. This was traced to an infinite loop that resulted from a missed use case for a Report Definition with a Target property of a Declare Expression with FieldValue, and has been resolved by disabling autochain while validating properties with a FieldValue.

ServicePackage threads properly released
Resolved in Pega Version 8.7
After completing a system stress test, the requestor pool threads for the ServicePackage were not released. Investigation showed that the threads were waiting for Data Pages to be loaded in the background even though there was no background job corresponding to those data pages in the Async Services pool. This has been resolved by making an update to avoid removing the object handlers when the load-datapage finds that an entry exists with a NOT_STARTED state.

Handling added to StreamChangeTracker for non-String mode
Resolved in Pega Version 8.7
Incorrect StreamChangeTracker mode properties were being tracked for value changes. Investigation showed this was due to the StreamChangeTracker.trackValueChanges API tracking value changes on properties of mode page and page list, which resulted in logging a WrongModeException in the logs. This has been resolved by updating the behavior of the StreamChangeTracker.trackValueChanges API to return false when value change tracking is invoked for a property other than mode String.

Links to specifications persist appropriately
Resolved in Pega Version 8.7
When linking Rules to Specifications, check-ins of some unrelated rules deleted the link. Investigation showed the deletion happened in the pzHandleLinksPostCheckIn activity, and was caused by an empty parameter page name that caused pcInsKey to not have a value, so all links returned by "Obj-Browse" were later deleted. To resolve this, an update has been made to insure the "Pass current parameter page" option in step 2 of the Connect REST PostCheckIn activity is enabled so that the downstream activity pzHandleLinksPostCheckIn behaves as expected.

Case Archive updated to better prune email and attachment metadata
Resolved in Pega Version 8.7
After configuring pyPegaArchiver, pyPegaIndexer and pyPegaPurger to remove old cases, there were no records present in the pr_metadata table but the records related to Data-Corr-Email, Data-WorkAttach-File and Link-Attachment remained. As there is no harm in removing these entries because the system has already copied the reference to these attachments, the entry in pr_metadata can be removed without any issue. With this update, external and shared entries now get removed from pr_metadata table when a purge is performed, however they do not get removed from the target table.

Performance improvement for Application Save: Node Level Data Pages
Resolved in Pega Version 8.7
As part of new functionality introduced in 8.3, data types defined in the application record will be turned into data objects on Application save. As part of this process node level pages are invalidated and reloaded and there is an explicit commit that marks the Application record as dirty and sends any calls for the application record to the database for fresh records. In a multi-node environment, the number of queries to get the application record being saved became exponentially higher and performance impacts were seen. This has been resolved by updating the system to skip eager loading of the data page definition when an access rule or application definition is saved.

Index table correctly populates after migration
Resolved in Pega Version 8.7
After creating a product file with work instances, only some records were populating in the index-workpartyuri class through index rule. Investigation showed that if the IDs specified for the Work Range started with the same digits as were seen after the case prefix (e.g. W-1, W-1000, or W-22, W-2201) then only the indexes for cases that start with W-1 or W-22 were included in the export. This was traced to a step in AddPartyIndexWhenCondition where the EstimatedWorkPrefix local variable was calculated: the java step extracted anything that was the same from the start of the To and From range without taking into account the possibility that some digit characters after the "-" could be the same. To improve the accuracy of the prefix estimation, "-\d" will be used to make an educated guess.

Handling added for multi-file upload of duplicated files
Resolved in Pega Version 8.7
Attaching the same file multiple times during a single upload caused some of the duplicated files to not be included. The issue was not seen when attaching the same file multiple times but in different attempts. The exception "Can't continue with file attachment. FileData.xlsx is missing and might have been quarantined by anti-malware software" was logged. This was caused by the files being uploaded without updating filenames to have a unique ID, so multiple files with the same name were overwriting the previous file. This has been resolved by setting the appendUniqueIdToFileName parameter to true in the upload request so each copy of the filename is treated as an individual file.
