URL encryption modified for ShowAllOperators
Resolved in Pega Version 8.5
In the control ShowAllOperators the call to pzEncryptURLActionString was introduced to encrypt URLs to avoid hijacking. The content of the URL relied on the pxRequestor.pxWorkGroup property which was resolved using pega:reference tags. This approach worked in versions below 8.x, but in higher versions the tags were not resolved at runtime and results were not displayed. To resolve this, the requestorWorkGroup will be treated as string and passed as parameter instead of using pega:reference tags.

FetchApplicationLogo modified to Filter by rule resolution
Resolved in Pega Version 8.5
It was observed that the Report Definition rule "pzFetchApplicationLogo", referenced by Activity rule "pzLoadApplicationLogo", always returned the older version of the Binary File "webwb • pyapp-logo • svg" because it had been set to retrieve a maximum of one record and in this case the results were sorted in an order where the oldest record was at the top. As the Report Definition did not indicate any sorting, most DBMS were returning the results in no particular or predictable order. To resolve this, "Filter by rule resolution" has now been enabled for RD pzFetchApplicationLogo.

Stale WorkSearchPreference data cleared when switching apps
Resolved in Pega Version 8.5
The D_pyWorkSearchPreferences data page data was not refreshing while switching between apps, causing stale data to be populated under the case search dropdown for all the applications after switching the application from one to another. This has been resolved by removing the D_pyWorkSearchPreferences data page as part of pzProcessApplicationSwitch.

TemplateButton field correctly set read-only
Resolved in Pega Version 8.5
When a control was added to a section using the DX API, a pyTemplateButton field was added to the XML definition of the section with read-only set to 'false'. This has been corrected so the pyTemplate Button field does not allow input.

Completed onChange will reset FileInput value to null
Resolved in Pega Version 8.5
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.

Cleanup enhanced for long pyEditElement names
Resolved in Pega Version 8.5
A pyEditElement error relating to decision data was seen multiple times in a stack trace. Research showed that while the utility worked as expected for decision data rules with names of less than 30 characters, the pyEditElement section was truncated the name for the decision data. This meant that decision data with the name SampleIssueandSampleGroupTwosalkdjkightntbmkblffvfvfv would be saved as SampleIssueandSampleGroupT for the pyEditElement section. Because of this, the utility failed the match and did not clean up the pyEditElement section. To resolve this, the cleanup utility has been updated to handle pyEditElement sections of decision data with longer names. Additional logging has also been added to improve debugging.

Real time processing picks up correct datetime for Capture Response records
Resolved in Pega Version 8.5
A Realtime Data flow for the Capture Response flow was configured with a strategy shape set to load previous decisions within the past 7 days. Once this Realtime DF was started, attempting to Capture Response for decisions made after that startup timepoint did not work. This was traced to the InteractionID being written with global properties for the datetimes, and has been resolved by making those datetime properties local so the start and end time are not cached and the time range is calculated based on "now”.

Handling added for prolonged Heartbeat Update Queries
Resolved in Pega Version 8.5
After restart, the pyFTSIncrementalIndexer queue size had hundreds of thousands of entries even though it was empty prior to the restart. Investigation traced this to a job scheduler that checked all the database connections everyday at 1 EST by using a list that contained some connections which did not exist. Checking those invalid connections caused other update queries to queue and wait, resulting in the update heartbeat query taking longer than its default beat. This caused a Split Brain issue wherein other nodes considered the long-executing node to be dead and triggered a rebalance while the node itself continued to execute partitions thinking that it was healthy. This caused duplicate processing of records. To resolve this, a fail safe has been added: while updating heartbeat in Service Registry, nodes will enter safe mode when the update query is taking longer than the default beat.

ADM out-of-sync corrected for multi-datacenter Cassandra cluster
Resolved in Pega Version 8.5
After setting up the multi-datacenter configuration for a Cassandra cluster that consisted of six nodes in datacenter 1 and three nodes in datacenter 2, failover testing revealed a mismatch in the number of ADM models stored in each datacenter. The mismatch was observed mostly in the number of records present in the "adm_scoringmodel" and "adm_response_commit_log_date_tiered" tables. When Cassandra nodes are down, the other nodes in the cluster will store hints (records to be written) for the down nodes. When these nodes come back online the hints are replayed to those nodes and the data is written. Hints are written for 3 hours, so if a node come back up within 3 hours data is recovered and repairs are not required. The gc_grace_seconds for the above tables that were getting out of sync across the two datacenters was set to zero seconds. The "gc_grace_seconds" attribute is not just used as the time for removal of tombstones, it's also used to set the TTL for records written to the system.hints table. That meant that when the hints were written for the ADM tables for the nodes that were down, they were immediately expired since it was set to 0 and not played back when the terminated nodes restarted and joined the cluster. This has been resolved with this fix for all customers new to this release. Existing customers already on v7.3 or higher will need to complete the local change detailed below: Connect to the Cassandra cluster using cqlsh in the Pega Cassandra distribution and then run ALTER TABLE adm_commitlog.adm_response_commit_log_date_tiered WITH gc_grace_seconds = 86400; to change the relevant setting from zero to the equivalent of one day - the same length of time that the data in the table lives for. This will mean that any hints written can still be used to replay data to another node while the data itself is alive. It does also mean, however, that, given a constant load, a day's worth of expired ADM event data in the table will always be present on the disk, as the tombstones can now not be cleaned up for a day.

Updated COUNT logic for strategies with ssavm set to true
Resolved in Pega Version 8.5
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.
