Unload handler added for use with custom popups
Resolved in Pega Version 8.1.9
A memory leak seen in Microsoft Internet Explorer was traced to a custom script to close windows which bypassed window unload and continued to hold some objects in memory. This has been resolved by introducing a new file which will load only for popup harnesses and which registers the unload handler to remove the popup window references.

Check added for backwards compatibility with Case Type when rules
Resolved in Pega Version 8.1.7
After upgrade, the When rules present on case type rules (used for skipping stages or showing/hiding stage-wide or case-wide actions) were not executing at run time. This was traced to the introduction of the pySkipOrAllowType property in recent versions, and was only reproducible when the ApplicationRuleset was locked and after upgrade irrespective of whether the condition for when was true or false. To resolve this and enhance backwards capability, a check has been added for the SkipOrAllowType property being empty.

Local UUID cache will be updated when merge event is detected
Resolved in Pega Version 8.1.7
Cluster-related issues were seen in multiple production clusters. For some nodes in the cluster the Cluster Management screen showed all expected nodes with valid Node IDs displayed, and on other nodes the Cluster Management screen showed the node ID of itself, SERVER@localhost:5701. On an impacted node displaying the wrong ID, the Node Information landing page did not work and displayed the error "Unable to execute job on ." Multiple advanced agents running on nodes in the affected clusters, both with correct and incorrect IDs, also failed with a similar error "Unable to execute job on <node's job id>". This was traced to a merge performed after a split brain. To resolve this, the code has been updated to handle merge events: when the node UUID is changed as part of a split brain recovery, the local UUID cache will be updated when the merge event is detected.

Resolved stale reference error when swapping stages with drag and drop
Resolved in Pega Version 8.1.9
If user swapped stages (2nd stage to 1st stage) using drag and drop and then added a participant or role in the stage, a Pega blue screen appeared. This was traced to using a grid with reorder and an inner grid in the cell. On drag and drop, the grid reference object was stale and not in sync with the latest table. To resolve this, code has been added to reinitialize the inner grid on drag and drop.

Large report pagination should use "Previous and Next only"
Resolved in Pega Version 8.1.7
Some Report Definitions were getting timed out or facing gateway exceptions, primarily due to high time consumed by the DB Queries. Investigation showed the total result count process appeared to stop at the configured pyMaxRecords value as long as it was nonzero. This indicated the issue was related to changes made to fix the inaccurate behavior of the "Last" button in the responsive paginator which included removing logic that set pyMaxRecords to anything other than zero. To resolve this issue, those pagination changes have been reverted. The "Last" button should not be used when the paging mode is set to Numeric: in the case of large reports, the paging option should be set to "Previous and Next only".

Force order added to inner join when running a Rules Resolution filter
Resolved in Pega Version 8.1.7
After upgrade, D_getResolvedWorkStatuses was not loading properly due to a Report Definition that used a Filter by Rule Resolution option timing out on the SQL Server. When the Filter by Rule Resolution option is selected in RD, it will generate a rule resolution query with an inner join which can cause a time out on the SQL Server while it tries to find out the join order for tables with multiple joins. To resolve this, the SQL server will provide a Force order, merge inner join hint option by way of an added DSS reporting/useForceOrderHint. Additionally, reporting/useMergeHintForRRquery should be set on Pega-Reporting to set things up for using the Merge Inner join hint in the query.

Dirty check added to offer save/discard changes when closing tab
Resolved in Pega Version 8.1.7
With the out-of-the-box section enabled, performing a change in the form (changing a text value, selecting a option in a dropdown, etc.) and closing the case generated an unexpected alert indicating that the case was changed and the modifications were lost. This differs from the previous behavior of showing the section pyDirtyCheckConfirm which offered the opportunity to save the work. This was a missed use case and has been resolved by updating the system to perform a check for the dirty state when closing the interaction and show a modal dialog asking the user to choose either save/discard if dirty.

Improved upgrade handling for tables using classes with property references
Resolved in Pega Version 8.1.7
After upgrade, some page property values were blank and exposed database columns did not contain the values. Investigation showed that the reference properties did not have context and hence column population was not able to determine their value. To resolve this, instead of doing column population for all the columns, the system will identify classes that have property references and that are being optimized as part of upgrade process and maintain a list of specific columns to update.

Strategy handling updated for very large systems using IH summary
Resolved in Pega Version 8.1.9
When a Strategy in a Real-time dataflow used IH Summary on a system with more than 5000 groups for one eventKey, the message "Error retrieving aggregates from Cassandra KVS" intermittently appeared. Investigation showed that if the number of result rows was greater than the FETCH_SIZE (set to 5000), it meant another read to Cassandra was required and an exception was generated. To resolve this, updates have been made so that instead of returning maps, the system will return iterators and change them to map on the calling thread.

Port validation updated for redirect URI
Resolved in Pega Version 8.1.9
When an offline app for windows client was generated, trying to login via SSO resulted in the error "invalid redirect_uri". This was traced to the system validating the whole loopback redirection URL, e.g. "http://127.0.0.1:1234/redirection", including the port number. To enhance flexibility, an update has been made so that the port number will not be validated, allowing the client to establish it based on availability at the moment of the request to the authorization service. NOTE: As a best practice, a loopback URL should not be configured as a redirect URI. If a loopback URL is configured, then at run time the port number will not be validated, and the client application can use any available port on the system including ports that may not be intended for use.
