Fixed flow line distortion in Process Modeler
Resolved in Pega Version 7.1.9
When clicking through to a subprocess from a parent flow (by clicking the + sign in the blue subprocess shape), flow lines in the subprocess were shown in a distorted fashion. When opening the same flow in a separate tab (by right clicking the blue subprocess shape and selecting Open Flow) the flow lines were correctly painted. This was an issue caused by the different renderings of the flow depending on whether there was a click through to it (with the + on the parent flow?s subprocess shape), or the subflow was opened in a separate tab (with open Flow). After the Process Modeler saved and checked-in the flow, the connector lines were re-drawn in ways that were non-intuitive and hard to interpret due to the edge routing in PM being calculated off incorrect input data that was taking into account shapes that were not represented on the screen. To fix this, the system now ensures the edges are routed without taking into account any shapes not represented on the canvas.

Requestor token creation added for PRExternal authentication
Resolved in Pega Version 7.1.9
When using a PRExternal authentication scheme, the csrfsession requestor token was not created. This caused a heavy volume of INFO logging messages in production due to the null token. This authentication path has now been added and the token will be correctly created for use.

Improved performance for incorrect password handling
Resolved in Pega Version 7.1.9
When the operator entered the wrong password in the login screen, numerous "Stream Overwritten" alerts appeared the Alert log. There was no workflow problem involved, but the logging indicated that there was an additional unnecessary call being made to Stream Web-Login, and that unneeded call has been removed to improve system performance and remove the error being logged.

Fixed scrumboard intermittent failure
Resolved in Pega Version 7.1.9
After upgrading, it was seen that the scrumboard would intermittently fail to load, partially displaying and then hanging if the columns did not fit within the window boundaries due to the number of elements. This was traced to an error in the functionality that resizes parts of the scrumboard, and has been fixed.

Corrected validation error for Extract rule field length
Resolved in Pega Version 7.1.9
A validation error noting that the field length of the table was limited to 30 characters was occurring when trying to check in an Extract rule even if the field value had been shortened. While checking in the extract rule, a block of code in the Rule-Utility-Function validateTreeProperties was recomputing the pagelist's table name instead of using the one provided by the user. The Rule-Utility-Function validateTreeProperties function has been modified to fix the issue.

Update Handler will not run during migration
Resolved in Pega Version 8.4.1
Rolling restart of DataFlow, ADM ,VBD, and Util Tiers failed with a PENDING_JOINING error after an in-place upgrade. This was traced to the logic for the update timing: when nodes start after an upgrade from 7.x to 8.x they will migrate data flow runs. Migration happens on only one node, and while it's in progress the other nodes will wait until migration finishes before they come up. At this point the state of the data flow services will be 'PENDING JOINING'. The issue is that while migrating runs, the Data Flow Update Handler was triggered to validate whether there were nodes available on the service the run belongs to. This call can cause the corresponding data flow service to be initialized, but the call will be blocked since all services wait for the migration to end. This resulted in a deadlock which prevented all nodes from coming up successfully. To resolve this, the process has been updated to skip the update handler during migration to avoid triggering the initialization of client services that are waiting on the migration lock.

DDS service will not run Hazelcast check if external Cassandra is configured
Resolved in Pega Version 8.4.1
Services were not responding, and thread dumps seen in the logs indicated that a large number of threads were waiting for one to come back from getting the cluster state for a DSM process. Investigation showed that the threads were waiting for a Hazelcast response about the cluster state. However, since a Hazelcast call is not needed when Pega is configured with external Cassandra, the DDS Service code has been changed to not to check for candidate nodes if configured with external Cassandra cluster.

Corrected calculating propensities
Resolved in Pega Version 8.4.1
Several PMML models designed to compare the outcomes to a control dataset experienced an issue where the probability scores in Pega did not match the original control dataset. The PMML model was also tested using KNIME; those results matched Pega but not the original control dataset. Investigation showed that the JPMML evaluator contained outdated code, and the incorrect calculations have been resolved.
