Resolved classcast exception with assembled HTML controls
Resolved in Pega Version 8.4.5
A classcast exception was being generated on login. Investigation showed the Static Assembler was unexpectedly using a different Assembler to assemble the Html control rule. Standard behavior is that StreamBuilderAssembler assembles controls of type StreamBuilder and ControlAssemblerForVTable assembles controls of type ControlBuilder. In this case, static assembly for HTML controls using VTable was performed using StreamBuilderAssembler, causing a classcast exception when using VTable because the instance of the generated.html class was incorrectly inheriting from StreamBuilder (the parent class of ControlBuilder) instead of ControlBuilder which is the specified interface in the generated.html Java code. This has been resolved by updating the system to skip rules of type 'Rule-HTML-Property'(control) during Static Assembly.

Configuration added for extending queue processor timeout
Resolved in Pega Version 8.4.5
Alerts for queue processor (QP) items which took more than 15 minutes to run could result in the system marking the node as 'unhealthy'. In environments with Pega Health Check enabled, this would shut down the node gracefully. It was not possible to change this default as it was hardcoded. In order to support systems that may have custom processes that run beyond 15 minutes, a a new setting has been exposed that allows configuration of the interval after which a node with long-running queue processor is marked as unhealthy and is restarted. By default this remains 900000 milliseconds / 900 seconds / 15 minutes, but it may be adjusted up to 24 hours to avoid premature node shutdown. The stale thread detection mechanism will take that setting into account and use the provided value or default to 15 minutes if the value was not provided. In addition, the threshold's units in the UI have been changed from ms to seconds.

InsID will be derived from handle if null for upgrade
Resolved in Pega Version 8.4.5
Upgrade from Pega 7.2.x to Pega 8.4.x failed with a null pointer exception in the “Upgrade Context” target. This was traced to a rule where the pxInsID was null. To resolve this, an update has been made to derive the InsID from handle when needed.

Delayed JS/DF initialization failures will trigger alert
Resolved in Pega Version 8.4.5
In order to ensure better cluster monitoring, a PEGA0102 alert has been added for job registration failure that will be triggered if there are startup issues. The logging will include the JOB_NAME for improved troubleshooting.

Agent restart made more resilient
Resolved in Pega Version 8.4.5
During a timeout outage, agents intermittently encountered a NoClassDefFound error and were disabled. After the database connection was restored, the agents were not automatically restarting. This has been resolved by making the code more resilient to errors; agent will be restarted when a temporary issue is detected, and the restart will be immune to most exceptions.

AES call to mbean disabled
Resolved in Pega Version 8.4.5
Under certain conditions, the AESRemote 'push memory' agent call to the legacy memory management mbean caused unexpected behavior in declarative rules for work running in data flows and queue processors. This has been resolved at this time by overriding the push memory usage agent activity to skip mbean and connect REST.

Corrected race condition that caused JobScheduler error
Resolved in Pega Version 8.4.5
A race condition between the pzInitializeQueueProcessors and pyPersistNodeState job schedulers that both run at platform's start was causing a null pointer exception with the error "com.pega.platform.executor.jobscheduler.scheduler.JobExecutionException: Activity execution failed with [PRRuntimeException]". This has been resolved by moving the QueueProcessor initialization process from JobScheduler to StartupTask.

Mobile app language remains consistent after data sync
Resolved in Pega Version 8.4.5
When using a Field Service Mobile App where the locale of all workers was set to nl_NL, the UI was intermittently flipping from NL to EN and and back again. This was traced to the locale of the requestor (field worker) being lost during synchronization of the mobile app data to the server, causing the UI to fall back to the default value of EN. This has been resolved by ensuring the requestor always uses the chosen locale for the operator.

Mobile logging updated for data page required parameters
Resolved in Pega Version 8.4.5
After upgrade, the number of warnings increased substantially in the mobile app log file for D_Pages, specifying "Required parameter X for data page X cannot be blank." This was traced to the forced logging related to missing required parameters for Parameterized DataPages during DeltaSyncs. In order to increase the value of the logging, the process has been moved from being called before packaging the Data Page to being printed later in packaging code and set to warn only about any unsupported data page configuration with required parameters.

Hidden Question pages and answers will be saved to DB
Resolved in Pega Version 8.4.5
After a question page was shown and some values were entered, going back to the question and reverting an option caused the question page to not be visible, but the answer values persisted in the clipboard and were eventually saved into the database. This was a missed use case for Question page smart shapes, and has been resolved by updating the pzSetQuestionPageParams data transform so that whenever a question page is evaluated to either to show/hide, when the question page visibility is set to false and the pyClearAnswerValuesWhenQPHidden 'when' rule is overridden, the corresponding values will be wiped from the clipboard and only the required values will be saved to the database. However, please note this is not supported for branching logic and visibility conditions should be used instead.
