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.

Updated AgentName handling for QueueItemID
Resolved in Pega Version 8.7.1
A report was showing as scheduled but no mail was received when it was supposed to run. Investigation showed this was due to the reports being corrupted, leading to the flow skipping the necessary Queue-For-Agent method. While there was a workaround of doing a "Save As" to create a new version of the report, this has been addressed by setting the agentName before saving to the database to handle missing agentName cases and ensure pyAgentname is always populated when pzQueueItemID is not empty.

Added check for attachment upload for filename ending in $
Resolved in Pega Version 8.7.1
Attempting to upload a file to external web storage was failing if the filename's last character was $. This was traced to the system attempting to decode the name, and has been resolved by adding a check to see if there are at least two characters after $. If there are none, the decode step will be skipped.

Check added for empty SendAs in MSGraph
Resolved in Pega Version 8.7.1
When using MSGraph, logging showed the errors "Could not parse the address into InternetAddress Objects, falling back to parse with the regex" and "Unable to use the configured "Send As" email address from Records. Will fall back to 'first' recipient of incoming email." This has been resolved by adding a check for a blank SendAs field.
