Handling added to maintain custom modal template name after errors
Resolved in Pega Version 8.1.4
When using a grid where each grid row had an Edit button which launched a modal dialog with a custom modal template, the post action activity of the flow action introduced error messages on a top level page (not on primary or pyWorkPage). Clicking the submit button again caused the modal dialog size to shrink and not work after that. This was traced to the second submit using the system's pyGridModalTemplate instead of the custom modal template due to the modal submit button being replaced with new markup. To resolve this, the modal launch will now use the "pega.u.d.submitModalDlgParam.modalSection" variable which will have the modal template name. In addition, a check has been added to ensure this is not passed as null.

Connection Manager uses keyring for null prconfig password
Resolved in Pega Version 8.1.4
After upgrade, credentials from BIX keyring were failing when using BIX via commandline rather than prconfig. This was traced to a behavior change in the Connection Manager, and has been resolved by modifying the Connection Manager to look up the password from the keyring when given a URL configuration where the password is null in prconfig (URL connection only).

Improvements made for the stability and reliability of the stream tier
Resolved in Pega Version 8.1.4
Several enhancements and fixes have been made to improve the stability and reliability of the stream tier with a focus on rolling restart. Issue 410567: When a stream node shuts down, it takes up to a minute for all client nodes to recognize the event and failover to other nodes due to large default timeouts. Timeouts have now been reduced to allow nodes to failover much earlier. Issue 413375: When a stream node shuts down, other stream nodes are notified and attempt to discover the new cluster topology. Since the cluster is still in flux, this operation may take a long time blocking all producers until a new topology is determined. This procedure has been changed to be less heavy and make the discovery only if required. Issue 401326: Kafka (running as a separate process as part of the Stream services) generates log files, but does not use log rotation with a maximum amount of log files. This means that the log files will eventually fill up the disk, leading to failures of the service and PRPC instance running on the same disk. To resolve this, the system will now limit number of generated log files to prevent high disk usage by using the parameters of file size = 2 MB and a max nr of size = 10. Issue 410280: A large number of ""Processing override for entityPath"" entries were seen in the Kafka logs. This has been addressed by ensuring message.timestamp.difference.max.ms is set to equal to retention.ms. In addition, the system will properly compare the Kafka Configuration created for the entire topic and the configuration retrieved for Partitions so the configuration is not unnecessarily updated. Issue 414765: During stream node restart, decision hub nodes may block for 15-30 seconds when writing to a stream data under certain conditions. This can cause high response times for a small period. This has been addressed by updating stream dataset logic to handle stream tier restarts properly and not cause response time degradation. Issue 401093: HttpMessageDecoder was throwing an exception regarding “TooLongFrameException” causing a 502 on HTTP stream tier requests going over 8192. The default max header size used by stream data set REST service was 8KB. In this particular case, the HTTP header contains a lot of cookies and other meta-info and exceeds 8KB. To resolve this, the default max header size has been increased to 16KB. A new prconfig setting to control max header size has also been introduced.

Check added for custom section use in Summary report exported to Excel
Resolved in Pega Version 8.1.4
Criteria were missing when Export to PDF was used for Summary reports filtered by a custom section. This was caused by the needed pyQueryTokenList not being repopulated for the export in the case of custom section use, and has been resolved by adding a summary report check in the pzIncludeCustomFilterSection section before invoking pzClearRDTempFilters function.

New Activity added to ease cleaning up Thread-level data pages
Resolved in Pega Version 8.1.4
It is an expected behavior that the system will not automatically remove read-only data pages, as the decision of which pages need to be removed is system-specific. However, it was noted that an accumulation of Thread-level Data Pages may eventually cause performance degradation. In order to make it easier to clean these up, the new extension Activity "pyRemoveThreadLevelPages" has been introduced that is called from the DoUIAction activity.

Dropdown sourced from data pages or clipboard pages working for all browsers
Resolved in Pega Version 8.1.4
After working to resolve a dropdown issue with Edge browsers, some other dropdowns sourced from a data page or clipboard page were failing to load. This was caused by the dpparams parameter being encoded so that the proper JSON was not retrieved, and has been fixed by modifying the system to decode it before passing the postdata.

BIX extract connection leak repaired
Resolved in Pega Version 8.1.4
The first time that a BIX extract was run it failed with a timeout. Running it again immediately was successful. Investigation showed that if the BIX connection timed out, the connection was not being returned to the connection manager due to a failure to reset the autocommit for a connection that partially ran but was not properly closed. This has been resolved by adding handling that will return the connection to the pool and clear the map if there is an exception. Further refinements will be made for timeout issues in multi-tenant environments in a future release.

New MaxFileSize extension point added for pyMaxFileSizeViolation
Resolved in Pega Version 8.1.4
A severe guardrail warning was raised when saving the activity pyMaxFileSizeViolation into a ruleset. This was traced to the CheckForWarnings Activity of Rule-Obj-Activity which checks if any activity referenced is an internal activity. Activity pyMaxFileSizeViolation was calling the internal pzGetCMMaxFileSize activity, and the warning appeared because the py activity was overridden in the application ruleset. To resolve this and add an extension point, pzGetCMMaxFileSize has been modified to a new data transform called pxGetCMMaxFileSize, which is called in pyMaxFileSizeViolation.
