Kerberos handling updated for database remap
Resolved in Pega Version 8.4.5
After upgrade from Pega v7.2 to Pega v8.4, using Kerberos authentication was failing during the remap task. Investigation showed that null username and password values were being passed to SchemaAssignmentUtility along with the flags as arguments, causing the utility to misinterpret the arguments. As arguments should be populated only when flags and values are available and not null, an update has been made which will set the username and password flags only if they are not null in the Remap database tables target.

Web Tier busy threads released on timeout
Resolved in Pega Version 8.4.5
Tomcat Web Tier Busy Threads were not being correctly released, causing stability and performance problems that included health check pings not receiving a thread to service the request so the node was marked as bad, users were quiesced, and the node replaced. Investigation showed the 'put' on the blocking queue did not time out when the queue was full and waited indefinitely, keeping the thread blocked. To resolve this, the system will use 'offer' on the blocking queue instead of 'put' to force thread release on timeout. In addition, debug logs have been added to understand when the offer (or Put) does not succeed and the state of the queue that is causing this issue; the debug logs for class com.pega.pegarules.session.internal.serverpush.RoboticAutomationImpl should be enabled only if the thread busy issue is observed and for limited time window while actively debugging.

Query added to find time zone for MSSQL database
Resolved in Pega Version 8.4.5
The exception "com.microsoft.sqlserver.jdbc.SQLServerException: xp_regread() returned error 5, 'Access is denied.'" was generated when the AES agent PushDBSizeInfo was being run. This was traced to the GetDBInfo activity trying to retrieve the time zone of the MSSQL database by executing a query that used a Microsoft SQL routine to read the windows registry to get the current time zone. The error was not due to security within the SQL Server, but instead was caused by Microsoft Windows security related to the permissions on the registry keys for the users under which specific SQL Server processes were running. To resolve this, an update has been made to call a different query which will get the time zone for the SQL Server.

Resolved Push Node Daily Information exception
Resolved in Pega Version 8.4.5
The "Push Nodes Info Daily" agent was generating an exception on each of the nodes. This has been resolved by enhancing the PegaAESRemote code to handle the exception and get the node info locally, then push it to the console when it is not able to get it via the cluster management API.

Performance improvements for Ajax tab switching
Resolved in Pega Version 8.4.5
When using a 360-view of members in a portal implemented with an Ajax container that showed information in multiple tabs, tab switching was taking a lot of time even though the data was already in the memory. Updates have been made to improve performance.

Updated specificity for custom-format inputs
Resolved in Pega Version 8.4.5
After upgrade, custom formatting for a link control was not working in the skin or during runtime. This was an issue where identical format names used for links and text components caused selectors from the text area to take precedence over link styles, and has been resolved by updating styles to increase specificity for inputs instead of links.

Section Include error handling updated
Resolved in Pega Version 8.4.5
When trying to add or include a section in the design template mode of a section rule or during run time of the application, the error "java.lang.StringIndexOutOfBoundsException: String index out of range: -1" was generated. Investigation showed this was originating from the SectionIncludeForm_Post activity of the class Rule-File-Form, and was traced to a system error related to the 'if' condition which verifies the circular reference of the section being newly added. Because this was a system error and not one generated by Pega, there was no handling for it. To resolve this, the sectionincludepost activity in rule-form class has been updated to determine the source and properly handle the error messages.

Added handling for switching table context in a section
Resolved in Pega Version 8.4.5
After configuring multiple tables in a section with row-editing on master-detail, opening the detail section of one of the tables and clicking inside it and then trying to open the details of another table generated the error "Can not render section'. The section would render correctly if the browser was refreshed. Investigation showed this was due to the new section opening in the wrong context, and the system has been updated to support this use case.

Header present in timeout modal window
Resolved in Pega Version 8.4.5
After upgrade, the header was missing in the session timeout modal dialog when using the pzDisplayModalDialog FlowAction with the pzDisplayModalDialog HTML Rule. This was traced to the title value fetched from HTML not being set for use in the onload function of iframe, and has been resolved by ensuring it is handled by the pzDisplayModalDialog HTML rule.

Check added to match time zone for Time Picker
Resolved in Pega Version 8.4.5
Time picker popup was showing minus 5 hours from the actual value in the time input field, though the value was updated correctly in the clipboard. The console error "Unchecked runtime.lastError: Could not establish connection. Receiving end does not exist." was seen. This only happened when using the non-template mode of the Datetime control and configuring it with TimeOfDay property with the combination of Allow text entry as "No" and onchange event as Refresh-Section. The issue was not seen if Allow text entry was "Yes" from the presentation tab or if the event action "Refresh-section" was removed. This was caused by the markup process using the operator time zone to format the value but the default time zone (GMT) for the data-value. This has been resolved by adding a check in non-template mode so the value markup will be generated using defaultTimeZone.
