Load more works in non-templatized layout
Resolved in Pega Version 8.8
After adding a repeating dynamic layout inside a tab group layout (which is a deprecated feature) to make it non-templatized, the progressive pagination option to show the "load more" button did not work. This was caused by the load more functionality having a dependency on pega.ui.RDL even though pega.ui.RDL was not available in case of a non-templatized grid, with the result of generating an exception which broke the flow. This has been resolved by adding a null check which will allow the flow to proceed whether the grid is used inside non-auto-generated or auto-generated elements. Please note that it is strongly recommend to update any deprecated layouts to Layout Group as it is a best practice to keep the code updated to avoid any compatibility issues.

Added parameter skipPropertyEvaluation to handle CSS in email HTML
Resolved in Pega Version 8.4.4
While sending an email with custom HTML appended to the email body, a "+" sign in the body was causing the correspondence generation to fail. Investigation showed that if there were CSS classes with braces in the message body, the braces were being removed and replaced via "+" symbol in step 21 of CorrCreate activity. To resolve this, a new Boolean parameter skipPropertyEvaluation has been added in the CorrCreate activity to handle the decision to either evaluate the logic or not, and the pre-requisite will be to resolve all the property references before calling this activity so custom CSS braces { } will be honored when the message body is sent.

Updated Tracer for cluster events
Resolved in Pega Version 8.4.4
When running the tracer from the Admin Studio Listener management landing page, Tracer was always fetching data from one node only even though events were generated on another node. This was due to the specific node where the Listener was running being passed to the concern activity while launching the tracer; the Tracer Client node did not have data to check if the event was being populated on another node, and the result was to always fetch data from one node only even though events were generated on another node. To resolve this, the web node ID where the event is running will be passed.

Application wizard security updated
Resolved in Pega Version 8.4.4
A user having PegaRULES:User1 role only was able to run the Create Application wizard until an authorization block was reached, yet some rules were created. No operator records were created as part of this process. This was traced to code left in place after the creation of pxAppConfig and pzAppConfig portals, and has been resolved. The New Application wizard UI will display a message to a user when they lack access to build a new application, and an error will be displayed for any attempt to create a new application directly via pzCreateNewApplication to address a scenario where a user might be trying to call the activity without the front end.

Added debug logging and exception recovery for unexpected data object
Resolved in Pega Version 8.8
When rules were complied in lower environment and deployed into production, they later became corrupted and system behavior changed. The error "Java generation failed: caught exception while expanding property pyGetCasePredictionsByClassName on page CurrentRecord" was generated. Investigation showed the auto-populate property pyGetCasePredictionsByClassName was attempting to get the metadata property "pzDataObjectParams": this was a string value in this scenario instead of the expected java object, and caused the exception. To resolve this, a debugger has been added which will check if the property is a java object or not. If it is not, the system will skip the processing and then display an error message with a stack trace.

Explicit lock release added for Cassandra threads
Resolved in Pega Version 8.8
Customer Decision Hub was not responding for realtime request REST service calls, and thread dumps during start up were showing all HTTP request threads were stuck in CassandraSessionCache.getSession. If an error is thrown while invalidating an old Cassandra session, the system may fail to unlock the write lock. This results in subsequent threads being blocked on the session cache's ReadWriteLock when they attempt to retrieve the session from the session cache. To resolve this, an update has been made to ensure that invalidate session is wrapped in a finally block that releases the write lock and log any thrown errors.

Corrected report definition save-as-image option
Resolved in Pega Version 8.8
Attempting to save a report definition as an image resulted in an access denied error stating "Browser fingerprint validation failed : A request was received with an invalid or missing browser fingerprint. The request was denied", and the user session was closed. The security SECU0017 alert is generated when a request is sent to a Pega application and the browser fingerprint is either missing or does not match the expected value. The system tries to check the type of request for every requestor ID and fetch the CSRF token, but in this case it was not matching with the token present on the requestor thread. This has been resolved by adding scripts to send the hidden input value needed.

Handling added for multi-file upload of duplicated files
Resolved in Pega Version 8.7
Attaching the same file multiple times during a single upload caused some of the duplicated files to not be included. The issue was not seen when attaching the same file multiple times but in different attempts. The exception "Can't continue with file attachment. FileData.xlsx is missing and might have been quarantined by anti-malware software" was logged. This was caused by the files being uploaded without updating filenames to have a unique ID, so multiple files with the same name were overwriting the previous file. This has been resolved by setting the appendUniqueIdToFileName parameter to true in the upload request so each copy of the filename is treated as an individual file.

JAWS announces popup error message
Resolved in Pega Version 8.4.4
When a form is submitted without giving value to required field, a browser pop up appears. The expected behavior is that the screen reader (JAWS) should move the focus to the field that has error and read the error message However, JAWS was not announcing the error "Value cannot be blank". This was traced to a scenario where if pega.u.d.fieldErrorType === "ERRORTEXT" is true, the class on the span within the error div will be set to "inputSpans", and this resulted in the return of an empty array for document.querySelectorAll("span.iconError.dynamic-icon-error"). To resolve this, support has been added for the "inputSpans" class.
