pzTenantID removed from Revision management classes
Resolved in Pega Version 8.5.4
After upgrade, issues were seen with case types in the case explorer. This was caused by the Revision management work classes created in the 7.1.x version having pzTenantId property in the rule XML when it was not defined anywhere in the 8.x versions, and has been resolved by removing the pzTenantId property from the Revision management classes.

Queue Processors made more robust
Resolved in Pega Version 8.5.4
After upgrade, multiple queue processors were not running as expected. Attempting to restart them generated an error. Investigation showed that the real time data flow runs were not picking up or accepting assignments because the local node was under the impression it was still processing data. In this case, the need to synchronize the state of multiple threads caused the queue processors to become stuck in an initializing state due to a race condition that caused the data flow engine to think this run still had threads running when all threads were already stopped. To resolve this, the callback handling has been simplified and made more robust. In addition, in some cases the data flow leader node would believe the service nodes did not accept assignments even when they did. This occurred if many runs and nodes were involved, and was traced to an implicit limit on the NativeSQL query used to read the data to see which assignments were accepted. To resolve this, the key-value store in the Service Registry has been modified to allow a query of more than 500 entries at once.

Special characters escaped for use in "is in List" lookups
Resolved in Pega Version 8.5.4
After creating a specific criterion on any proposition using a string property, the "Is In List" operator, and a customer list with one value containing a "$", clicking save or check in resulted in the exception error "Problem invoking function: pega_decisionengine_propositionfilterfua.pzPropositionFilterMethodBody--(PublicAPI,ClipboardPage) java.lang.IllegalArgumentException: Illegal group reference at java.util.regex.Matcher.appendReplacement(Matcher.java:857) ". This has been resolved by escaping regular expression control characters in string replacement, which will allow the use of characters such as the $ sign for "is in List" lookups.

Decision Table check-in warnings supported for large tables
Resolved in Pega Version 8.5.4
After adding an empty row in the middle of Decision Table rows and checking in, the Decision table rule's CheckIn form shows a functionality warning about a conflict in decision table ("This rule contains 1 logic conflict(s). Click the 'Show Conflicts' button for more details."). However, this behavior did not occur as expected if the decision table had more than 500 cells in it, and has now been resolved.

Expression Builder updated for special character handling
Resolved in Pega Version 8.5.4
If a modulo operator (%) was used in expression builder, the expression showed the correct value when it was submitted (closed) but on reopen the expression was changed and not calculated correctly. If the expression was not reopened then it calculated the value properly. This issue was traced to a server call to pzEvaluatePegaExpression which treated certain values as containing special characters, and has been resolved by updating the handling for this scenario.

Decision table null input handling updated for backward compatibility
Resolved in Pega Version 8.5.4
After upgrade, any null values as inputs in the decision tables were skipped if "Allow Missing properties" was not checked. This behavior was different from previous versions. In order to improve backward compatibility, the new function pxEvaluateDecisionTable has been added which has an additional parameter to set AllowMissingProperties, and the older function logic has been modified to take the parameter value from the parameter page.

Support added for connect-SOAP run in parallel mode
Resolved in Pega Version 8.5.4
When connect-SOAP was configured to use the “run in parallel” mode, application settings derived through a datapage had incorrect values. While running the connect-SOAP through an activity, all the values were derived incorrectly. This has been resolved by adding a synchronization enhancement to support parallel run connect.SOAP.

Logic updated to handle decision trees over 64k
Resolved in Pega Version 8.5.4
Logic updated to handle decision trees over 64kAn exception was thrown when decision trees reached the 64K size limit. This has been resolved by modifying the logic in the DecisiontableMethodBody Rule-Utility-Function where the split size nPropRowLimit is based on the number of columns.

Mobile logging updated for data page required parameters
Resolved in Pega Version 8.5.4
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.
