Tracer issues resolved for Google Chrome browser
Resolved in Pega Version 8.3.1
Tracer was running in the background even after the tracer window was closed. Attempting to run a Tracer in this condition resulted in an error indicating the Tracer was being run by another operator and should be restarted, and in the Dev environment, attempting to start a Tracer once it was closed resulted in the message "Cannot launch multiple Tracer sessions for a requestor." Investigation found that the Tracer session was not being closed when the tracer window was closed because the browser specific method intended to do so was not being called. This was found to be an issue caused by the Google Chrome browser changing the signature of the method, and has been resolved by updating the method name in the TraceMain HTML rule.

Support added for referencing Page Group property inside of strategy
Resolved in Pega Version 8.3.1
Referencing a page property under Page Group property inside a strategy resulted in a runtime error of ClassCasting: "java.lang.ClassCastException: java.util.ArrayList cannot be cast to com.pega.decision.strategy.ssa.runtime.ClipboardPage". The issue was traced to the SSA optimized code for the GetPage SSA assuming that the GetPage SSA would only have another page as a parent. In order to handle the above scenario where GetPage would have a GetPageCollection as a parent and return a List of ClipboardPages, a GetPage function has been applied over each entry in the results of the GetPageCollection SSA using a MapAction SSA. Some optimizations will be applied in cases where the GetPageCollection has only one entry, which will replace the MapAction with a simple GetPage action.

Added differentiated handling for special symbols based on location in the label string
Resolved in Pega Version 8.3.1
While importing an Excel file into a decision table that used custom functions like@string:notequal or equal, label names like 'AlphaPrefix !=AAA' resulted in the error "invalid expression or reference: line 1:28 extraneous input '"True"' expecting {<EOF>, '-', '+', '=', '*', '/'," " . Investigation found that the problem was with the label of the column not handling the the special characters like (‘!=’, ‘<’ , ‘<=’, ‘>’, ‘>=’ ) present in the middle of the label string: the label and default operator were being updated irrespective of the location of the symbols within the string. To resolve this, DecisionTableWorkBookConverter.java has been modified to set the operator only if the special strings (‘!=’, ‘<’ , ‘<=’, ‘>’, ‘>=’ ) are present at the end of the label.

Export to Excel total result count disabled
Resolved in Pega Version 8.3.1
After upgrade, an imported report with more than 30k records took an excessive amount of time (6-7 minutes) to be exported to Excel after being run, and the resulting Excel file only contained one record. A child report having around same number of records was exported successfully in around 30 seconds. Analysis showed that during the export process, a thread dump was originating from the thread responsible for performing export. Co-relating this with alert logs showed a PEGA0042 alert around the packaging of the query. This was traced to the paging settings on the pyContentPage not getting properly set from the activity pxRetrieveReportData on step 14: the boolean that sets .pyContent.pyPaging.pyReturnTotalResultCount used a page that will always be empty on the upgraded system, leading to an error in calculating the total result count. To resolve this, fetching the total result count on Export to Excel has been disabled.

Multi-nodes rebuild LibraryMetadata to ensure all Rule-Utility-Functions are present on change
Resolved in Pega Version 8.3.1
When performing a complete Application import into a clean installation, references to certain Rule-Utility-Functions went unresolved during the initial assembly. Investigation showed that after introducing a new Rule-Utility-Library or Rule-Utility-Function on one node in a cluster and then generating that, the other nodes in the cluster did not have the correct LibraryMetaDataCache for that Rule-Utility-Library. Therefore assemblies on those other nodes could be bad and throw a runtime UnresolvedAssemblyError. This has been resolved by modifying the way the Library subsystem processes the node changes events for Library Generation to ensure that each node completely rebuilds the LibraryMetadata for that Rule-Utility-Library so it contains all the Rule-Utility-Functions.

Validation error messages persist appropriately
Resolved in Pega Version 8.5.2
Whenever there was a Validation check on a flow action Validation Tab and Post Processing Activity, the error message appeared on the screen momentarily and disappeared. Intermittently, the validation error would stay on the screen after appearing a second time. This was traced to the refresh action happening in the wrong context due to the refresh action of the Ajax container being called twice, once in postacrenderac and another time in the harness unload function.The case error DOM was present in the markup, but because of the refresh in the harness unload, the error message was removed from the DOM. This has been resolved by changing the refresh call from onHarnessUnload callback to postAcRender callback. Logic has also been added to prevent refresh when error messages are present.

Removed services check and added warnings for simulations
Resolved in Pega Version 8.7.1
Attempting to run an audience simulation resulted in the error "Running simulations is not possible, because the required services are not available. Contact your system administrator to enable the data flow and real-time data grid services". Investigation showed the @DsmServices.pxHasFunctionalNodes("DataFlow","Batch") function call contained in the 'when' rule pyUnavailableDecisionServices was returning false even if all the nodes were in the cluster and all the DSM Services were in NORMAL status. To resolve this, the services check has been disabled and the simulation run will show a warning or fail if a data flow run is queued for more than 30 secs or if there is an issue with querying the underlying metrics storage.
