Handling added for unavailable oWnd
Resolved in Pega Version 8.5
After using a Snap Start URL to open an assignment, terminating the requestor and hitting the URL again resulted in a blank screen. This was traced to the pzUnknownSessionAlert script throwing an error when oWnd.pega was not available, and has been resolved by adding the needed handling.

Added handling for Google Chrome drag and drop of Outlook email
Resolved in Pega Version 8.5
Attempting to drag and drop an email from Outlook to a case opened in Google Chrome resulted in the email being moved to the Outlook deleted folder. This was traced to Google Chrome defaulting to defining the "dropEffect" attribute as "none" when the expectation is it should be "copy". To resolve this, the recommended handling from Microsoft has been added as an event to make a copy (and not a move) an email from Outlook when dragged and dropped with Google Chrome.

Compilation logic error corrected
Resolved in Pega Version 8.5
A compilation failure on upgraded systems using the JDK 11 compilation of libraries that include Pega 7 functions that have INCLUDE statements that are not supported in JDK 11 was traced to a logic error added when enhancing debug logging. This has been corrected.

DSS added for fall back to legacy decision table format
Resolved in Pega Version 8.5
After upgrade and switch to IL, non-working decision tables created in one class had pyWorkPage mapped to another class. In the column, the properties were mentioned as "pyWorkPage.xxxxx", but at runtime when the non-working decision tables ran as standalone, the system did not ask for values to be entered to evaluate the result. Tracer showed the error as "Goal seek requires missing input property pyWorkPage.All_Offln_Trans_In on page pyWorkPage; details: (unknown)". Investigation showed that the Legacy assembly for the decision table used the lazy evaluation pattern to resolve the expression in the column header in the generated Java code. This resulted in the property for the column header only being read when it was used. However, for IL-based decision tables all properties are read immediately before any rows are evaluated, which requires the property already be present on the page. This missing property from the lazy assembly then resulted in the exception. To resolve this, Executable.generateOrCompileSource and Virtual tableassemblyHandler.useIL() have been modified to fall back to legacy decision table format if the DSS InternalLanguage/disableIlBasedDecisionTable is enabled.

Default compiler pool size increased
Resolved in Pega Version 8.5
An issue was seen where the nodes were continuously terminating and Stream service was not started. Error messages indicated a "WARN - Long running request detected for requestor", and that tasks were waiting for the generic object pool. Analysis showed that it was possible for a deadlock to form during the startup of the system or during the first few rule executions and compilations when there were more than five rules trying to compile. Once the variable LibraryMetadata.TypeEnvironment.resolver (ClassLoader) is initialized, the problem would resolve. To prevent the deadlock, the default compiler pool size has been increased from 5 to 10.

Resolved null pointer on Reference Helper startup
Resolved in Pega Version 8.5
An issue with the system failing to start and generating a NullPointerException on RUFReferenceHelper.java has been resolved by modifying some Rule-Utility-Function code to better handle threads that are not completely initiaized yet but still running rules.

Decision table and tree obey allow missing properties checkbox
Resolved in Pega Version 8.5
Calling the decision table/tree inside another decision table/tree which has a missing property was throwing an error even though the "AllowMissingProperties" checkbox was enabled in the caller activity. Analysis showed that the setting for AllowMissingProperties did not carry into any subsequent DecisionTree/DecisionTable calls from the top DecisionTree/DecisionTable, and this has been resolved by modifying the decision table and decision tree obtain value functions to pass AllowMissingProperties.

API added to minimize calls to set parameters in datapage
Resolved in Pega Version 8.5
Differences were seen after upgrade when using a datapage associated with a property which was application-specific and that had Data Access for the property defined as “Copy data from a data page" with parameters whose value was set by an activity from the associated property of type single page. Prior to upgrade, only one call was seen to set the values for the parameters in datapage, but post-upgrade multiple calls were used to set the values to these parameters. This was traced to logic used for extraction and invoking the perform, and has been resolved by adding the new API 'DeclarativeAction.shouldExtractWatchedProperties'. It will return true or false, depending whether the extraction of watch properties is needed or not.
