Save Button for Delegated rules is displayed correctly
Resolved in Pega Version 8.3.1
The save button for delegated rules was displayed in a truncated shape. This has been corrected by removing the split-left style from all of the buttons that are intended to be standalone and not have a drop-down actions menu.

Added workaround to handle HiddenPropertiesToIgnore when a page is in Read Only mode
Resolved in Pega Version 8.3.1
A 'WrongModeException' was generated while trying to use the Data Transform pxHiddenPropertiesToIgnore to remove system properties from page. When the Datapage was set to Editable/Savable mode, the Activity ran without an error and executed the Data transform. When the Datapage was in Read only mode, the error occurred. This was traced to a process that previously was allowed to set a page to an empty string, but which was removed during recent work. To resolve this, four instances of pxHiddenPropertiesToIgnore that included Single Page Value properties have been updated by moving them to the bottom of the Data Page and changing them to an "Update Page" from a "Set".

Clipboard ExecuteActivity button updated to get classname
Resolved in Pega Version 8.3.1
In Clipboard, clicking the execute activity button did not trigger any action in the backend. Investigation showed that previously the ID attribute for the HTML element used to be same as the property name, and the value of property "pyClassName" was found in the document.getElementById function. Due to work done to provide a feature that generates unique IDs for UI elements (auto generated controls), this must be done through other functions such as document.querySelector to get the value of the property from DOM. The necessary updates have now been made to the javascript function in control pzExecuteActivityButton.

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.

Case status correctly updated when using RDA
Resolved in Pega Version 8.3.1
When a Assignment was routed to a work queue, and Flow Action post processing was set to trigger an RDA Automation to update some case property, an error appeared saying there was no data available on the Page and the case status was not updated when it moved to the next stage. This was an issue with case status not being correctly updated when using robotic automation, and has been resolved.

Modifications to getFunctionalServiceNodes process
Resolved in Pega Version 8.2.7
The count of the Interaction History write related threads was increasing rapidly and a stack trace indicated "waiting on condition" and "java.lang.Thread.State: WAITING (parking)" errors. Investigation showed that this was due to getFunctionalServiceNodes using Hazelcast to determine node status by making a service request on an installation with a very large number of nodes, causing thread locking. To resolve this, the implementation has been updated to avoid calling getFunctionalServiceNodes on save of Interaction History, instead using Cassandra and only calling getFunctionalServiceNodes on the master node, not on all nodes.

Behavior made consistent between SSA and legacy engines
Resolved in Pega Version 8.2.7
There was a behavioral disparity between the legacy execution engine and the SSA engine where the latter was not creating a new page when the index was one above the size of the page list. This has now been corrected in order to make the SSA behavior fully backward compatible with the legacy engine, i.e. a new blank page will be added to the list if the index is one above the size of the list.

Updated precondition checks for Tumbling Time data in event strategies
Resolved in Pega Version 8.2.7
Tumbling Time data keys in event strategies were not being properly executed when certain window configurations were used. This was has been resolved by turning off the optimalization of Cassandra reads for small windows when window size is not known upfront and set dynamically (set size by property). In addition, an issue with Cassandra timeouts after the dataflow run had been running for several months has been resolved by adding a 'time to live' value for tumbling time windows, and event strategies has been switched to use leveled compaction by default.

Improved management for table pr_log_dataflow_events
Resolved in Pega Version 8.2.7
The Lifecycle event table was sometimes growing too large. This additional strain of database transaction volume caused poor performance on the Dataflow tier and lead to cluster instability and time-consuming cluster restarts. Due to problems in one of the Pulse tasks, the Pulse thread was not processing single case metrics properly and causing the unbounded queue for single case to grow. This has been addressed by switching to a fixed queue size, which is configurable with the DSS: dnode/single_case_queue_size. The default value of the DSS is 4000, and if changed a system restart is required. An error will be logged each 1000 queue misses, and metrics will be dropped if the queue is full. In addition, the Pulse task frequency has been improved and managed to prevent interference with other Pulse tasks and will be triggered only if a run is system-paused for a long interval. Rebalances now have a failsafe if something unexpected happens during the Pausing of the run, and If the cluster becomes unstable, the life cycle events logs may be disabled with dataflow/run/events/persist .

Updated COUNT logic for strategies with ssavm set to true
Resolved in Pega Version 8.2.7
An error was seen when attempting to save a strategy after setting ssavm to true, indicating an issue in the “COUNT” method in Group By shape. Since the source field is not used and does not need to be evaluated here, the system has been updated to ignore the source field if the operation is COUNT.
