Handling added for interaction portal refresh containing many data parameters
Resolved in Pega Version 8.4
Attempting to refresh the browser when there were interactions opened in the Interaction portal and a huge amount of data on the parameter page caused the screen to blank and the interaction content was not displayed. Investigation showed that as part of the refresh, the displayOnPage GET request was sent with all of the parameters in the parameter page (data-model), resulting in a 400 Bad Request due to the browser URL length limitations. This has been resolved by removing the parameters which are not actually required for the displayOnPage GET call during the refresh case.

Escape added to Radio button field value to handle HTML tags
Resolved in Pega Version 8.4
A radio button with a field label to display a help icon and to open the help URL when the icon was clicked did not display as intended. Changing the control to text area produced the desired results. This was traced to the radio button's label being assigned to a field value which returned a string that at some points contained HTML tags, and has been resolved by escaping the pyLabelFor value before assigning it to the aria-label attribute of the radio button's div tag.

Cancel button on embedded GridRow cancels single action
Resolved in Pega Version 8.7
When a modal Flow Action contained a Table with the Row operations configured as Master-detail and the Detail flow action was specified, if a validation error defined in a Validation rule (i.e. other than required field error) occurred while entering details for one of the rows and the Cancel button for that row was clicked, the entire action was cancelled and the modal window was closed without saving anything. This has been resolved by updating the system to prevent the modal closure if a row is added and then cancelled.

Handling added for Pagelist Reference Property in LegacyPageAdapter getMode API
Resolved in Pega Version 8.4
Post upgrade, a "Component Stack Mismatch" error appeared while opening a work item containing an embedded section that used a Data Page D_WorkApprovalCase input parameter as the Page Context. This was traced to an exception thrown by the getMode() API invoked on an auto-populate property because the property was in a read-only data page. By default, read-only data pages are light weight clipboard pages, but auto-populating properties on light weight clipboard pages was not handled via the failsafe page in the getMode() API. This has been fixed by adding handling to the getMode API of LegacyPageAdapter for properties not supported by redux ( eg: reference, autopopulate properties etc).

Checks added for empty/missing properties during rule restoration
Resolved in Pega Version 8.4
After making a change to the harness and checking it in, restoring an old version of the harness from history resulted in the old version of the rule displaying a missing or corrupted button area. The was caused by the rules revision history not keeping empty / default properties in the DB, so when the rule is restored those properties were not populated in the resulting XML. To resolve this, empty checks and default values have been added for any non-existent properties in pzpega_ud_gridlayout_model JS and pzpega_ud_gridlayout_structure JS.

Links to specifications persist appropriately
Resolved in Pega Version 8.7
When linking Rules to Specifications, check-ins of some unrelated rules deleted the link. Investigation showed the deletion happened in the pzHandleLinksPostCheckIn activity, and was caused by an empty parameter page name that caused pcInsKey to not have a value, so all links returned by "Obj-Browse" were later deleted. To resolve this, an update has been made to insure the "Pass current parameter page" option in step 2 of the Connect REST PostCheckIn activity is enabled so that the downstream activity pzHandleLinksPostCheckIn behaves as expected.

Performance improvements for stale thread warnings
Resolved in Pega Version 8.7
Stale thread warnings were causing performance issues during dataflow run execution. Stale thread/slow component warnings are added as part of the dataflow execution when a processing thread takes more than 5 minutes to process a single dataflow record. The stacktrace of the dataflow thread is added as part of the warning for debugging purposes, but in some scenarios the stacktrace can become very large. This has been resolved by removing the stacktraces from the warning, improving the query logic, and adding the run ID to the exception method to assist if there is an error.

Fallover stategy added to chat routing to keep event processor running
Resolved in Pega Version 8.4
Chats were becoming stuck in the queue and end users were not able to connect with the customer service representative. An excessive number of queued items were observed in a Queue Processor named "EventProcessor". This was traced to the setting "Browse from the offset" having been removed because of a retention policy. This resulted in "Browse from the end of the stream" being used instead even though browse should start from the earliest known offset. To resolve this, Stream Producer will be cached based on topic, and Stream consumer will fall over to an earliest strategy in case the requested offset isn't found so the event queue will be handled in a timely manner.
