ADM initialization modified to eliminate unnecessary keyspace creation triggers
Resolved in Pega Version 8.2.2
On startup, ADM issues a Cassandra query to create one of its keyspaces if it doesn't already exist. To do this, it was set to require creation level permissions whether it created the keyspace or not, but those permissions may be considered a potential security violation if the Cassandra instance is shared with other teams. If permissions were restricted to only below key spaces used by Pega, then the ADM node would not start up. To resolve this, the way ADM initializes its keyspaces and tables has been modified so that queries requiring 'create keyspace' permissions are not triggered if the keyspace already exists. These changes also include code that ensures that keyspace and table creation can only happen on one node in the cluster at a time.

Rounding added to avoid exception for ADM number too small to save to Oracle
Resolved in Pega Version 8.2.2
An exception was thrown when trying to save ADMSnapshot agent predictor bin data that was too small (below 1 x 10-130) for the Oracle Number column it was written into. This blocked up-to-date reporting on adaptive models. To resolve this issue, the code has been modified to round the double type numbers to an acceptable scale before writing to the database.

Controls updated to handle hidden values in finishassignment submission
Resolved in Pega Version 8.2.2
A SECU0001 alert was thrown from the out-of-the-box function finishassignment upon the submit of assignments. This was traced to an alert generated while attempting to post the feed even though there was no Pulse gadget used in the work object, and was due to the handling of hidden fields as read-only. Since the read-only values were not editable, they should not be submitted with the request body; this has been corrected by modifying the hidden control entry handle such that hidden property is considered as editable-filled. Controls have also been added to pxHidden to prevent potential misuse.

Added check for blank Value List Property referenced in Dropdown Control
Resolved in Pega Version 8.2.2
When a value list property was referred in the Dropdown control, the dropdown was shown as empty. This was traced to a property of type value list / value group, ClipboardProperty.getName() api returning as empty. To resolve this, a check has been added to ensure the value is populated with the correct property name if it is blank.

Added check for visible SmartInfo so focus is maintained
Resolved in Pega Version 8.2.2
After setting up a harness that displayed page-level messages at the top and bottom with "info" icons in a grid that displayed SmartInfo, hovering on one of the "info" icons when a page-level message was displayed caused the page to scroll up to the page-level message at the top of the harness instead of displaying the SmartInfo popup. This has been resolved with the addition of a check for visible SmartInfo in pzpega_ui_doc_errors.js so the focus is properly set.

Added check to maintain key value when using collapseAllMenu in child navigation menu
Resolved in Pega Version 8.2.2
After a navigation menu had a child added as reference navigation menu that used the function collapseAllMenus, the screen was freezing if a link was clicked in the added child navigation and a javascript error appeared on the console screen. This was traced to an improper key being set in sessionStorage object in setItem due to the nesting, and has been corrected by adding a check in sessionstorage setitem to maintain the proper key value.

Added handling for better recovery and reset when using 'When' conditional row deletion
Resolved in Pega Version 8.2.2
Given a 'When' condition configured so that a specific row could be deleted, trying to delete another row resulted in the expected error indicating it was not possible to delete that particular row. However, attempting to then delete the row with the 'When' condition caused the same failure error to appear which could not be cleared through clicking on the Refresh button for the section. In order to resolve this, handling has been added for a scenario where Obj-Delete fails and the record is marked for deferred commit. In this situation, the system will revert Obj-Delete by way of Obj-Save-Cancel in @baseclass.pzDeleteRecord so that a subsequent Obj-Delete does not pick up the previous record and fail again.

Added handling for cases where Microsoft Internet Explorer causes a SAXParseException
Resolved in Pega Version 8.2.2
Numerous SAXParseException messages were seen in the log file, and the queryString showed the pyDeleteDocumentPg being referenced. This was traced to the method used by Internet Explorer to construct an HTTP request: Microsoft Internet Explorer sends the header and body of the request in separate TCP packets, but for an unknown reason in this case the body packet goes missing. To resolve this, a toggle has been introduced which will send the pyDeleteDocumentPg request as GET if pega.u.d.GET_REQUEST_DELETEDOCUMENT is set to true in userworkform. In a normal flow without this variable, the request will pass through the normal flow.

ADM pulse timing changed to inprove performance on very large clusters
Resolved in Pega Version 8.2.2
ADM uses a pulse that checks if any models need to be updated. This uses a Cassandra query which has no "where" clause, causing poor performance for very large clusters. For immediate relief of this issue, the pulse configuration has been updated to increase the timing from 30 to 300 seconds so it fires less often. Model updates typically happen every x hours and often the pulse will not detect any models that would need to be updated. Further improvements in this process will be available in a future release.
