PropertySet will iterate over changeList map copy to resolve CME
Resolved in Pega Version 8.4.1
An empty menu was seen intermittently when handling incoming email, and a ConcurrentModificationException error was logged. Investigation showed that a step scope changeList map used in the handleChaining method was sometimes modified by another process while the first one was iterating over it. To resolve this, PropertySet will receive copies of the change list map from clipboard pages instead of the original map.

Decision table and tree obey allow missing properties checkbox
Resolved in Pega Version 8.4.1
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.

Null check added to resolve addmapcasetomap error
Resolved in Pega Version 8.4.1
Using a createcase flow shape to create child cases by looping on a page list on the parent case resulted in pzaddmapcasetomap throwing an exception related to the activity pzLoadCaseHierarchyWrapper in step 5. This was traced to a page being removed after the list of pages was received in findPageByHandle, and has been resolved by adding a null check.
