Resolved errors when using Build Model from the Preview Console
Resolved in Pega Version 8.3.2
Using the Web Chatbot interface and trying to perform Build Model action from Preview Console failed with multiple errors, either "This action is not allowed as it is outside the current transaction" or "class <blank> doesn't exist". This was traced to issues with the transaction during model update, and has been resolved by conditionally disabling the show page step of pzGetModelProcessStatus. This step creates a difference in the context of the current transaction and is disabled when called from Update API.

UpgradeOnOpen updated to use property set
Resolved in Pega Version 8.3.2
After upgrade, using the revalidate & save wizard on MapValue rules (Rule-Obj-MapValue) generated null pointer exceptions in the tracer file and rules failed with bad status. This was traced to changes made in the Java step of UpgradeOnOpen that used the getReference() method, and has been resolved by updating the UpgradeOnOpen activity in the Rule-obj-Mapvalue class to use property set.

HandleResponses updated for use with optimized campaign
Resolved in Pega Version 8.7
After updating from Pega 8.4, responses were not processed in the pxHandleResponses Data flow if the "pyCampaignOptimization" flag was set to true. This was traced to a missed use case for an optimized campaign, and has been resolved by modifying the condition in HandleResponses.

ExecuteRDB call updated to use NativeSQL for blob
Resolved in Pega Version 8.3.2
After creating a test activity to clear data set records that used the DataSet-Execute method and passed the data set name and truncate operation, only 51 records were deleted in a single run when the data set had more than 51 records. Investigation showed that for blob tables, the database truncate operation was using executeRDB with an empty results page, i.e. it didn't specify pyMaxRecords, which on some databases might have limited the number affected records. To resolve this, the executeRDB call in the database truncate operation has been modified to use NativeSQL for blob tables.

Value Finder updated for use with external Cassandra nodes
Resolved in Pega Version 8.7
Attempting to use the Value Finder feature resulted in the error "Running Simulation is not possible because the required services are not available. Contact your System Administrator to enable the data flow and decisioning data store services." Analysis traced this to a check which identifies whether there is more than one internal node available for CDH/ DSS node. Since there were only external nodes available in this scenario and no internal nodes, the method returned false and returned the error when the CDH / VF page was launched. To resolve this, the check has been modified to allow for external Cassandra.

Special characters escaped for use in "is in List" lookups
Resolved in Pega Version 8.7
After creating a specific criterion on any proposition using a string property, the "Is In List" operator, and a customer list with one value containing a "$", clicking save or check in resulted in the exception error "Problem invoking function: pega_decisionengine_propositionfilterfua.pzPropositionFilterMethodBody--(PublicAPI,ClipboardPage) java.lang.IllegalArgumentException: Illegal group reference at java.util.regex.Matcher.appendReplacement(Matcher.java:857) ". This has been resolved by escaping regular expression control characters in string replacement, which will allow the use of characters such as the $ sign for "is in List" lookups.

Interaction History properly saved when running strategy on a different data flow
Resolved in Pega Version 8.7
Customized Interaction History properties that had been added to pyInteractionHistoryConfiguration and pyDefaultWorkingSet and saved into the PR_DATA_IH_FACT table were not being saved properly after upgrading from 7.3 to 8.3. This was a missed use case and has been resolved.

Correct service instance name passed for data flow in DSMStatus
Resolved in Pega Version 8.3.2
When using the Connect-HTTP service "DSMStatus" to provide the node and status information as seen on the various tabs of the Designer Studio > Decisioning > Infrastructure > Services landing page, using DataFlow as the service parameter for the HTTP service method resulted in an empty response when the expectation was to get the information regarding the cluster details of Dataflow node type. This was traced to the service instance name not being parsed correctly when used for Data Flow services, and has been resolved by ensuring the correct service instance name is passed for this use.

Data Flow correctly handles table encountering null numeric columns
Resolved in Pega Version 7.2
When a data set was created on top of a exposed table which contains some null value in numeric columns, a Data flow executed using that data set used the value '0' instead of the expected null property. This was traced to the Data Flow batch run execution using the DSMClipboardPages, which weren't able to differentiate if a property was present or not and led to null being mapped to 0 in a numeric property. To correct this, the NativeSQLAPI will return null values as empty values when querying a DB and will not use them populate a DSM page or propagate them in the data flow.
