Read operations updated for Datastax 3.1.x use
Resolved in Pega Version 7.3.1
In the 3.1.x Datastax driver reads are no longer retried by default. Therefore, the read operations have now been explicitly marked as idempotent to force the Datastax driver to retry timed out reads.

Timeout error resolved for write future
Resolved in Pega Version 7.3.1
With retries enabled, the write future was timing out before retries could be completed. This has been fixed by removing the timeout on the write future since timeouts will be caught using Datastax driver exceptions.

Facebook connector refined to handle page deletion while the AADrivetech is active
Resolved in Pega Version 7.3.1
A Facebook connector trying to connect to a invalid page was causing out of memory errors. In this scenario, a Facebook Page that was no longer required was deleted but the AADrivetech Facebook connector was left running. This connector, in its attempts to contact the Facebook page and retrieve the getFrom parameter which was now null, started to consume resources on the node leading to the outage. To solve this, the code has been modified to not expect the user name to always come from Facebook but instead put in an anonymous name if the page disappears.

Backwards compatibility enhancement for @when() validation
Resolved in Pega Version 7.3.1
After upgrade, a Strategy rule which referred a 'when' with the syntax @when(isOnlineApplication) was failing with design time validation saying that when rule was not found in the SR and instead it had to find it in the Customer/Applies to class. For the @when() issue, the root cause was that the validation context of @when() was switched from Applies-To class to the Step Page class due to a change in the core engine. The behavior of expression parsing for when rule calls was changed in release 7.2. It used to take the Apply-to class to validate the existence of the rule, but not it is taking the Step Page class. And Strategy rule doesn't push/pop stackframe due to performance reasons, thus StepPage on stack for Strategy is always the same as Primary page. For greater compatibility, the system will set the PageContextClass to the Apply To class so the expression parser can validate the setup which is expected at run-time.

CLOB type handling enhanced in Marketing
Resolved in Pega Version 7.3.1
Pega Marketing uses the out-of-the-box DSM activity pxRunDDFWithProgressPage for triggering Data flow runtime. After upgrade in DB2 environments, the DF execution completed but the activity returned a failure. It was found that if a CLOB column is present in the filter of a NativeSQL object invoked from an activity, the status had an error message even though functionality was fine. To ensure consistent behavior, CLOB has been added to supported data types so the severity of the exception can be changed so as to not show error message in activity's status.

IH Summaries correctly loads aggregated count
Resolved in Pega Version 8.4.2
After the IH Aggregated DataFlow has processed more than 34 million records from an Oracle database, the IH Fact table contained only ~120,000 records. Running a browse on the pxInteractionHistory DS resulted in an infinite loop. Investigation showed that this was caused by the handling of Oracle timestamps: using Pega DateTime in query parameters generated Oracle DATE instead of TIMESTAMP, causing all query parameters to be rounded to the second and interfering with the IH pre-aggregation. This has been resolved by updating the handling.

Null check added for Entity Extraction result
Resolved in Pega Version 8.4.2
Training data for an Entity Extraction model was not getting distributed correctly, as per the given % data. This was due to the result of the Entity Extraction result being null, and has been resolved by adding a check that will consider detected types as primary candidate for grouping if the result column is null.

Ignore Case feature updated
Resolved in Pega Version 8.4.2
In Pega Marketing 8.4 on the Action rule form, configuring an eligibility criteria and selecting the option for the comparison to ignore case did not copy this part of the criteria to the back proposition filter rule, so the case of the comparison was not ignored at runtime. This has been corrected.

ResolveFTCR flow Draft mode turned off
Resolved in Pega Version 8.4.2
When using the FastTrack Change Request functionality of Revision Manager 8.3 the submission was going to Pending packaging instead of Resolved-Completed with the error "flow is in draft mode; it cannot be executed". This was due to pxResolveFTCR flow having been checked in with Draft mode turned on, and has been corrected by turning Draft mode off.

PropertyToColumnMap made more robust
Resolved in Pega Version 8.4.2
The DF_ProcessEmails dataflow was intermittently failing with a StageException error. This was traced to schema changes being propagated asynchronously by system pulse, which seem to have caused PropertyToColumnMap to cache stale schema. To resolve this, if the property mapping is not found the first time, the system will make a second attempt to get the mapping. Additional logging has also been added for better diagnostics.
