ExpandStream called before Page-Merge-Into to ensure correct merge
Resolved in Pega Version 8.4.5
The Page-Merge-Into method was not merging the source page into the target page when the use case was run without tracer, but merged properly when run with tracer. This was traced to an intermittent issue with expanding properties, and has been resolved by calling expandStream on the source property if it is unknown prior to checking if the source and target properties are merge compatible.

Archiving updated to include pxobjclass in CTE column list
Resolved in Pega Version 8.4.5
After enabling the case archival feature on a casetype, cases were getting stuck in the Archive-Ready state while being archived, and a 'column not found' error was seen. Investigation showed that the generated SQL statement used to retrieve the resolved case instances used a common table expression (CTE) whose columns were inskey, insclass, and parentinskey, and the query that referenced the CTE was attempting to compare the column pxobjclass when pxobjclass did not exist in the CTE's column list. To resolve this, the CTE column list has been updated to pzinskey, pxobjclass, and parentinskey to prevent the 'column not found error' from occurring, and the query that referenced the CTE was also updated to use the correct column names and aliases.

Methods updated to prevent rounding of JSON response decimals
Resolved in Pega Version 8.4.5
When using a REST connector for an outside service, precision numbers in the JSON response were being rounded or truncated when parsed for the DataSource page. For example, a JSON message with a value like 6045.900000000000000001 became rounded to 6045.9. This happened in both methods used for fast and non-fast processing, and has been resolved by treating the decimal value as a string and then creating a BigDecimal object out of it to avoid truncation in the fast processing scenario, and by adding mapper.enable(DeserializationFeature.USE_BIG_DECIMAL_FOR_FLOATS); for the non-fast processing scenario.

Race condition resolved for input/output pipe streams
Resolved in Pega Version 8.4.5
Writing to S3 using file data set was failing with the error "Exception occurred while uploading file". The system was relying on PipedInputStream for getting the data from the file while uploading, which needs to be connected to PipedOutputStream which holds the data to be uploaded. Investigation showed a race condition was occurring where for some use cases the reading of inputStream was happening before the connection of I/P and O/P streams, resulting in a "Pipe not connected" error. This has been resolved.

Java Bean import updated to handling differences in Java 7 and Java 8
Resolved in Pega Version 8.4.5
The behavior of the java bean Introspector class is inconsistent across different versions of the JDK when detecting indexed properties built off of java.util.List objects, causing Java Bean import to generate differently in Java 7 and Java 8. This has been resolved by updating PRIndexedPropertyDescriptor to better handle this JDK difference by resolving indexed read and write methods manually using simple reflection.

GRS support added to Display name and Reply to for SendEmailNotification
Resolved in Pega Version 8.4.5
After upgrade, it was not possible to send email notifications when using a Datapage property in the email account rule. Investigation showed that there was a custom activity being used to call the SendEmailNotification activity and set the pyNotifyAccountName value as email account name by enabling Pass current parameter page, and the custom call was not functioning due to the SendEmailNotification activity being completely refactored in recent versions of the platform where GRS support (which was not a documented feature) was removed. For better backwards compatibility, this issue has been resolved by adding GRS support to Display name (pyFromFullName) and Reply to (pyReplyTo).

Tracelist cleared to address parser exception in REST Service
Resolved in Pega Version 8.4.5
In a requestor pool of mixed types, HTTP and REST, the alert data was not initialized properly if there was a parse exception due to invalid data in the incoming payload. For example, last_input, first_activity, and last_step could all be left over from the prior HTTP service request. This was caused by the system pulling in seemingly unrelated activities for the "Last activity called" in the stack trace of a service when a single alert was created by two different service types which were sharing the same package, and has been resolved by explicitly clearing the tracelist for the service to prevent inaccurate information being reported in the logs.

Default sorting with Pagination, Data Page and Report Definition corrected
Resolved in Pega Version 8.4.5
After configuring a section with the table sourced from a data page and personalizing the table with the pagination and sort-by features available in a report definition, the table content sourced with the data page was not sorting the data. This has been resolved by updating the pxRetrieveReportDefinition activity so that the sort order for queryable data pages will not be reset for a first-time request.
