ExpandStream called before Page-Merge-Into to ensure correct merge
Resolved in Pega Version 8.5.4
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.

Oracle handling updated for upgrade DDL
Resolved in Pega Version 8.5.4
DDL generated for a Pega upgrade displayed the error "ALTER TABLE PC_ASSIGN_WORKBASKET DROP CONSTRAINT GETNEXTWORKINWORKGROUP" when trying to install. This was traced to a change made by Oracle for optimization, and has been resolved by updating the handling for primary key constraint and the corresponding index name.

Methods updated to prevent rounding of JSON response decimals
Resolved in Pega Version 8.5.4
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.

Zero Downtime Upgrade mechanism updated
Resolved in Pega Version 8.5.4
Scheduled Agents were running several times on each node when there were many executions scheduled for the same agent. This was due to the task derived from the agent's schedule not being unique to the agent, allowing the Zero Downtime Upgrade logic handling the insertion to restart agents several times while reacting to cluster topology changes. To resolve this and make the process more robust, the Zero Downtime Upgrade mechanism has been updated with better tracking and logging.

Queue processor correctly moves items to Broken Items
Resolved in Pega Version 8.5.4
When an exception occurred while Queue Processor processed an item, he queue item was not moved to Broken Items. The error " inconsistent datatypes: expected - got CLOB DatabaseException caused by prior exception" was generated. This has been resolved by modifying the NativeSQL builder and NativeSQLBatchExecutor to allow the batch of queries to be retried. Additional changes were also added for Oracle databases to identify the correct column types.

Tracelist cleared to address parser exception in REST Service
Resolved in Pega Version 8.5.4
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 8.5.4
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.

PEGA SOAP Service MTOM attachment handling updated
Resolved in Pega Version 8.5.4
After configuring a PEGA SOAP service with the Enable MTOM checked, sending a SOAP request with attachment to the service returned an invalid request error stating "Value of content length header is greater than zero - [762], but this request has empty POST". Investigation showed that when the input request reached the getPostBytes method and inputstream tried to read it, there were no available bytes and end of file was detected. This was due to the inputstream having already been read in getMultiPartSOAPHandler() method in FileUploadHandler class. To resolve this, the system will update an 'if' condition in getPostBytes method to skip reading the request attachment when contentType is "multipart/related".

Assistance and diagnostics added for issue with opening imported 'when'
Resolved in Pega Version 8.5.4
After upgrade, attempting to open rules that were developed on lower environments and then imported resulted in unknown errors. A workaround has been added to skip and log any corrupted property that might be interfering with the rule opening: enable Skip-Corrupt-Property to put this in place. To improve diagnostics, the new logger NBA-WME-DEBUG has been added. If the error continues after using Skip-Corrupt-Property, Skip-Corrupt-Property should be disabled and NBA-WME-DEBUG should be enabled and kept active until the issue occurs again.
