INC-125838 · Issue 561484

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.

Report Definition replaced with a data set for training the data and build model

Resolved in Pega Version 8.4.2

An issue with training the data and build model via an email or chat channel was traced in an exception in logs indicating the inability to execute a Report Definition. This can happen when UDF are removed/disabled in the database or in environments where functions are not allowed to read the blob for performance reasons. To resolve this, the Report Definition has been replaced with a data set.

DSS added to configure Dataset-Execute page handling

Resolved in Pega Version 8.4.2

When Kafka Data Set pages were saved to a data set with the Dataset-Execute method, there was is feedback if any of the pages were not successfully saved. Instead, the step always completes as successful. In addition, if any properties are added or modified by the save operation itself, those changes are not visible. This is due to the data set execute save operation saving pages as DSM pages to the data set. Due to the conversion of the pages, copies of the pages are used which do not reflect back any changes on the input pages. DSM pages are used by default because they are more lightweight than regular clipboard pages and therefore have potentially better performance. In order to allow the use of DSM pages to be customized, a new Dynamic System Setting: dataset/execute/save/statusFailOnError has been added. This can be enabled by setting it to true; it is disabled by default for greater backwards compatibility. By removing the DSM page conversion in the generated save code, changes to input pages will be reflected back if any are performed by the data set save operation, and the system will report back which pages are saved or failed by adding messages to the pages that failed to save. Performance may be affected with this change as regular clipboard pages are in general slower than DSM pages, however, that may be offset by removing the conversion to DSM pages process and will depend on the site configuration.

Modifications to getFunctionalServiceNodes process

Resolved in Pega Version 8.4.2

The count of the Interaction History write related threads was increasing rapidly and a stack trace indicated "waiting on condition" and "java.lang.Thread.State: WAITING (parking)" errors. Investigation showed that this was due to getFunctionalServiceNodes using Hazelcast to determine node status by making a service request on an installation with a very large number of nodes, causing thread locking. To resolve this, the implementation has been updated to avoid calling getFunctionalServiceNodes on save of Interaction History, instead using Cassandra and only calling getFunctionalServiceNodes on the master node, not on all nodes.

INC-128385 · Issue 564522

Behavior made consistent between SSA and legacy engines

Resolved in Pega Version 8.4.2

There was a behavioral disparity between the legacy execution engine and the SSA engine where the latter was not creating a new page when the index was one above the size of the page list. This has now been corrected in order to make the SSA behavior fully backward compatible with the legacy engine, i.e. a new blank page will be added to the list if the index is one above the size of the list.

INC-128898 · Issue 564692

Updated precondition checks for Tumbling Time data in event strategies

Resolved in Pega Version 8.4.2

Tumbling Time data keys in event strategies were not being properly executed when certain window configurations were used. This was has been resolved by turning off the optimalization of Cassandra reads for small windows when window size is not known upfront and set dynamically (set size by property).

INC-130037 · Issue 570959

Corrected caching sync for proposition filter

Resolved in Pega Version 8.4.2

Unit testing or a manual run of the generated strategy through next best designer was not giving the result, but instead was throwing a stale thread error. Investigation showed that the PegaAPI reference was cached in proposition filter at first execution and the filter was trying to use same reference for other further executions. This has been resolved by ensuring the cached reference is properly synced.

INC-130471 · Issue 569670

Null handling added for SSA parsing

Resolved in Pega Version 8.4.2

Strategy save was failing for the FormatDateTime expressions such as FormatDateTime(@addToDate(@getCurrentTimeStamp(),3,0,0,0),"yyyy",null,null) FormatDateTime(@addToDate(@getCurrentTimeStamp(),3,0,0,0),"MMM",null,null) FormatDateTime(@addToDate(@getCurrentTimeStamp(),3,0,0,0),"yyyyMM",null,null) This was due to the SSA engine not considering NULL to be a valid type-safe optimizable expression. To resolve this, the parsing process has been updated so that unsupported IL nodes (such as the node representing literal null) will cause the expression to fall back to legacy instead of failing.
