Unit testing validation relaxed for external input strategy
Resolved in Pega Version 8.3.2
When trying to test a strategy, the testing transform had to exist in the same ruleset/version as the strategy or it would not resolve. Investigation showed that because the artifacts were in a different ruleset and version build on top of the application that the testing strategy belongs to, validation failed because it was using the platform based ruleset validation. This was a missed use case, and has been resolved by relaxing the validation for external input strategy so it does not take into account the ruleset and version of it. This same change has been applied for referenced data transforms.

Corrected EditElement disappearing after DDR import
Resolved in Pega Version 8.3.2
After importing a DDR to a 'treatment', the section disappeared. Because the treatment decision data rules are created in the top level SR class, when the treatments are exported from these rules, the pyIssue and the pyGroup classes are empty in the exported CSV. When new treatments were added or existing treatment are modified in the CSV and imported, the pxObjClass for the treatments was set to Data-pxStrategyResult as the pyIssue and pyGroup were empty in the imported CSV. To correct this, pySelectedClass will be set to the propositions instead of pxPage.pxObjClass while importing.

Data join conditions representation updated to avoid overwrite
Resolved in Pega Version 8.3.2
After upgrade, a Data join component on the Strategies was not working as expected, especially the ones using the DateTime function. If the data join conditions were swapped, i.e the DateTime function was not the last criteria, the strategy outputs were correct.Investigation showed that the implementation used a map to represent pairs of left and right expressions which caused conditions rows with the same leftExpr to end up overwriting one another. This has been corrected by fixing the representation of conditions of a Data Join to a list of tuples which eliminates the possibility of one condition overwriting a previous one.

Predictor handling updated for Versioning Adaptive Model
Resolved in Pega Version 8.3.2
When attempting to update an adaptive model in a branch after it had been versioned, errors were observed on Predictor Type data that had not changed from the previous version. This was traced to an issue in the Adaptive Model rule UI in both Prediction and Dev Studio where if a non-default predictor type is selected, it would show in the UI but not be saved to the database. No error was shown. This silently led to the unexpected and incorrect data being stored with the result that once data had accrued, the rule could not be saved/saved-as due to validation believing the predictor type of a predictor with data was changing. To resolve this, rules have been updated so that the system will no longer override the predictor type of a predictor being edited when it is solely the predictor type that is changing.

Rule creation logic updated to include creation branch
Resolved in Pega Version 8.3.2
When trying to create a new adaptive model rule in Prediction Studio, the “Create” button was not activating. The adaptive model rule was being saved in a branch ruleset, and investigation indicated that the deactivated button could be traced to the lack of an open ruleset version available even though the intention was to create it on a branch. This has been resolved by modifying the rule creation logic to incorporate the branch for creation.

Deadlock in static Initialization of IntList resolved
Resolved in Pega Version 8.3.2
JVM Deadlock was seen related to the static Initialization of a subclass field in class com.pega.decision.strategy.ssa.runtime.collections.api.IntList . Thread dumps showed threads in RUNNABLE State that were parked to wait for class initialization, and this was traced to a missed sonar alert which failed in multi-threading. To resolve this, the system handling has been updated to prevent potential deadlock.

Updated VDB Statistics rendering to compensate for Google Chrome changes
Resolved in Pega Version 8.3.2
The Statistics overlay was not rendering for VBD planner in Google Chrome. Investigation showed that the Google Chrome browser (v.77) was misfiring one of the mouse events due to changes in the browser, and the handling has been updated to resolve this issue.

Prconfigs added to support Cassandra Speculative Based Execution
Resolved in Pega Version 8.3.2
In order to achieve high availability for Cassandra, prconfigs have been added to support speculative execution. The available prconfigs will enable it, and set maximum number of executions and delay before the next execution is launched.The prconfigs are: dnode/cassandra_speculative_execution_policy dnode/cassandra_speculative_execution_policy/max_executions dnode/cassandra_speculative_execution_policy/delay

Internal Cassandra memory leak fixed
Resolved in Pega Version 8.3.2
A memory leak was found on internal Cassandra that caused temporary log files to fill up the heap. This has been resolved by updating the system to ignore non-log files and properly increment the index.

All interactions visible in "Latest Responses" for ADM
Resolved in Pega Version 8.3.2
Interactions were not visible in the "Latest Responses" section of the Model Management landing page for Adaptive models if the requests were stored on multi-node systems. This was due to the system fetching the Last Responses using a list of server nodes built using a version of deployment.getClusterState(tools) which gave only the ADM nodes list instead of all the ADM nodes both client and server. To resolve this, the system has been updated to use ServiceRegistry to get all of the data flow nodes and get the last responses from each of them.
