Installer files updated with class loader conflict resolution assistance
Resolved in Pega Version 8.2.4
When sending emails with attachments, errors were observed relating to a loader constraint violation indicating that when resolving interface method, the class loader of the current class and the class loader for the method's defining class had different Class objects for the type used in the signature. The resolution for this requires user configuration of the app server, and the following files for the install guide have been updated with the appropriate information:Deployment-guides-dita/install.ditamap Deployment-guides-dita/Content/Topics/app-server-config/creating-jdbc-driver-module-jboss-tsk.dita Deployment-guides-dita/Content/Topics/app-server-config/delegating-javax-activation-to-JRE-loader-tsk.dita

Added timeout handling for non-PRAuth servlets
Resolved in Pega Version 8.2.4
After logging in via external authentication service (SAML Single Sign On) and setting up a timeout in the access group RuleForm, when the user performed any action and the server identified the request to be timed-out, it was expected that a SAML request would be sent from the browser to the external Authentication Server (referred as IDP) and the flow would proceed from there. This worked as expected for a non-AJAX request. To resolve this, handling has been added for timeout when using non-PRAuth authentication services.

SAML data pages restored after passivation
Resolved in Pega Version 8.2.4
If login used SAML SSO, resuming the session after passivation resulted in missing or empty data pages when using an SAP integration with Pega Cloud. This was traced to a security change that modified the D_SAMLAssertionDataPage and D_SamlSsoLoginInfo data pages as readonly, causing them to not be passivated under these conditions. To resolve this, the data pages have been made editable so they will be restored as expected. This change also resolves any difficulty with SAML logoff activities in conjunction with SAP and Pega Cloud.

prproductmigration build.gradle updated for new mime4j asset name
Resolved in Pega Version 8.2.4
While running the getMigrationLog for ProductMigration script provided in the Pega 8.2.2 media files, errors appeared referencing "NoClassDefFoundErrors when running getLogs". This was caused by the referenced class not being found on the classpath: the version of the included jar did not include the class needed due to Praxiom's default version being updated to use a new version of mime4j that required an asset name change. To resolve this, the mime4j asset name in prproductmigration build.gradle has been updated to pick up the correct version of the dependency for Praxiom.

Update Handler will not run during migration
Resolved in Pega Version 8.4.1
Rolling restart of DataFlow, ADM ,VBD, and Util Tiers failed with a PENDING_JOINING error after an in-place upgrade. This was traced to the logic for the update timing: when nodes start after an upgrade from 7.x to 8.x they will migrate data flow runs. Migration happens on only one node, and while it's in progress the other nodes will wait until migration finishes before they come up. At this point the state of the data flow services will be 'PENDING JOINING'. The issue is that while migrating runs, the Data Flow Update Handler was triggered to validate whether there were nodes available on the service the run belongs to. This call can cause the corresponding data flow service to be initialized, but the call will be blocked since all services wait for the migration to end. This resulted in a deadlock which prevented all nodes from coming up successfully. To resolve this, the process has been updated to skip the update handler during migration to avoid triggering the initialization of client services that are waiting on the migration lock.

DDS service will not run Hazelcast check if external Cassandra is configured
Resolved in Pega Version 8.4.1
Services were not responding, and thread dumps seen in the logs indicated that a large number of threads were waiting for one to come back from getting the cluster state for a DSM process. Investigation showed that the threads were waiting for a Hazelcast response about the cluster state. However, since a Hazelcast call is not needed when Pega is configured with external Cassandra, the DDS Service code has been changed to not to check for candidate nodes if configured with external Cassandra cluster.

Corrected calculating propensities
Resolved in Pega Version 8.4.1
Several PMML models designed to compare the outcomes to a control dataset experienced an issue where the probability scores in Pega did not match the original control dataset. The PMML model was also tested using KNIME; those results matched Pega but not the original control dataset. Investigation showed that the JPMML evaluator contained outdated code, and the incorrect calculations have been resolved.

DataSet preview will use date instead of datetime
Resolved in Pega Version 8.4.1
While using a DataSet preview functionality, the date appeared as reduced by one day. This has been resolved by parsing date as 'date' instead of 'datetime' to avoid issues with timezone interactions.

Added tokenizer for KeyWord-Based Topic Detection phrases
Resolved in Pega Version 8.4.1
KeyWord-Based Topic Detection was not Working for "Enrollment/Re-Enrollment" as a word, for example a categorization model with the text 'This is an email related to Enrollment/Re-Enrollment'. To facilitate this use, a tokenizer has been added to break 'should',' must', and 'and' words into components for a taxonomy match.
