Email Parser updated with entity models and datatype casing
Resolved in Pega Version 8.8
When the email bot receives a message, all of the content plus the appended disclosure statement added by the mail server is considered. This was causing issues when words in the disclosure matched words added in the actual email body as keywords, causing the email bot to pickup multiple categories matching these words and not routing the service case appropriately. This has been resolved by adding AnalysisType.ENTITY in the analysisType list for pre-processing models and updating the logic to find out if entity extraction is selected or not (without using the analysisType list). In addition, an issue where pxEmailParser model was not running in the email channel due to an issue with preprocessing model datatype casing has been resolved by updating ExecutePredictionInPRPC to lowercase the datatype after reading from the text analyzer rule page, and then perform the comparison.

Cassandra retry policy enanhancement
Resolved in Pega Version 8.2
When configuring the datastax client for Cassandra, it is possible to specify a retry policy. By default the DefaultRetryPolicy is used. While a retry was always attempted on client timeout with this retry policy, a retry on server timeout was only attempted in a limited set of circumstances. This code indicates that for a retry: - The number of received responses is at least the same as the number of required responses - The retry will be done to the same node, not a new node This use makes sense if consistency is set to QUORUM or higher, but it does not make sense for consistency ONE. To resolve this, a new retry policy has been added which will retry in this scenario a configurable number of times. The retry policy and the retry count will be controlled by prconfig settings: prconfig/dnode/cassandra_custom_retry_policy/default - True/False (default: False) prconfig/dnode/cassandra_custom_retry_policy/retryCount/default - >= 0 (default:1)

RUTA handling improved in Prediction Studio
Resolved in Pega Version 8.8
Out of memory errors were seen when using natural language processing (NLP). Investigation showed that certain Apache Rule-based Text Annotation (RUTA) scripts had disjunctive rules which were not able to handle certain types of texts having base64 characters which were introduced in emails via attachments, images, logos etc, and which caused excessive system loads. This has been resolved by modifying the RUTA handling in the Prediction Studio settings to better manage the scenario.

Updated cache key generation for ROPC
Resolved in Pega Version 8.8
After configuring outbound email functionality using MSGraph with OAuth 2.0, sending the emails failed consistently following passivation. Running "Test connectivity" in the Email Account data instance then seemed to restart the functionality and the automation "Create And Send Email" subsequently worked. This was traced to a missing username in the cache key generation for the Resource Owner Password Credentials (ROPC), which caused the same token to be fetched when attempting to dynamically generate different usernames, and has been resolved.

Updated default portal harness handling for switching applications
Resolved in Pega Version 8.8
After opening the user portal in a new browser tab through interaction with the search, a blank screen was presented when attempting to switch applications via the operator menu. Performing the same actions in the main / originally opened portal worked as expected. This has been resolved by creating a new section pyPortalNavigationHeader in pzPortalNavigation which has an action to open the harness which is available first in D_pzDynamicnavigationpages. This new section has been marked as available to allow local modification of the default harness for sites not using dynamic navigation.

Performance and thread-handling improvements for SSA
Resolved in Pega Version 8.1.8
The SecureRandom class was used internally by SSAExecutionContext indirectly via UUID generation. Because this exhibited performance issues on some Linux environments, UUID has been replaced with static AtomicLong. In addition, a memory leak was observed when the strategy (SSA) execution resulted in an exception, and the strategy template has been modified to gracefully shutdown the VM under all circumstances. Thread-safety measures have also been tuned to be more fine-grained to reduce the potential thread contention that was seen while borrowing the SSAInterpreter object from SSAInterpreterPool.

Schema name made consistent for DDL generation
Resolved in Pega Version 8.2
A platform upgrade failed if there were application schemas configured with a table configuration that specified a schema other than the rules schema. This was an issue caused by the generated DDL having the incorrect schema name for the table due to the name being hard-coded in the Data-Admin-DB-Table entry definition. The system was using this schema name to find the table and generate the correct changes, but the SQL statement used the table from the database connection instead of the override. When the XML that represents the difference between the "source" and "target" state is generated, the system is supposed to replace the schema name with the target schema name. However, if the source schema name is blank that step was skipped in order to defer to the connection for shipped tables. In order to ensure that the system can generate the correct DDL and complete the upgrade, the system will now always replace the schema name regardless of the source or target value.

Connector and Metadata wizard skip of renaming classes works for very large metadata in Chrome
Resolved in Pega Version 8.2
When using the Connector & Metadata wizard to generate Data mapping rules for Java Bean metadata with an imported jar containing a large number of metadata (over 5000 classes and properties), clicking on the option to skip renaming of classes and properties caused the browser to hang. This was traced to legacy code which was not efficient enough to handle this volume, and modifications have been made to avoid unnecessarily overloading the DOM and triggering onclick addEventListener events multiple times. This reworked skip function works smoothly with Chrome, but as yet does not work with the IE browser due to legacy coding and browser incompatibility issues.

Tab layout group handling improved
Resolved in Pega Version 8.1.8
A difference in scrolling speeds between left and right arrows and an issue with the cursor correctly being redirected to mandatory fields were traced to errors in the tab layout group handling. The right scrolling issue was due to the calculation for right tab movement being incorrect in certain resolutions with relatively positioned elements, and has been corrected. The cursor redirect was caused by an error in the layoutgroup focus when used inside a screen flow where the first focus goes to the screenflow navigation on load, and has been resolved by adding a try catch for an invalid selector in case of a div error.
