Handling updated for redirect URI construction
Resolved in Pega Version 8.4.2
The redirect URI for an ODIC authorization request to IDP from Pega was truncated, resulting in an incorrect redirect URI. This was traced to the App alias feature was introduced in 8.4 which appends /app/ to the context URL. While constructing OpenID authorization request, the redirect URI was constructed from current login context. In the process of removing the app alias from the URL, a conflict was seen when the server name contained the word "app" in it. To resolve this, the app alias handling has been updated.

Attachment Migration tool updated for improved node crash handling
Resolved in Pega Version 8.4.2
During attachment migration from PegaDB to the S3 repository, a stream node crashed and left queue items in the queue. When the node restarted, these items were migrated successfully to S3. However, a manual restart of the attachment migration tool then ended up duplicating the items already successfully migrated. As part of handling the duplicate attachments, files with 0 bytes were created in S3 and the zero byte link was updated to the Data-WorkAttach-File instance. In order to handle this scenario, an enhancement has been added that will skip migrating attachments already migrated to repository or those having an empty attachment name.

Handling added for Decision Table test case with "call"
Resolved in Pega Version 8.4.2
Clicking on the Convert to test button to launch a Test Case rule form did not load all of the options to create the UTCs, and the screen seemed stuck on the message “Loading..”. This was a corner case that happened when the decision table's return value had "Call" in it: the table believed there was the need to call another decision table, which was traced to "Call" being present on the RUT's label values. To resolve this as avoid regressions, quotes have been added to the returned value so that the value is picked instead of trying to call another decision table.

Field added to configure jFrog artifactory context root
Resolved in Pega Version 8.4.2
After configuring a JFrog repository rule and successfully testing the connection (from the rule configuration page), attempting to browse the remote repository from the "File Storage" landing page did not work. Investigation showed that ArtifactoryStorage.java was automatically appending "/artifactory" to the host name of any artifactory repo instance, causing a mismatch with the configured URL. There was a workaround of configuring the hostname with a context root, but this issue has been resolved with an additional ruleform field to specify the context root. Leaving this field blank will create the url using strictly what is contained within the host name field, while populating it will construct the url as follows:url + contextRoot + "/artifactory" This field will default to "/artifactory" to help preserve backwards compatibility.

Parameters added to protect font size in HTML to PDF conversion
Resolved in Pega Version 8.4.2
Pega uses the pd4ml external library for HTML to PDF conversion. As part of this, the adjustHTMLWidth API was called to avoid truncation issues, but this resulted in font-sizes not being preserved in the exported document but rather changed as necessary to fit in the PDF. In order to support preserving the font size during export, the pyPDFSettings datatransform will call the protectPhysicalDimensions API along with setHTMLWidth, and avoid calling adjustHTMLWidth. With this change in place, any content width should not be set explicitly to some value as it may lead to truncation if the space is not sufficient. If there is no width set, text will wrap automatically. In case of tables with large number of columns, truncation issues may be seen: to avoid such issues, pass a larger htmlWidth value so that table will be reduced in size and in the rest of the page, font-sizes are preserved.

Updated Email Listener sentence detector logic
Resolved in Pega Version 8.4.2
When the Email Listener encountered a specific XLSM attachment, it became hung up in Running state. The email was marked as read in the email box, but the Email Triage case was not created and the Listener did not process subsequent emails. If the Listener was stopped, it would not restart. Investigation showed that multiple numbers of \n followed by a repeating sentence in the document caused the pointer to lag behind and create multiple annotations pointing to the same offsets. This in turn caused the further analysis to run in a really large loop, causing the slowdown. This has been resolved by updating the logic of the post processing for the sentence detector so that the duplicate annotations are not created.

Resolved OAuth2 mobile app loop
Resolved in Pega Version 8.4.2
When a Pega OAuth2 authorize endpoint was invoked and the redirect URI contained "app", a loop was created where the system attempted to fetch the app alias from the state parameter value and was redirected back to itself. This could sometimes result in inconsistent mobile app styling. Investigation showed that a certificate with keyword app that was picked for the redirect URI could have the key word assumed to be the app alias context, so a workaround was to remove the app keyword. To resolve the issue, the system has been updated to look for the app alias only in the state parameter rather than perform a string contains check on the entire query string.

Corrected report with combo chart in Case Manager portal
Resolved in Pega Version 8.4.2
After adding the required columns a report in the report viewer and then adding a combo chart and dropping the summarized column on the y-axes and group by column on X-axis, clicking on "done editing" generated the error "pyUI.pyChart: You must have at least two Aggregate Columns in the chart series .pyUI.pyChart.pyDataAxis(1).pyChartOutputType: A Combo chart requires at least 1 Chart Type be a Column". Investigation showed that the second DataAxis page was getting deleted in the pzCleanChartDataAxis activity, causing the validation to fail. This has been resolved by adding a 'when' rule to "pzChartIsSingleY" that checks for "SingleYAxisClustered" chart and refers the same in pzCleanChartDataAxis to skip the data axis deletion.

Toggles added to allow file listener performance improvement
Resolved in Pega Version 8.4.2
In order to offer flexibility in improving the performance of file listener CPU usage while processing intake files, rsf.setSaveIntermediateState( true ) has been replaced with rsf.setSaveIntermediateState( listener.getListenerProperties().getAttemptRecovery() ) in FileActionImpl. This change allows the option of not selecting the setting for attempting recovery on the file listener rule-form, which then would skip the intermediate save state normally performed per record/per file in case recovery is needed, thereby speeding up the processing. A toggle has also been added to see whether the system should bypass the ListenerState check at the end of each record. To use this, set the Dynamic System Setting "listener/skipListenerStateCheck" in the "Pega-IntegrationEngine" ruleset to true.Additional Installation Instructions Please create/set the Dynamic System Setting "listener/skipListenerStateCheck" in the "Pega-IntegrationEngine" ruleset as true.
