Default for 'database/oracle/allowOptimization' set to false in patches
Resolved in Pega Version 8.4.5
Recent patches contained an Oracle query optimizer implemented to prevent performance problems and other known Oracle bugs from impacting environments. However, while these changes were well intentioned, they either required providing additional database privileges or adding some configuration changes to provide the information needed in lieu of the privileges. This does not conform to the expected patch experience. To remedy this issue, the optimizations have been switched to being disabled by default in this release so that the behavior on upgrade is the same as prior to the applied patch release. If Oracle performance issues are seen, it is possible to enable the optimizations and provide either the needed privileges or configuration to make use of them. Please note the default remains 'enabled' for Pega 8.6.

Default compiler pool size increased
Resolved in Pega Version 8.4.1
An issue was seen where the nodes were continuously terminating and Stream service was not started. Error messages indicated a "WARN - Long running request detected for requestor", and that tasks were waiting for the generic object pool. Analysis showed that it was possible for a deadlock to form during the startup of the system or during the first few rule executions and compilations when there were more than five rules trying to compile. Once the variable LibraryMetadata.TypeEnvironment.resolver (ClassLoader) is initialized, the problem would resolve. To prevent the deadlock, the default compiler pool size has been increased from 5 to 10.

Pagination updated to resolve repeating Pulse notes
Resolved in Pega Version 8.4.1
After adding a case and entering 15 Pulse notes, scrolling down resulted in the notes being duplicated. Investigation traced this to entering more than 10 posts in a single interaction on a previously empty case when "Progressive pagination" was enabled for the repeating dynamic layout. On Private Edit, if the pagination was changed to "NONE" then the issue was resolved. Pagination depends on the pzPagingStartDateTime property, which is set on D_pzFeedParams, but since there were no results in this scenario this property was not being set. To resolve this, an update has been made so that pzPagingStartDateTime will be set if it is empty.

Support added for custom portal with temporary work object
Resolved in Pega Version 8.4.1
After creating a screen flow with temporary work object in a custom portal, entering some data and clicking caused the screen to be blank after browser refresh. The same process from Designer Studio or the Case Manager portal worked as expected. Investigation showed that SPA applications with displayonpage actions was sending empty parameters to render the harness due to the 'doUiAction' activity clearing additional pages for single frame portals. To resolve this, the 'when' rule in step14 has been updated to support a custom portal and temporary work object.

Added handling for clustered index on the pr4_rule table during migration
Resolved in Pega Version 8.8
When attempting to migrate the rules schema to RULES85 and temp data schema DATA85, the upgrade was becoming stuck in a loop while working to generate declarative indexes for Rule-HTML-Paragraph. Investigation showed the infinite looping happened only for classes mapped to the pr4_rule and with instance count of more than (num of threads * batch size). This was due to the presence of a clustered index on the pr4_rule table causing the resultset to return an infinite number of records in SQLServer, and has been resolved with an update to leverage the total record count to iterate the resultset instead of depending on the resultset.next().

Rest connector passes RequestAttachmentPage to child requestor
Resolved in Pega Version 8.8
While invoking the Rest Connect from a data page, the error "InboundMappingException: Exception occurred while mapping incoming response" was generated. Requests with "Content-type:multipart/form-data" require "pyRequestAttachmentPage" or "pyResponseAttachmentPage" to be populated with correct values. When Rest-Connector was executed in parallel, those pages were not copied to the child requestor and the rest call executed from the child requestor did not have correct header and body. To resolve this, MethodConnect.java has been updated to correctly pass pyRequestAttachmentPage to the child requestor.

Handling added for Model level Data type empty values
Resolved in Pega Version 8.8
After update, the Email Intelligent Virtual Assistant™ (IVA) was not able find the proper response for the real-time incoming emails but was able to find the topic and response when running it from Dev Studio and Prediction Studio. This was due to an edge case where the model datatype page list property was present on the text analyzer rule and a page was present in it, but the property pyName which actually holds the data type (body, attachment, all) was not present in the page. This has been resolved by updating the system to add 'all' as the datatype if the pyName is blank (null or empty).

Save works on Ajax container without Dynamic container
Resolved in Pega Version 8.8
After opening a work object and making changes to a required field, pressing the save button did not give any visual indication that the save was performed. Hitting cancel generated a dirty pop up saying changes will be discarded, indicating no save was done. When an Ajax container is configured without a Dynamic Container, all the content is rendered inside a fieldset tag instead of a form tag. While performing the save, the API was looking for the form element in the document and could not find any, and the save failed. This has been resolved by updating the submitWhenFail() API to handle both fieldset and form elements in the dom.

Conditional handling added for perceived invalid valuelist reference in design time
Resolved in Pega Version 8.8
After adding a value list property '.pyDateTimeValue(2)' in a section configured in the view editor, the design time error "config issue" was shown. There were no errors at run time and the application's behavior was correct. Changing the subscript of the value list property to (1) ran without an error. In this scenario, the actual usecase configuration will populate .pyDateTimeValue(2), but the view editor believed there was an error in the section because there was no reference to pyDateTimeValue(1) first. This has been resolved by conditionally changing the pyValue to a template property in design time when a perceived invalid valuelist reference is provided as property in the panel.

BAC handling added for calling StartNewFlow activity from UI
Resolved in Pega Version 8.8
After modifying the pycaseactionarea submit button to call a flow that uploads a PDF to a third party system using the order action 1) Finish Assignment; 2) Call an activity and inside the activity call startflow to initiate the integration; and 3) Launch local action, clicking the button to finish the assignment showed only the first local action instead of the expected behavior of having a modal appear to the user to confirm that their file was successfully uploaded. An access control error also appeared. This was traced to the registration details being removed after generating the pdf with an activity running on a different thread, and has been resolved by adding a flag tools.putParamValue("skipResetQueryStringRegistration",true); in pzCreatePDFHarnessWrapper to avoid wiping the registration details and skip resetting the query string registration during the process.
