Corrected layout group overlapping content
Resolved in Pega Version 8.3.5
When an editable Table with Master Detail Edit has a section that contains a Layout group (Tab) inside the Master Detail Flow Action, if there are more layout group headings than that can be contained in the screen, a left and right arrow are displayed to toggle between headings in the layout group heading bar. However, timing issues sometimes caused the contents of the layout group to overlap on top of the content below the layout group and the screen was freezing with a loading icon. This was traced to console errors, and has been resolved by adding an 'undefined' check to prevent those errors.

Performance improvement for Application Save: Node Level Data Pages
Resolved in Pega Version 8.7
As part of new functionality introduced in 8.3, data types defined in the application record will be turned into data objects on Application save. As part of this process node level pages are invalidated and reloaded and there is an explicit commit that marks the Application record as dirty and sends any calls for the application record to the database for fresh records. In a multi-node environment, the number of queries to get the application record being saved became exponentially higher and performance impacts were seen. This has been resolved by updating the system to skip eager loading of the data page definition when an access rule or application definition is saved.

Index table correctly populates after migration
Resolved in Pega Version 8.7
After creating a product file with work instances, only some records were populating in the index-workpartyuri class through index rule. Investigation showed that if the IDs specified for the Work Range started with the same digits as were seen after the case prefix (e.g. W-1, W-1000, or W-22, W-2201) then only the indexes for cases that start with W-1 or W-22 were included in the export. This was traced to a step in AddPartyIndexWhenCondition where the EstimatedWorkPrefix local variable was calculated: the java step extracted anything that was the same from the start of the To and From range without taking into account the possibility that some digit characters after the "-" could be the same. To improve the accuracy of the prefix estimation, "-\d" will be used to make an educated guess.

Handling added for multi-file upload of duplicated files
Resolved in Pega Version 8.7
Attaching the same file multiple times during a single upload caused some of the duplicated files to not be included. The issue was not seen when attaching the same file multiple times but in different attempts. The exception "Can't continue with file attachment. FileData.xlsx is missing and might have been quarantined by anti-malware software" was logged. This was caused by the files being uploaded without updating filenames to have a unique ID, so multiple files with the same name were overwriting the previous file. This has been resolved by setting the appendUniqueIdToFileName parameter to true in the upload request so each copy of the filename is treated as an individual file.

Stricter criteria set for reusing an SSAExecutionContext
Resolved in Pega Version 8.7
After a Strategy was configured with an existing Proposition Filter and the Explain Results box was unchecked, executing the strategy resulted in the error "Stack is empty, cannot pop any more frames". Investigation showed that the SSAExecutionContext object was reused across the two criteria evaluation in Proposition Filter rule: this works well as long as the input is the same across the two evaluations. However, the SSAExecutionContext object also stashed a reference to a PublicAPI object which became stale in the second evaluation and caused the empty stack issue for the given scenario. This has been resolved by providing stricter criteria in deciding when an SSAExecutionContext can be reused or not in the case of Proposition Filter rule.

Guided Tour working from Actions menu
Resolved in Pega Version 8.7
After updating from Pega 8.4 to Pega 8.5, "Manage a Guided Tour" was no longer working under a local action when called from the Actions menu on a work object. An unspecified error message appeared in the tracer. Investigation showed there was a null pointer error caused by the menu being invoked on an invalid page, and this was traced to updated authentication requirements: registration at the portal is not reliable as it is thread-scoped and run only once. The thread name is not guaranteed to stay the same so subsequent invocations of the tour activities failed. This has been resolved by modifying the call registration function to handle the security issues related to the generation of the menu path.

CheckFlowDependencies updated for auto-instantiated child cases
Resolved in Pega Version 8.7
A parent case with more than one child case was producing an unexpected behavior during the child case creation process. The first child case was instantiated at the correct point of the case stage based on its dependency condition, but the following cases were instantiated at the same point where the first child case was created irrespective of the dependency conditions defined in the other child cases. Investigation showed that the pxCheckFlowDependencies activity called from the Resolve activity was removing the named pages "pyTopCaseMap" "pyTopCaseWork" which are required for starting and validating configured auto-instantiate child cases in the pzCanStart function. To resolve this, an update has been made to CheckFlowDependencies which will use the activity "pzResolveCaseHierarchyMap" for removing the "pyTopCaseMap" and "pyTopCaseWork" pages based on DependencyType.

Restored local blocking queue cache
Resolved in Pega Version 8.7
After update, it was not possible to bring up secondary VBD nodes after restarting. Investigation traced this to earlier work done to resolve a memory leak issue, in which stale entries for local blocking queues were removed from cache. This resulted in modifying the queue listener logic to use "cache.getQueueIfPresent(jobId)" instead of "cache.getQueue(jobId)". Because the listener was not creating the cache if it was not present and the cache which held the local blocking queue didn't have the entry for the current remote execution job ID, the caller of the remote execution on Node2 ended up in blocking state forever, waiting on the local blocking queue. To resolve this, the code has been updated to ensure the blocking queue is created and stored in the local queue cache before publishing the remote job message.
