PropertyToColumnMap made more robust
Resolved in Pega Version 8.1.9
The DF_ProcessEmails dataflow was intermittently failing with a StageException error. This was traced to schema changes being propagated asynchronously by system pulse, which seem to have caused PropertyToColumnMap to cache stale schema. To resolve this, if the property mapping is not found the first time, the system will make a second attempt to get the mapping. Additional logging has also been added for better diagnostics.

Behavior made consistent between SSA and legacy engines
Resolved in Pega Version 8.1.9
There was a behavioral disparity between the legacy execution engine and the SSA engine where the latter was not creating a new page when the index was one above the size of the page list. This has now been corrected in order to make the SSA behavior fully backward compatible with the legacy engine, i.e. a new blank page will be added to the list if the index is one above the size of the list.

Handling improvements for commit logs
Resolved in Pega Version 8.1.9
The ADM commit log logs the number of unconsumed messages that are going to expire. In certain circumstances, it can include unconsumed messages that are not going to expire in the count. Because they are not expired and removed, the environment was running out of disk space due to the ADM commitlogs table growing larger than expected and performance issues were seen. To resolve this, a new adm_commitlog.adm_responses_commit_log_date_tiered table has been created, with a default_time_to_live of 24 hours. DateTieredCompactionStrategy has been set with max_window_size_seconds as 24hrs and tombstone_compaction_interval as 24hrs.

Performance improvements for Test Strategy data flow
Resolved in Pega Version 8.1.9
In the Test Strategy panel under Single case -> "Settings", selecting the "Data flow" option and choosing CustomerData dataflow was taking an excessive amount of time to run on a system with an extremely large database. To improve performance, two areas have been addressed: 1) the default behavior for record key suggestions in the test panel has been modified to collect only the ID as the additional data is not necessary at that time; 2) a DSS has been added that will opt out of reading and collecting the customer IDs in order to minimize data stored on the clipboard.

Strategy handling updated for very large systems using IH summary
Resolved in Pega Version 8.1.9
When a Strategy in a Real-time dataflow used IH Summary on a system with more than 5000 groups for one eventKey, the message "Error retrieving aggregates from Cassandra KVS" intermittently appeared. Investigation showed that if the number of result rows was greater than the FETCH_SIZE (set to 5000), it meant another read to Cassandra was required and an exception was generated. To resolve this, updates have been made so that instead of returning maps, the system will return iterators and change them to map on the calling thread.

Added handling to force text area maxlength in Microsoft Edge
Resolved in Pega Version 8.1.9
When using the Microsoft Edge browser, it was possible to continue entering characters in excess of the value set for the 'max characters' property. Investigation showed that the Microsoft Edge browser does not honor the maxlength attribute on text area; to resolve this, logic has been added to restrict the user from entering extra characters above the max limit.

Focus persists for embedded Tab Group layout with section refresh
Resolved in Pega Version 8.1.9
When a Tab Group Layout was configured with multiple sections using multiple input elements including one with a 'Refresh this section' action, using the Tab key to reach the input element, make a change, and hit Tab again caused the focus to reset to the top input element. This has been corrected.

Updated handling for checkboxes configured in the header
Resolved in Pega Version 8.1.9
After configuring multiple checkboxes where each checkbox had a different property and different DT as action set and then using them as a single column header in the table, the on-change of any one checkbox caused all of the checkboxes to be checked or unchecked in the column header. This was caused by the pega.ui.grid.prototype.checkAllIfInHeader, which selects or unselects all checkboxes present in table (header +. body) based on checkbox status in header. However, the header row should not be part of the iterator during this function, and the necessary update has been made.

Resolved "maximum limit for pending changes" error
Resolved in Pega Version 8.1.9
When attempting to create a work object in a custom way using doCreateNewCase from the Smart investigate layer by using the RMButtonWithoughtWorkCaseNGP section, a popup showed the error “You have reached maximum limit for pending changes. Please commit/cancel one or more changes to continue.” The error did not occur when creating the case using the out-of-the-box Create New Work action. This was traced to the custom configuration creating work object threads that were not destroyed after the work item is closed. To resolve this, handling has been updated for passing dynamiccontainerID and contentID parameters for OpenWorkByURL case. Note that the pzUpdateActionInfo activity must be called in any custom activity before the actual activity is invoked.
