Check added to resolve Ajax Container instantiation error in log
Resolved in Pega Version 8.4
When using the Microsoft Internet Explorer or Edge browsers, manually launching a Service Intent and clicking the F5 refresh button properly refreshed the screen, but the PegaRULES log file contained the error "(DynamicContainerDataModel) Error occurred while instantiating tab for the thread index." This issue / exception was observed only when pzCustomDCTabHeader was configured (pyEnableCustomTabHeaders) and when there was a AjaxContainer configured in the document. Because the CustomTabHeader recreation (DynamicContainerDataModel.updateCustomTabHeader) should be skipped for AjaxContainer, as CustomTabHeader is applicable only to the top level DC document and not to the AjaxContainer document, a check has been added to resolve this issue.

When no active document is available on login, first document will be marked active
Resolved in Pega Version 8.4
After logging into the user portal, attempting to perform operations like (opening a case/work object, opening reports etc.) caused the browser request to spin or freeze. The only way to recover was to close and re-launch the browser window/session and re-login. This issue occurred when there was an active reportdefinition document before the browser/node crash in the tabless dynamic container(DC) portal. After recovery, the dynamic container did not recreate the report definition document but instead tried to activate the first document in the portal, which in this case was the default harness configured in the Dynamic Container. As it was not yet loaded, exceptions were thrown. To resolve this, when no active document is available, the first document will be marked as the active document.

Left panel content visible after window resize
Resolved in Pega Version 8.4
After maximizing or resizing the window, the left pane on Designer Studio or User Portal either did not show the left panel or did not show the panel separator and did not display any content after clicking on separator navigation icon. It was also not possible to expand the Explorers again. This has been corrected.

Ad hoc task time validation done on correct thread
Resolved in Pega Version 8.4
The validation on a time value was not working correctly when two cases of the same type were open at the same time. For every ad hoc task, there is some validation on the time property. After submitting a value in a second ad hoc task, the validation was triggered but used the property from the first ad hoc task and showed the error in the second ad hoc task tab. This was traced to the datepicker taking the reference from the previous MDC when it needs to take it from the active MDC. To correct this, the control_datepicker has been upadted to use pega.ctx.getElemById.

Pagination context switch handling updated for mouse scroll
Resolved in Pega Version 8.4
When using various tables in the DMG application that have the Pagination mode set to 'Progressive' and that contain hyperlinked elements on which an 'Open Work by Handle' action has been defined, clicking an element that was loaded progressively intermittently generated an alert with the message 'Empty work item handle'. Investigation showed that dragging the scroll bar to access the latest cases worked, but using the mouse to scroll and select replicated the issue immediately. This was caused by context not being properly switched to the current harness while scrolling due to missing context switch handlers. To resolve this, code changes have been made to set the correct context before sending the request.

XSS protection added to layout runtime java and whitelist validation available for host/XFHost
Resolved in Pega Version 8.4
In order to protect against XSS issues, filtering has been added to the RepeatDynamicIndex parameter value in layout runtime java. In addition, a validation for X-Forward-Host value has been added which will be read from a local configuration. This is in the form of a white list regex filter for the host/XFHost header to ensure the URL's actions cannot be redirected.

Added check for section refresh when files are attached offline
Resolved in Pega Version 8.4
After attaching files in offline mode, the files intermittently did not show up in the "recent attachments" list when performing any action on the attachments section. This was traced to the asynchronous reload of sections, and has been resolved by adding a condition in the sectionRefreshCallback() to check if the response matches with the correct reload element.

Tab layout group handling improved
Resolved in Pega Version 8.4
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.

Improved post-upgrade compatibility for custom tabbed screen flows
Resolved in Pega Version 8.4
After upgrade, a screen flow with a customized harness saved-as from a TabbedScreenFlow harness and configured with client side validation disabled was displaying a blank white screen if validations failed when moving from one tab to another tab. When a tabbed screen flow has errors the necessary script bundles should be added, but this configuration was created prior to the introduction of templated controls and non-templated controls don't need script files. Because the ‘doesStreamMatchInputProperties’ method sets ‘researchmode’ to true, the ‘doOnlyOnce’ method evaluated to false and script files related to templating controls were not getting appended. For greater backwards compatibility, 'mResearchMode’ will be set to ‘true’ to make stream processing light weight. In addition, the researchmode check will be removed when adding scripts.

Enhancement added to customize the clearing of error messages when performing modal actions
Resolved in Pega Version 8.4
Opening any modal dialog, for example adding a row in Table/Grid layout, cleared any existing validation error messages on UI screen. In order to make this behavior customizable, a flag has been introduced to control the clearing of error messages from primary pages on grid actions. Updates have been made in the ui_grid, ui_grid_dragdrop and ui_repeatlayout JS files to include this flag in activity parameters and the pzdoGridAction activity has been modified to consider the flag.
