For Home Page Widgets containing Incident report list content, selecting “Group By Priority” option from the context menu of Priority column, the list gets grouped by Priority.
Next , If we would like to "Group By State" and click on the context menu of State column , the option "Group By Priority" appears instead of "Group By State" on the context menu.
But if we click on "Group By Priority" option on context menu of State column , the list gets grouped by State, which is correct.
Kingston Patch 4
In Kingston Patch 5 instance , It works as expected.
i.e. Context menu on each column shows the option "Group by <Column_Name on which context menu is shown>"
Hence, to resolve the issue , upgrade to Kingston Patch 5 (No workaround available)
