Uncaught TypeError: Cannot read property 'dtTmHvr' of undefined

Steps to Reproduce

Run any ListView with a custom Filter section, which has dateTime control in it.

Root Cause

A defect in Pegasystems’ code or rules:
Whenever custom filter criteria is configured in list view, WorkFormStandard HTML fragment must be included as part of ListViewHeader for the user interface (UI) controls to work properly. But as part of BUG-148168, the code that includes WorkFormStandard has been commented. This caused the JS exception because some of the dependent JS files are not included in the HTML markup.


Apply HFix-29164.
