Root Cause
A software use or operation error.
DataTable ListEditor used Internet Explorer 5 compatibility (quirks mode) support for backward compatibility. Few JavaScript APIs (Pega7 standard) do not work as expected in the Internet Explorer 5 compatibility mode. As a result, script errors occur in IE only. For more information, refer to the article for End of Support of Internet Explorer quirks mode: https://community.pega.com/knowledgebase/release-note/end-support-microsoft-internet-explorer-8-and-quirks-mode-applications
