After upgrading from 14.1 to 17.2, the following variable does not work in table:
$({'variable': $("input[_id='txtf_fieldname']").attr('value')})
Release : 17.2
Component : SERVICE DESK MANAGER
The table plugin variable should be changed from
$({'variable': $("input[_id='txtf_fieldname']").attr('value')})
to
$({'variable': ca_fdGetTextFieldValue(ca_fd.formId,'txtf_fieldname')})
