Symptoms
Reference field icons are not clickable and users get the error g_sc_form not defined.
Release
Jakarta , Kingston , London
Cause
This happened because the Variable editor was configured in two different form sections on the same form and work notes and activities formatters were also configured twice hence breaking the form.
Resolution
Once these fields were configured once per form section and duplication was removed it worked as expected.
