I'm looking to convert a few custom fields from type "Contact Reference" to "Entity Reference".
However when I convert the fields, the autocomplete "advanced filter" stops working.
action=lookup&group=106
BEFORE
As a Contact Reference field, the advanced filter works fine and displays only the contacts in the specified contact group.
AFTER
When it becomes an Entity Reference field, the autocomplete displays ANY contact of any type, totally ignoring the filter.
I have tried playing with the advanced filter parameters but no luck. I don't see any relevant documentation.
Any ideas?
