Please note, I wasn't suggesting that you use a custom type if you go
the "only override display" route.  You use the ShowComponentName
callback in Elements/ShowCustomFields to say "For these CFs, use
ShowCustomField_JSON_Encoded_Resource_Field" and then editing just
works as a normal text box.

Alternately, again, ensure your MaxValues is set properly for your
custom CF type.
