I see, in the same way, we're assigning CustomLongTextField for the expression fields, we could do the same for ref fields, by default showing the Beans list. Maybe something like the following could help.

    case String:
      /* catalog preprocessor put 'string' as a type and the javaType as a schema $comment */
      if (comment?.startsWith('class:') || props.name.startsWith('ref')) {
        return BeanReferenceField;
