You mean this?
[quote:20c03klg]Source: Record Set
Recordset: Contacts (contact)
Related field(s): Last Name, First Name
Crits callback: CRM_ContactsCommon::contact_format_no_company[/quote:20c03klg]
So it's a proper one, however you've pointed something interesting to me...
It's like you should see your new field in admin panel, but you have to make additional changes in database to get it working.
Now I see that RB admin panel doesn't allow to fully change some parts of field definition. It won't allow you to set crits callback and it doesn't display it properly... too late for the fixed package. Fortunately it's a minor issue.
Please have a look at the database table crm_meeting_field. Param field of Employees field is a bit longer.
Add a field to contact from a admin panel, then navigate to contact_field, and adjust param field like in the meetings field table.
Unless you're going to remove meetings module you can safely use Meetings crits callback in contacts.
