Hi Andreas,

I was mentioning this problem here about one year ago, and Adam told me
that this was the correct behaviour as documented by Apple:

**
To be valid, the receiver must have a formatter capable of converting
the object to and from its textual representation.
**

I don't like this either, because if you intend to use string values,
you need a dummy formatter that just passes the value.  I couldn't
really believe Cocoa's behaviour was like this, but I don't have access
to a Cocoa machine, so I couldn't verify it.

Greetings,
Dirk
