There's also the controller attribute "Always Use Multi Value

Of course, this won't help if your textfield is editable and bound
to the controller's selection.foo keypath and the user tries to edit
the value.
Well, as said, in many cases I really need the compound value, in the
likely case that the property is the same for the whole selection.
However, for a complete library the compound value is useless. So I
might have to tweak this Multiple Value behavior.
The user will rarely have to edit values, it is mostly (though not
strictly) a consulting UI. If he does, it is no more than once per
object/property. In that case, I can take the overhead if necessary.
