Hmm, ok. This fix doesn't even solve your original problem - as it's
not taking into account whether the key was submitted - only whether
$constraint->in() contains values.

I also recall sri saying he wanted the implicit In constraint on
Select elements to be scrapped - too much magic.
That at least would fix your problem - though it would break backwards
compatability for people relying on that constraint being silently

I'm going to leave this until tomorrow, and hope sri's reading this
and makes a call.
I think the 2 choices are:
remove the implicit In constraint, but add an accessor to keep the
current behaviour,
add an accessor to override current behaviour by not adding the
constraint (which was Adam's original suggestion!).

Any opinions / other ideas?
