[html-formfu] Unable to create a Callback constraint via populate()

Hi Carl!

Me again. ;-)

As arleady noted, this works perfectly for single elements. However, I
now discovered that something like this:

my $empty_to_undef = sub {
    [...]
};

[...]
    element_defaults => {
        Text    => {
            transformers => [{
                type        => 'Callback',
                callback    => $empty_to_undef,
            }],
        }
    },
[...]

triggers the:

Can't store CODE items at /u/www/cheiron/cryo/Cryo/script/../lib/HTML/FormFu/ObjectUtil.pm line 108.

error as before. It seems that coderefs are accepted if I place constraints
or transformers or whatever inside single elements, but not if I place
them as element_defaults.

Thanks,
Michele.
