How are you setting 'user_type' ?

If it's in a config file, such as:
    - type: UserSelect
      name: foo
      user_type: bar

then internally, HTML-FormFu is essentially doing:
    my $elem = $form->element({
        type => 'UserSelect',
        name => 'foo',
    });
    $elem->user_type('bar');

which is why 'user_type' isn't yet set in _populate_options(), when
it's called by new().

I'd probably do it during process() instead:

sub process {
    my $self = shift;

    $self->_populate_options
        if !@{ $self->options };

    $self->next::method( @_ );
}
