Malcom,

I put this bit of code in my multiply-inherited controllers to make sure everybody's create_action sub is called:

use Class::C3;
sub create_action {
    my $self = shift;

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

It works for me.  If somebody has a better way to get around the problem, I'd love to hear it.
