Cisco Firewall :: Object To Twice NAT Configuration ASA5505 8.4?

We have an ASA5505 that we need to enable hairpinning on.... In the old firmware versions, we used to be able to configure a public to private static mapping along with hairpinning by using
 
static (inside,outside) outside_ip inside_ip netmask 255.255.255.255
static (inside,inside) outside_ip inside_ip netmask 255.255.255.255
 
In 8.4, if I use object nat, the hairpin functionality works perfectly,
 
object network obj-insideip
  nat (inside,inside) static publicip
 
however, since object nat only allows a single nat statement, I was attempting to use a twice nat to enable the hairpin functionality, but have been unsuccessful in coming up with the right combination of parameters for the functionality.
 
nat (inside,inside) source static private_object public_object destination static public_object private_object
 
allows hairpinning to successully work from the same machine.  Meaning on any given host, I can ping itself using the private or public ip, but I can't get the right combination for hairpinning from any private host to another private host via the public ip.  Other combinations have yielded icmp responses, however, they specify the private IP as the source of the reply instead of the public ip.
