[ODE] -- dAreConnected, doesn't work with Contacts ??

[HanSolo]

Hi, i am trying to detect when 1 body touchs other body(out of 
nearCallback), for example, 1 box falls over other box but the 
"dAreConnected" function ever returns 0
, if i attach the 2 boxes with 1 joint it works (other dJoint "Type", 
not "contact" type) but it seems that with dJointTypeContacts doesn't work.
(That function can be helpfull for me.)

¿¿ Why ??

Thanks (again) and sorry for my poor english.
