Ok, in this case. Unfortunately for me I used in fact the 
DistantPersistentSAPCollider wich is a bit different and with which the 
transition I speak about seems indeed to be possible... I never 
interested me enough about these Engines so I surely copied somewhere 
the lines to insert it in my simulations without understanding them. 
Unless being very very very lucky that's really not the way to deal with 
YADE...
