I'm not sure your __bobo_traverse__ is doing what it should :-S

Because I don't think __bobo_traverse__ works as you expect, but I can't 
remember off the top of my head how it does work. Have a look at REQUEST.steps 
to see what names you have traversed and check your session data manager is 
being covered.

might be simpler... Have a look at the PathHandler product to see how 
__bobo_traverse__ hooks actually work and see if you can make it fit your model...
