sure, it works like you said ... but it's not what I want.
by doing that, you create an action ... when you will call "print" it
will call the __str__ (__repr__ is better in that case), which will
call the callback of myobject.
In my preceding post, the action was called by the "()" trick at the
end of line


In fact, MyObject will handle a list of all "js call"
If i do :
  o.js.toto()
  o.js.toto().titi(12,13)

I'd like my MyObject contains a list like that ["toto()","toto().titi
(12,23)"]

another idea ?
