salut zmove
there is also something strange lini 616 : at the all end of the module i saw that the status is updated : i think it's a mistake because just before the hook for workflow-ng paiement event is called. Because of the status update at the end of the module (that is saying status="checkout" or something like that), workflow ng can't work correctly at this level : his order's status update is overriden by the end of the module...

It seems that this line is not useful and it confused me a long time, so i think it's better to disable it
