[Newbie] Plone/workflow change ownership

[frederic.willem]

Hi all,

I would like to change the ownership of an object when changing its
state.
However when I call :
obj=state_change
print obj.getOwnerTuple()

I get (['MyPortal', 'portal_workflow', 'TC_Workflow'], 'scripts') with
scripts as owner.
The method changeOwnership do nothing.

Are there any tips to change the ownership during a state change?

Thanks in advance and have a pretty new year.
