Hi Bastien,

Indeed, you're right. I didn't notice that my minimal test was using an old version of Org. Now, with a recent version of Org, my minimal test works well. Anyway, I still have this issue with my full setup... it should then come from somewhere else. I need some more time to locate the faulty spot. Thanks a lot for your help. Regards, Francesco
