PS: ZnNeoClient has been renamed ZnClient since more than a month, you probably best use the latest version.Yes, I know. As I wrote I tested this with #13315 and there is only ZnNeoClient. I updated pharo two times and rolled back. Then I remember you call it "the client has been renamed" but my code those not work with ZnClient. It looks as it has less in common with ZnNeoClient. So I postpone upgrading day after day :)
