[Zope-dev] Zope 2.2.0b1 not authorized

I have a ZSQL method embedded into another ZSQL method and when I execute it I become the following error: “Error, Unauthorized: You are not authorized to access SQL.” If I execute the embedded ZSQL method alone I become no errors. The two methods have the same ownership. After searching in the mailing list I have seen a few people with the same problem but none of them have resolved it. Anyone knows the solution?
