    Thanks for the bug report. Looks like the problem is caused by the base class having the same name as the derived class (Session). The compiler should (but doesn't) emit a scoped name when it calls the base class constructor.

    As a work-around for the time being, the generated code should compile if you rename the derived class to something other than "Session".

    Cheers,

    Michi.
