To be honest I do not know how to regenerate the binidings, I will look into
that.
ollowing your email, I went on and took the unit test code and created a
client. Given that this code works I am guessing that the thrift bindings
are in place and it is more that the client code does not support the new
functions yet.
I might be off track and don't know if there it is appropriate for someone
as new to this as I am to make changes to the client and submit them
(especially if some one else is already doing that). I could do that, if it
helped the group.
