Hello,

I’ve been trying for a few days to create a :delegated or :layered web  
service with no success. I am wondering if I’m just not using the  
proper URL for the scaffold generator to test with. Using the default  
method, everything works just fine. I wanted to avoid having a  
different controller for every call, but maybe that’s not a bad way to  
go anway.

I’m also looking for a simple way to map :expected parms to a model  
object. I tried to use :expects =\> [Person] but I can’t. I can  
do :expects[:string, :string], returns =\> [Person]

I did want to be able to group like service methods in a single  
controller if possible. If you know of a good layered example that  
has all the code, that would be great - also if you know what the  
scaffold :invoke url should look like for a delegated or layerd  
service - that may be the problem too.

Thank you
