Hi,
The error states that Tapestry Plastic failed to build a proxy class for
the Session interface because it found duplicate method signature.
I saw this error once when I tried to implement generic support and had two
methods with same erasure types.
Maybe if you find the name of the method that fails -- it'd help? Try
attaching with debugger and lookup name of the method.
