Re: json-rpc Lists and arrays

[Luciano Resende <lu...@gmail.com>]

If I understood it correctly, I've seen some similar issues, and the
cause was that the Service Interface was not annotated as with
@Remote, thus the data binding framework wasn't really intercepting
the calls and doing the proper conversion to json. Could you please
check that ?
