it seems have deserialization problem. stack says trying read unsigned short amf , can't stream has no more bytes read. (basically trying read more data amf contains) java classes , as3 classes not synchronised. did modify java classes , forgot regenerate as3 files granite plugin (or maven plugin)? adding field on java side without regenerating reason.

granite serialization system based on iexternalizable on as3 side: explicit (a huge difference blazeds can adapt data @ runtime , can convert type fields instance @ runtime).

check generation of as3 files , granite server configuration.
