Hi, You should use the users mailing group, since the intention of this group is to discuss the further development on mina itself.
Seems like you need different decoders for different messages, so try using a MessageDecoder. You can specify multiple MessageDecoders at a DemuxingProtocolDecoder, that iterates through the decodable methods of the MDs, until any of them says OK. Then decode is called at that MD.
