Andrew,
Thank you, that did it. I was thinking I had to change something on the server,
I now realize the 'on the wire' format is always the same, right? It's the
client that has to be instructed on how to deserialize.
But does it mean that If I have the EO Model also on the client it will
instantiate the right classes? I get this now :
ERROR er.extensions.eof.ERXEntityClassDescription - Entity Obra not found in
the default model group!
Also if I'm also using wonder, what's your advice? Better to subclass ERXApp
and only implement the bits need for JSONRPC?
Thank you again for sharing your work and answering questions.
Best regards,
Henrique
