parsing an extension isn't working properly

[mwildehahn]

i have something like the following proto structure:

// file: soa.proto

message ActionResponse {
    optional bool success = 1 [default = false];
    extensions 100 to max;
}
message Response {
    repeated ActionResponse actions = 1;
}

in another file i register these extensions:

// file: response_registry.proto
message UserServiceResponses {
    extend soa.ActionResponse {
        optional actions.AuthenticateUser.Response authenticate_user = 101;
    }
}

to parse the message properly I had to muck with the compiler to make all of the extensionRegistry variables public and then do:

let response = Response.parseFromNSData(data!, extensionRegistry: ResponseRegistryRoot.sharedInstance.extensionRegistry)

i think the issue is that the extensionRegistry gets instantiated for each root object, so the extensionRegistry attached to Response doesn't have any knowledge of the extensions added within response_registry.proto file.

is there something I'm missing?

it seems like either the extensionRegistry should be public and you should be able to parse with whatever extensionRegistry you want, or you have a single extensionRegistry instance so you don't have this issue.

I saw there was a //TODO marked above extensionRegistry, so not sure if this is just something you haven't gotten to yet.
