Andreas, Eric,

  Thank you both for your help.

  Eric, I noticed the HTTP protocol didn't pass a response object when I 
used the Protocol.Save, but I did a small change to correct that :

    callUserCallback: function(resp, options) {
        var opt = options[resp.requestType];
        if(opt && opt.callback) {
            opt.callback.call(opt.scope, resp);
        }
        if(resp.last && options.callback) {
            options.callback.call(options.scope, resp); //<----- added resp
        }
    },

  That way, I could get the onCommit of the save strategy to have the 
response object.

  Anyway, I'll try what you proposed instead.  Thanks again.

Best regards,
