Operation was rejected (seq but not src). Trying to rollback change locally.

[l-liava-l]

Hi everyone!

Trying to use ShareJs, but have a problem with submitOp.
Model change, but new value is not set in mongoDB.

I have a warning message:
"Operation was rejected (seq but not src). Trying to rollback change locally."

What am i doing wrong?

client:

        var socket = new BCSocket('http://localhost:8002/channel', {reconnect: true});
        var share = new sharejs.Connection(socket);

        var doc = share.get('lists', '1433606385077');

        doc.subscribe(function(){
            console.log('onChange:', doc.getSnapshot());
        });

        doc.whenReady(function(){
            console.log('onReady: ', doc.getSnapshot());
            doc.submitOp([{p:['title', 4], si: 'test'}]);
        });

server:

(function(){
    var Duplex = require('stream').Duplex;
    var browserChannel = require('browserchannel').server
    var backend = require('livedb').client(require('livedb-mongo')(dbUrl));
    var share = require('share').server.createClient({backend: backend});
    var bodyParser = require('body-parser');
    var core = require('express')();
    var server = createServer();
    var dbUrl = 'mongodb://localhost:27017/todoList'

    core.use(bodyParser.json());     
    core.use(bodyParser.urlencoded({
      extended: true
    })); 

    core.use(function(req, res, next) {
        var headers = {
            'Cache-Control' : 'max-age:120'  
        };

        if(req.headers.origin){         
            res.setHeader('Access-Control-Allow-Origin', req.headers.origin);
            res.setHeader('Access-Control-Allow-Methods',  'GET, POST, OPTIONS');
            res.setHeader('Access-Control-Allow-Headers', 'Content-Type, X-Requested-With, X-PINGOTHER');
            res.setHeader('Access-Control-Max-Age', 86400);
        }

        next();
    });

    var mongodb = require('mongodb').connect(dbUrl, function(err, db){
        var usersAPI = new require('./api/users')(core, db);
        var listsAPI = new require('./api/lists')(core, db, backend);

        core.use(browserChannel({webserver: server}, function(client){
            console.log('New session: ' + client.id +' from ' + client.address);
            var stream = new Duplex({objectMode: true});

            listsAPI(client);

            stream._read = function() {};
            stream._write = function(chunk, encoding, callback) {

            if(client.state !== 'closed') {
                client.send(chunk);
            }
                callback();
            };

            client.on('message', function(data) {
                stream.push(data);
            });

            client.on('close', function(reason) {
                stream.push(null);
            });

            stream.on('end', function() {
                client.close();
            });

            return share.listen(stream);
        }));
    }); 

    function createServer(){
        return core.listen(8002, function () {
            var host = server.address().address;
            var port = server.address().port;
            console.log('Server started on', host + ':' + port);
        });
    }
})();

i found this error came from the npm version, but if you are using the master branch everything work great!

[mschrepel]

I just removed my npm module and installed the master branch and started getting the same error. It works fine with 0.7.3, then fails with master branch and the most recent npm package.

[pedrosanta]

Take notice that the builtin lib on /dist folder on npm package is outdated/has issues (#378, #382), but from what @mschrepel said, he also tried with the master branch, so...

[typpo]

Same problem here. Specifying npm version 0.7.3 instead of the latest fixed it. The latest version does not have a text.js in the dist folder, whereas this one does.

[pedrosanta]

Try to update to the newly released 0.7.40 and see if it happens, since the /dist folder lib was fixed.
