TypeError: Cannot read property 'stopWatching' of undefined

[wighawag]

Here is a nodejs script that i execute via node script.js

var Web3 = require('web3');
var web3 = new Web3(); 

var EtherSim = require('ethersim'); 
var sim = new EtherSim.init();
web3.setProvider(sim.provider);

//getting bytecode and ABI...

sim.reset();
sim.createAccounts(10, function() {
    sim.setBalance(web3.eth.accounts[0], 123450000, function() {
        web3.eth.getAccounts(function(err, accs) {
            var TestContract = web3.eth.contract(ABI);
            TestContract.new({
                from: web3.eth.accounts[0],
                gas : 3000000,
                data: bytecode
            }, function(err, deployedContract){
                console.log(deployedContract);
                //sim.mine() //should be required to get address?
                var transactionReceipt = web3.eth.getTransactionReceipt(deployedContract.transactionHash);

                console.log(transactionReceipt.contractAddress);
                //sim.reset(); never ends
            });
        });
    }); 
});

I get the following error :

/vagrant/node_modules/web3/lib/web3/contract.js:128
                            filter.stopWatching();
                                  ^

if I uncomment the last sim.reset() node hang

any idea?

Looking at the code it seems a bit wierd that the callback given to Contract creation can be called multiple times (this is web3).
But the problem is not really that. The problem is that after the callback is performed there is this function:
checkForContractAddress
that expect contract._eth.filter to be defined (as a function) but it is undefined

This function is in web3 but maybe ethersim should make sure such filter function is defined?
