State is undefined, can not get initial state

Hi guys,

i'm trying implement redux immutable in my project but i got stuck at connect mapStateToProps because the state returned from redux is Map object from ImmutableJS and i can not access user property also other properties in state by `state.user` or `state.get('user')` . So i posted my code here and need some advice from you guys, thanks in advance! Here is my code:

**folder: store/configureStore.js**

```

"use strict";

import {applyMiddleware, createStore} from 'redux';
import thunk from 'redux-thunk';
var promise = require('./promise');
var array = require('./array');
import rootReducers from '../reducers';
var createLogger = require('redux-logger');
var {AsyncStorage} = require('react-native');
import Immutable from 'immutable';

var isDebuggingInChrome = __DEV__ && !!window.navigator.userAgent;
const initialState = Immutable.Map({
user: {
isLoggedIn: false,
username: null,
session_id: null,
name: null,
uid: null
}
});

var logger = createLogger({
predicate: (getState, action) => isDebuggingInChrome,
collapsed: true,
duration: true,
});

var createCassiStore = applyMiddleware(thunk, promise, array, logger)(createStore)

function configureStore(onComplete: ?()=> void) {
const store = createCassiStore(rootReducers, initialState);
if (isDebuggingInChrome) {
window.store = store;
}
return store;
}

module.exports = configureStore;
```

**folder: reduders/user.js**

```
'use strict'

import { createReducer } from 'redux-immutablejs'
import { fromJS } from 'immutable'

const initialState = fromJS({
isLoggedIn: false,
name: null,
session_id: null,
email: null,
uid: null,
})

const user = createReducer(initialState, {
'LOGGED_IN': (state, action) => state.merge({
user: {
isLoggedIn: true,
...action.data
}
})
});

module.exports = user

```

**folder reducers/index.js**

```
'use strict'

import {combineReducers} from 'redux-immutablejs';
import {reducer as formReducer} from 'redux-form/immutable';
import {userReducer} from './user';

export default combineReducers({
form: formReducer,
user: userReducer
});

```

**folder components/MyNavigator.js**

```
import { connect } from 'react-redux';
import React from 'react';
class MyNavigator extends React.Component {
render() {
return (

);
}

renderScene(route, navigator) {
if(route.signup)
return
if(route.home)
return
return
}
}
const mapStateToProps = state => {
return {
isLoggedIn: state.user.isLoggedIn || false // error here cannot get user of undefined
}
}

module.exports = connect(mapStateToProps)(MyNavigator);

```
