Form input using Redux Form not updating

If you are using immutable data structures, instead of:

import { reduxForm } from 'redux-form';

use this:

import { reduxForm } from 'redux-form/immutable';

See here for more info http://redux-form.com/6.7.0/examples/immutable/

I was having the same problem and my mistake was very simple.

Here's what I had:

import { combineReducers } from 'redux';
import { reducer as forms } from 'redux-form';

import otherReducer from './otherReducer';

export default combineReducers({ otherReducer, forms });

Notice that I was importing redux-form reducer as forms and passing it as is to my combineReducers (like I did with otherReducer) using ES6 Object property value shorthand.

The problem is that the key used to pass redux-form reducer to our combineReducers MUST be named form, so we have to change it to:

export default combineReducers({ customer, form: forms });

or

import { reducer as form } from 'redux-form';
export default combineReducers({ otherReducer, form });

Hope this helps someone else...
