document is not defined when attempting to setState from the return of an async call in componentWillMount

Question

I grab my data in my componentWillMount call of my component [actually it\'s in a mixin, but same idea]. After the ajax call returns, I attempt to setState, but I get the error

Answer 1

Trying this out in a simple component, the following works just fine:

  getInitialState: function() {
    return {
      title: 'One'
    };
  },

  componentWillMount: function() {
    setTimeout(function(){
      this.setState({
        title: 'Two'
      });
    }.bind(this), 2000);
  },

Can you post the exact error, and perhaps the stacktrace, so we may better see the problem you are having?
