title: How to access nested models from store in ExtJs 4
body: <p>I just downloaded the final version of ExtJs 4 and I'm trying to implement some things using new Model approach. </p>
  
  <p>For instance I have a model named SetupModel, it has 2 nested models Users, Reports. 
  I create new store and I set the Model property of the store = SetupModel. </p>
  
  <p>The question is - how can I access my nested properties after data was loaded into the store?</p>
  
  <p>I need something like myStore.data.Users(), but is incorrect.</p>
  
  <p>Any thoughts?</p>
