title: Ext associations
body: <p>I have a question: The “associations” feature (HasMany-belongsTo) of ExtJs library is applicable only in nested JSON data? Is it doable to define two different stores with two different data retrieving “urls” (and two different models with the association definition?) and the “hasMany” works? Or, I have to define only one store (with one data retrieving “url” and a JSON output that is nested and reflects the data associations of the database) and then with the help of models “format” the data in a way that Ext can consume?
  If the second case it is true, how someone could handle large volume data (let’s say a blog: users=>blog-post=>blog-reply) using the Ext “association” feature?
  Sorry for my abstract writing style,
