title: React Flux multiple store communication
body: <p>I'm facing a problem with Flux architecture in a React application. Here is what I have : </p>
  
  <ul>
  <li>Store A with objects that have two main fields : "name" and "id" </li>
  <li>Store B which has a dependency to objects' field "name" present in store A</li>
  <li>An API that I can't change which send the value "id" of a store A's object </li>
  <li>An action that is fetching informations from the API</li>
  </ul>
  
  <p>The problem is that the API sends me an information that store B needs to handle (thanks to the dispatcher) to update the "name" (field from store A).</p>
  
  <p>So : API sends me "id" but in my store B I need to have the "name". According to the Flux architecture I can't communicate directly from my Action to my Store A, so I can't call any function like "getNameById". The "id" field was only added on the application because of the information sent by the API.</p>
  
  <p>Without changing the API, how can I manage to have this "remapping" from "id" to "name" and where to put it ? I can't see where this has to be in a Flux architecture. </p>
  
  <p>Thanks ! </p>
