Hi everybody!

I’d appreciate your experience on Ember Data behavior (1.0.0-beta.15) in the following case:

In the Application route a dictionary is requested from server using `DS.Store.find('myDictionary')`

Later a user moves between routes and when that dictionary is required, the `DS.Store.all('myDictionary')` method is used to read data from Ember Data cache not requesting a server.

Let’s say the Ember app stays open for multiple days and in some moment Ember Data cache expires. What would happen if `DS.Store.all('myDictionary')` gets called afterwards?

Thank you!
