A store will not load its own records into its data member if events are suppressed.

The store uses the onDataRefresh event to trigger loading the records into data. It will properly return the records to the callback registered during the .load() call, but will not load them internally.

SDK Version 2.0.1.1

It happens in data/Store.js, on line 1901 in the onProxyLoad method. If the proxy was successful, it attempts to fire the 'datarefresh' event. It also sends a callback with that firing that should have been called after all the event handlers (Store.doDataRefresh). However, if you trace into the mixin/Observable class fireAction and then doFireEvent, we find that the method returns immediately if events are suppressed, not bothering to call the registered callback.
