I am trying out enyo Sample Flickr App given in the docs. The function enyo.store.addSources to add the new data source is undefined in the latest build. I checked the JS Fiddle for the sample flickr app for the latest nightly build and it is also crashing because of the same reason.
Attached is a screen shot of the Chrome's console.
