I have just started looking at ember in order to use it for a rich client application with a rails backend. The two way data binding is very cool. I am slowly working out through ember-data.
In order to help with debugging, I was using the toStringExtension method in my model. Howver, it seems to me that the toStringExtension is caching the computed value of the function. I am not sure if this is the expected behavior or not.
