I get this error when I try to start up my ExtJS 4.2 app:

Uncaught TypeError: Cannot read property 'buffered' of undefined

I've double checked all my store ids and and names to ensure that they are all spelt correctly but I'm still having this issue :(. Is there anything else I could try to solve this error?

Thanks in advance.

I typically get this error when one of my grids is referencing a store that has not been defined in either the controller instantiating the view or app.js (depending on how the app is structured)

In my case, usign Sencha Architect 3.5, I had to drag to the Store Section the store and it works again. I didn't know when the Application loss the relation with the store but doing that it's working again.
