I have noticed that ExtJs 4.x docs do not show single quotes around events in the listeners.
In ExtJs 3.x some examples show this and some do not.
We found that our results were more consistent in ExtJs 3.x when we single-quoted the listener events.
That said, is there an impact in ExtJs 4.x for using single quotes on the listener events?
Has this been fixed in ExtJs 4.x?
