.NET getView() doesn't get the newest data after using Store add

I use client.Store(StoreMode.Add, …) to add new data, and use getView() to view the data. But getView() doesn’t give me the updated data immediately. On the 2nd time I call getView() it returns me the updated data.

when getting data via View set Stale(StaleMode.False) to update View before getting data.

I also set Stale(StaleMode.False) but sometime(everyday) return null value.
