ExtJs ArrayStore（重新加载还是重新启动？）有可能吗？

I have the following Extjs3 ArrayStore. Elsewhere I'm listening for a value and reloading the store w/ new data elsewhere in the page (the code below the store). I'm looking for a way to 'reset' or reinit the store to it's original data after the load..i.e the next time thru the listenerI have the following Extjs3 ArrayStore. Elsewhe
