由於某種原因，ExtJS4網格的這種配置不會更新。當你點擊一個單元格時，改變一個值，它會觸發創建的URL，而不是代理中定義的更新URL，並在FF4中使用Firebug進行觀察。奇怪的是，datachanged事件在頁面啓動時加載存儲後觸發，但在數據實際更改後無法啓動。此外，網格將所有行發送到創建網址。ExtJS4網格不會更新遠程數據庫
誰能告訴我我做錯了什麼？

「因爲您的網格正在使用CellEdit mixin」因此，使用插件會導致對單個單元格進行更新以觸發代理上的create（而不是更新）並將所有行發送給它？這似乎是非常錯誤的。另外，問題並不在於服務器沒有任何內容，而是所有20行都被髮送到創建URL！ – alphadogg 2011-05-27 23:19:24
我現在只是將ExtJS 4下載到我的機器上，因爲我不確信這是答案......我的道歉，如果它不是 – JamesHalsall 2011-05-27 23:22:10
沒問題！你的時間是最感激。 – alphadogg 2011-05-27 23:22:34
