我正在開發使用的PhoneGap和煎茶觸摸2安卓2.3.3應用...煎茶觸摸樹商店「對象有沒有方法getRootNode」
我從我重定向到嵌套列表視圖的登入查看我的應用程序......我用了一個在線商店的嵌套列表，而我所定義的類型爲「樹」的店......
的我第一次嘗試加載應用程序，當我點擊登錄它給我一個錯誤...錯誤如下所述：
Uncaught TypeError: Object [object Object] has no method 'getRootNode' at file:///android_asset/www/sencha/sencha-touch-all.js:15
但獲得如果我強迫錯誤關閉應用程序並打開它再次一切正常......
我的代碼是：

我需要儘快擺脫這個錯誤...我的應用程序中的一切從第二次開始工作正常...我認爲問題是與我定義的商店...請幫助我的傢伙.. 。 謝謝提前... !!!
所以你的存儲中定義的？ –
