在sencha touch中过滤2

Question

我正在使用Sencha Touch 2.使用store.filter时，所有te记录都会被过滤掉。

基本上我有一个主题列表。当我点击某个特定主题时，我想显示该特定主题的评论列表。我使用了2家商店。存储主题和topicID的一个。其他存储评论主题，评论，主题ID和评论ID。因此，当我披露特定主题时，我使用其topicID来过滤我的评论商店

//这是我的主要主题列表视图

    items: [{

                {
                    xtype: "button",
                    ui: "back",
                    action:'backButton',
