        afterstart 这个事件是自己加的，因为如果在beforeedit事件中想对自己的控件初始化，那是不可能的，因为beforeedit时，roweditor控件还没有渲染，所以，我加了afterstart事件，该事件在roweditor显示后立即调用，所以，可以在这里进行初始化。
        要注意的是通过roweditor控件进行遍历来访问自定义的composite控件
        editor.items.items[0]，这里并不是我写重了，而是roweditor控件的items竟然不是一个集合，而是一个对象，在这里我也耗了一些时间，最后还是通过firebug输出editor对象发现的
        editor.items.items[0]就是compositefield组件，通过该组件的items集合，就可以以标准的形式访问其子组件，接下来，就可以初始化了
        因为最后一个combobox的数据是要通过前两个combobox级联选取后载入的，所以，在这里载入其数据进行初始化，但是注意，我是在callback中执行的，因为jsonstore的load动作是异步的，所以，必须通过callback事件的回调在数据载入成功后，再用setValue来初始化值

validateedit事件是在按了确认时执行的，用来验证roweditor中各控件的值，在这里，我执行了一个自定义的验证动作，因为我不想用户可以添加重复的物料，所以，我通过遍历jsonstore，将每条记录的物料值与用户选择的物料值进行比较，如果发现已经存在，则提示用户不要重复加入
