解决Gxt ComboBox控件设置值有关问题

问题代码：

?

//初始化数据源
ListStore <ComBoModel> store = new ListStore <ComBoModel> ();
store.add (new ComBoModel ("Android", "0"));
store.add (new ComBoModel ("Smart","1"));
store.add (new ComBoModel ("Google","2"));
//初始化Combobox
ComboBox <ComBoModel> combobox = new ComboBox <ComBoModel> ();
combobox.setDisplayField ("name");
combobox.setValueField ("value");
combobox.setStore (store);


//在另外一个方法中设置value值
 combobox.setValue (new ComBoModel ("Smart","1") );
