LWUIT List已更改ListModel(LWUIT List with changed ListModel)

 我在LWUIT有一个List 。 我的问题是这个。 当我在List其中一个元素中按FIRE键时，所选项目会更改属性，以便更改List模型，当我尝试继续向下移动List会失去焦点。 
 
 我尝试重新加载新模型，重新绘制Form ，重新绘制List ，但似乎没有任何工作。 当我改变模型时，我总是失去焦点。 
 
 我能做什么？ 

I have a List in LWUIT. My problem is this. When I press FIRE key in one of the elements of the List,the selected item changes an attribute so the model of the Listchange, and when I try to continue going down the Listlose the focus.
 
I try to reload the new model, to repaint the Form, to repaint the List, but nothing seems to work. I always lose focus when I change the model.
 
What can I do?
