往WINDOWS里面添加表格。只有第一次打开的时侯能显示。

Question

var xxx=new com.wutai.gridpanel
items:[
{
layout : "column",
items : [{ columnWidth:.50,
layout:"form",
items:[getgoodsgrid,notloadgrid]
},{ columnWidth:.50,
layout:"form",
items:[loadinggrid,goodslist]
}
]
}
]
});

xxx.show();
xxx.items.items[0].items.items[0].remove(xxx.items.items[0].items.items[0].items.items[1]);
xxx.items.items[0].items.items[0].add(shortnotloadgrid);
xxx.items.items[0].items.items[0].doLayout();
为什么只能显示一次。关掉一掉。再打开添加的这个表格就不显示了。
[b]问题补充：[/b]
closeaction是HIDE
REMOVE是把那个表格去掉换上新的表格。

第一次显示。关了以后再开就不显示了。

第一那个EXT。GETCMP（“SHOWWIN”）是从哪来的。。。
第一个变量WIND的作用是什么。您的代码好像运行不了。

修改了一下.忘记你说的窗口关闭后再打开的问题了
