ZK框架Listbox如何显示数据啊

listitem标签改成这样试下，<listitem value="${each }">

估计这里也只有你懂ZK了。网上查啊查，现在效果是：我再贴下最新的代码

你那个Controller注解没用的，去掉吧。  我贴下我的代码，你参考下，
首先我的Controller继承了SelectorComposer 跟你那个是否有区别我不太确定，老早的东西了，忘记了。
@Wire private Listbox adspList;
@Wire private Paging pager;
@Wire
private Datebox syncDateBox;我是这样注入页面元素的，变量名就是页面的id, 这个id我看到你后来也加上上去了。我不知道你不加@Wire注解能不能跟页面元素对应上，这个你确认下。
Pagination<Adspace> page = adspaceService.getOnePage(adSpc, curr);
        ListModelList<Adspace> model = new ListModelList<Adspace>(page.getResult());
        model.setMultiple(true);
        adspList.setModel(model);这里代码很清楚， serviec查询一页数据，跟你的基本一样。页面：<listbox id="adspList" check="true">
<listhead>
<listheader label="id" />
<listheader label="编号" sort="auto" />
</listhead>
<template name="model">
<listitem value="${each }">
<listcell label="${each.id }"></listcell>
<listcell label="${each.adZoneId }"></listcell>
</listitem>
</template>
</listbox>
        <paging id="pager" activePage="0" />跟你不太一样，你可以参考改下，看是否有用
这是

OK 非常感谢，对了还有个问题。我设置了 check="true"
我想实现批量选中删除，我后台如何获取到选中行呢？

Listbox 有个getSelectedItems方法，返回选中Listitem的集合，如何没有勾选则集合为空
