我正在创建一个Icefaces Datatable.First列有单选按钮。点击第一行的单选按钮，我可以编辑行。在单击另一行的单选按钮时，应执行另一个操作（但不能编辑）。我在数据表底部有一个命令按钮，用于保存数据。在下面找到相同的代码
------------------ XHTML ----------------------
<h1>IceFaces 3 </h1>
<h:form>
<ice:selectOneRadio id="myRadioId"
value="#{order.checked}" layout="spread"

这里的问题是我无法调用OrderBean.java的editSelectedRow（ValueChangeEvent evt）方法
答案 0 :(得分：0)
我认为您缺少的是onchange属性，请执行以下操作：
<ice:selectOneRadio id="myRadioId"
value="#{order.checked}" layout="spread"
valueChangeListener="#{orderBean.editSelectedRow}"
onchange="submit()">
<f:selectItem itemValue="" />
</ice:selectOneRadio>
希望能帮助。
