Question

这里是mycode：可能有一些错误，但我做得对，我认为我的问题是在Java代码中请你点亮，我试图渲染无线电值。

<p:selectOneRadio id="firstBill" value="#{myClass.myfee}" label="what to do?">
                        <f:verbatim>
                        <f:selectItems value="#{myClass.listMyFee}"/>
                        </f:verbatim>
                        </p:selectOneRadio>



@Name("myClass")
public class MyClass
{
private String fee;
 private Map<String, String> listMyFee;
public Myclass(){
//constructor
listMyFee = new LinkedHashMap<String, String>();
   listMyFee;.put("Yes", "Yes");
   listMyFee;.put("No", "No");

}

 public Map<String, String> getListMyFee()
  {
    return this.listMyFee;
  }


get and set for fee are written

您的bean代码错误，您需要f:selectItems List<SelectItem>列表。

看起来像这样：

List<SelectItem> list = new LinkedList<SelectItem>();
list.add(new SelectItem(<returnValue>, <displayValue>));

在你的xhtml文件中：

    <p:selectOneRadio id="firstBill" value="#{myClass.myfee}" label="what to do?">
          <f:selectItems value="#{myClass.list}" />
    </p:selectOneRadio>

primefaces不呈现f：selecteditems
