一个panelGrid的内部多的JSF组件(Multiple JSF components insi

我试图让使用Facelet标记文件，@ Balusc以前的答案在panelGrid的内部JSF 1.2组件的可重复使用的组如何使JSF复合元件的网格？作为参考。我抄/WEB-INF/tags/input.xhtml和example.taglib.xml和主要应用XHTML。但是，我遇到了一些问题。
1.如果我没有通过ID和简单做

<my:input id="cat" type="text" label="FirstName" bean="#{bean}" property="fName" required="true" />
<my:input id="dog" type="text" label="LastName" bean="#{bean}" property="lName" required="true />

在我的主要XHTML和打开该网页，我得到java.lang.IllegalArgumentException异常和异常跟踪：

2.To闯过这一点，当我在我的代码传递的id值

<my:input id="cat" type="text" label="FirstName" bean="#{bean}" property="fName" required="true" />
<my:input id="dog" type="text" label="LastName" bean="#{bean}" property="lName" required="true />

我得到重复的ID为组件j_id2：猫错误。

3.To突破这个，我删除了所有的C：当，只是不停地在input.xhtml“文本”的一个输入类型，现在我看到2个文本框的渲染，但是当我做的查看源代码，我看

<tr>
  <td>
    <c:set var="id" value="cat"></c:set>
    <c:set var="required" value="true"></c:set>
  </td>
  <td><label for="j_id2:cat">First Name: &nbsp;*&nbsp;</label></td>
  <td><input id="j_id2:cat" type="text" name="j_id2:cat" value="Smith" /></td>
</tr>
<tr>
  <td></td>
  <td>
    <c:set var="id" value="dog"></c:set>
    <c:set var="required" value="true"></c:set>
  </td>
  <td><label for="j_id2:dog">Last Name: &nbsp;*&nbsp;</label></td>
</tr>
<tr>
   <td><input id="j_id2:dog" type="text" name="j_id2:dog" value="Joe" /></td>
   <td></td>
</tr>

我期待2行，但看到3行instead.Also我没;吨希望C：在标签文件集定义是我的TD图的一部分。

任何指针将不胜感激。

对于Facelets的1.x中，你需要声明JSTL核心标签库中的以下XML命名空间：
