I am trying to get the reusable group of jsf 1.2 components inside a panelgrid using Facelet tag file with @Balusc's previous answer at How to make a grid of JSF composite component? as a reference. I have copied /WEB-INF/tags/input.xhtml and example.taglib.xml and the main application xhtml. However, I am running into some issues.
1. If I don't pass the id and simply do
<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 />
in my main xhtml and open that page, I am getting java.lang.IllegalArgumentException and the exception trace:
java.lang.IllegalArgumentException

2.To get past this, when I pass the id value in my tag
<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 />
I get duplicate Id for a component j_id2:cat error.

3.To get past this, I removed all the c:when and just kept one input type of ' text' in the input.xhtml and now I see 2 textboxes rendered but when I do view source, I see
<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: * </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: * </label></td>
</tr>
<tr>
<td><input id="j_id2:dog" type="text" name="j_id2:dog" value="Joe" /></td>
<td></td>
</tr>
I was expecting 2 rows but seeing 3 rows instead.Also I wasn;t expecting c:set definition in the tag file to be a part of my td view.
Any pointers will be appreciated.
