Dynamically generated id in tomahwak dataList (JSF 1.2) - jsf-1.2

Question

I cannot figure out how to generate dynamically id for elements in <t:dataList> which is inside <t:dataTable>. Code looks more or less like this :
<t:dataTable value="#{SomeBean.foo}" var="item">
<h:column rendered="true">
<div id="divpvmu">
<t:dataList value="#{item.templates}" var="template" rowCountVar="templateIndex">
<div id="saveBtn">
</div>
</t:dataList>
</div>
</h:column>
Obiously this code generate some number of divs with the same id="saveBtn"
. I would like to have distinct id for every generated div. I was trying to do this by this change :
<div id="saveBtn_#{templateIndex}">
, however then I'm getting an exception
javax.servlet.jsp.JspException: java.io.IOException: Example.jsp(50,31) JBWEB004178: #{..} is not allowed in template text
Is there any way to generate distinct id's for such a construction ? I'm using JSF 1.2.

There is the <t:div> tag. It allows you to use EL expression in id attribute.
So something like this should do the job:
<t:div id="saveBtn_#{templateIndex}" forceId="true">
JSF should also automatically generate id for you:
<t:dataList id="myList" value="#{item.templates}" var="template">
<t:div id="saveBtn">
</t:div>
</t:dataList>
This tag in t:dataTable, t:dataList and so on will generate id like:
myList:0:saveBtn for first element,
myList:1:saveBtn for second element, and so on.
