how to generate dynamic id of tag?

[kannattaa]

i have a list of commodities and want to generate id of <a:outputPanel> that corresponds to commodity.id . then i am going to rerender particular <a:outputPanel> with ajax, but not all of them.
but #{currentCommodity.id} doesn't occur in result id :
source:

<a:repeat value="#{listCommodities.getCommodities()}" var="currentCommodity">
 <a:outputPanel id="#{currentCommodity.id}spinbox">
 #{currentCommodity.id}
 </a:outputPanel>
 </a:repeat>

result html:

<span id="j_id2:0:spinbox">450</span>
<span id="j_id2:1:spinbox">451</span>
<span id="j_id2:2:spinbox">550</span>
<span id="j_id2:3:spinbox">601</span>
<span id="j_id2:4:spinbox">500</span>

You normally can't set the id with an el statement in JSF.

i've resolved the problem

using of <a4j:ajaxListener type="org.ajax4jsf.ajax.ForceRender" /> is a decision

another way is to use a4j:repeat from xmlns:a4j="http://richfaces.org/a4j"
