How concat with JSF code in id attribute on XHTML?
<p>I am working with JSF 2.2 and I would like to build dynamic forms with jsf; this is my code:</p>

<pre><code>&lt;h:form id="myForm"&gt;
    &lt;ui:repeat value="#{bean.list}" var="object"&gt;
        &lt;h:panelGroup id="something#{object.id}"&gt;
            &lt;h:commandButton value="update" action="#{bean.doSomething}"&gt;
                &lt;f:ajax render="another#{object.id}" execute ="something#{object.id}"/&gt;
            &lt;/h:commandButton&gt;
        &lt;/h:panelGroup&gt;
        &lt;h:panelGroup id="another#{object.id}"&gt;
             &lt;!--....--&gt;
        &lt;/h:panelGroup&gt;
    &lt;/ui:repeat&gt;
&lt;/h:form&gt;
</code></pre>

<p>It not working. I checked html generated and <code>something#{object.id}</code> is represented as :myForm:j_idt93:0:something, without <code>object.id</code>. For this reason not working.</p>

<p>I  changed the <code>h:form</code> into <code>ui:repeat</code> and this solution working, but as I need update <code>another#{object.id}</code>, with <code>h:form</code> I can't point which <code>another</code>  update.</p>

<p>Thank you!</p>
