MyFaces is acusing duplicate id that isn't duplicated

Question

I have an strange problem happening in my web application after I changed Mojarra to MyFaces... I have a xhtml file that is loaded from outside, in other words, this xhtml is reused a lot:

<ui:composition template="../templates/popup.xhtml">
<ui:param name="titulo" value="#{modeloPopup.rotulo}"/>
<ui:param name="popup" value="#{modeloPopup}"/>
<ui:param name="controladorPopup" value="#{controladorPopup}"/>
<ui:define name="conteudo">
    <h:panelGroup id="painelPopup" layout="block" styleClass="hrgi-div-form clearfix" style="width: 400px">
        <p:focus for="inputValor"/>
        <h:panelGroup layout="block" styleClass="clearfix" style="margin-bottom: 5px;">
            <p:fieldset styleClass="fieldset-novo-registro" legend="#{msgGerais['gerais.novo_registro']}">
                <h:outputLabel for="inputValor" value="#{modeloPopup.tituloNome}" styleClass="hrgi-label-form"/>
                <p:inputText id="inputValor" value="#{modeloPopup.elemento.valor}" maxlength="50" style="width: 210px"/>
            </p:fieldset>
            <p:commandButton value="#{msgGerais['gerais.adicionar']}" action="#{controladorPopup.adicionarValor}"
                             update="painelPopup alerta" style="margin-top: 10px;"/>
        </h:panelGroup>
        <h:panelGroup id="painelLista" binding="#{bindingPainel}" layout="block" styleClass="clearfix">
            <p:dataTable id="lista" var="bean" value="#{modeloPopup.lista}" scrollable="#{modeloPopup.lista.size()>5}"
                         height="145" rowEditListener="#{controladorPopup.editarValor}" onRowEditUpdate="alerta">
                <p:column headerText="Nome" sortBy="#{bean.valor}" style="width:80%">
                    <p:cellEditor>
                        <f:facet name="output">
                            <h:outputText value="#{bean.valor}"/>
                        </f:facet>
                        <f:facet name="input">
                            <p:inputText value="#{bean.valor}"/>
                        </f:facet>
                    </p:cellEditor>
                </p:column>
                <p:column headerText="#{msgGerais['gerais.acoes']}" style="width:20%">
                    <p:rowEditor/>
                    <p:commandLink action="#{controladorPopup.removerValor(bean)}"
                                   style="text-align: center;margin: auto;"
                                   update="#{bindingPainel.clientId} alerta confirmacao" immediate="true">
                        <h:graphicImage library="img" name="remover.png"/>
                    </p:commandLink>
                </p:column>
            </p:dataTable>
        </h:panelGroup>
    </h:panelGroup>
</ui:define>
</ui:composition>

this xhtml is used this way:

<h:form id="cadastroRamoAtividade">
<ui:include src="resources/components/popups/modulo_cadastro/popupCadastroString.xhtml">
    <ui:param name="modeloPopup" value="#{modeloPopupCadastroRamoAtividade}"/>
    <ui:param name="controladorPopup" value="#{controladorPopupCadastroRamoAtividade}"/>
    <ui:param name="idPopup" value="popupNovoCadastroRamoAtividade"/>
    <ui:param name="bindingPainel" value="#{painelListaRamoAtividade}"/>
</ui:include>
</h:form>

I'm receiving this error:

I've looked at html source at chrome and didn't found any repeated id... Someone knows how can I solve it??

I *guess* that `` is the root cause of this problem. Try removing that `binding` attribute and retry. — BalusC, Apr 26 '12 at 14:38
Solved, but now I'm using complete id in all my f:ajax tags, cause of [this](http://stackoverflow.com/questions/7666631/jsf-fajax-cannot-locate-component-on-context). Please @BalusC, create a answer for me mark as solved... — brevleq, Apr 27 '12 at 14:34

I guess that <h:panelGroup binding="#{bindingPainel}"> is the root cause of this problem. If you have multiple components with the same binding in the same view, then you will get this exception. The binding attribute must point to an unique and request based variable.

sorry i have to ask.. *multiple components with the same binding* are you refering to elements inside the panelGroup? (e.g. added via bindingPanel.getChildren.add(something)) – salgmachine Mar 12 '14 at 20:28
