Hi Roberto,

Try adding <a4j:outputPanel with id attribute.
if you like to reRender all the Combobox means do like below,

<a4j:outputPanel id="panelOutput"/>


   <h:panelGroup>
                                                            <h:outputLabel value="Descrizione Folder : " style="display: block;" />
                                                            <rich:comboBox id="descrizione_folder_dinamicoCITCO" value="#{pl_voce_manuale.COD_FOLDER}" selectFirstOnUpdate="false" defaultLabel="seleziona il folder" required="true" enableManualInput = "false" requiredMessage="Folder obbligatorio">
                                                          <f:selectItems value="#{pl_voce_manuale.elencoFolder}" />
                                                               </rich:comboBox>
                                                               <rich:message for="descrizione_folder_dinamicoCITCO" errorClass="errorMessage"/>
                                                     </h:panelGroup>

<h:panelGroup>
                                                            <h:outputLabel value="Descrizione Prodotto : " style="display: block;" />
<rich:comboBox id="prodotto_dinamicoCITCO" value="#{pl_voce_manuale.COD_PRODOTTO}" selectFirstOnUpdate="false" defaultLabel="seleziona il prodotto" enableManualInput = "false" required="true" requiredMessage="Descrizione Prodotto obbligatorio">-->
       <f:selectItems value="#{pl_voce_manuale.elencoProdotto}" />

</rich:comboBox>
                                                               <rich:message for="prodotto_dinamicoCITCO" errorClass="errorMessage" />
                                                     </h:panelGroup>

<h:panelGroup>
                                                                         <h:outputLabel value="Divisa : " style="display: block;" />
                                                                      <rich:comboBox id="divisa_dinamicoCITCO" value="#{pl_voce_manuale.COD_DIV}" selectFirstOnUpdate="false" defaultLabel="seleziona la divisa" required="false" enableManualInput = "false" requiredMessage="Divisa obbligatorio">
                                                                    <f:selectItems value="#{pl_voce_manuale.elencoDivisa}" />
                                                                         </rich:comboBox>
                                                                         <rich:message for="divisa_dinamicoCITCO" errorClass="errorMessage"/>
                                                               </h:panelGroup>

</a4j:outputPanel>

Add the in the
<a4j:support event="onchanged" reRender="outputPanelID"...
---It will referesh all the combobox.....

If you like to refresh only one combo box means just rerender only the first combobox id in the <a4j:support tags reRender attribute.

Thanks,
Siva
