a4j commandLink and in rich contextMenu

[nswbity]

I must move a4j:commandLink from rich:datatable to rich:menuItem in rich:contextMenu.

Here the current code:

                         <rich:contextMenu attached="false" id="menu" submitMode="ajax"

                                                                      oncollapse="row.style.backgroundColor='#{a4jSkin.tableBackgroundColor}'">

                                                                      <rich:menuItem ajaxSingle="true" rendered="true"

                                                                                submitMode="ajax">

                                                                                <a:commandLink

                                                                                          action="#{metadatiDocumentoController.visualizzaMetadati(idX)}"

                                                                                          status="waitingModalPanelStatus"

                                                                                          reRender="metadatiDocumentoPanel"

                                                                                          oncomplete="Richfaces.showModalPanel('metadatiDocumentoPanel')"

                                                                                          immediate="false">

                                                 <h:graphicImage value="/img/document-attribute-i.png"

                                                                                                    title="#{messages['label.azioni.metadati']}" />

                                                                                </a:commandLink>

                                                                      </rich:menuItem>

                                                            </rich:contextMenu>

                                                  <a:outputPanel id="listaDocumentiPanel">

                                                            <rich:dataTable id="listaDocumenti"

                                                                      rows="#{listaDocumentiController.documentiPerPagina}"

                                                                      value="#{listaDocumentiController.documenti}" var="documento"

                                                                      rowKeyVar="documentoKey"

                                                                      onRowMouseOver="jQuery(this).addClass('tableRowMouseOver');"

                                                                      onRowMouseOut="jQuery(this).removeClass('tableRowMouseOver');"

                                                                      rendered="#{listaDocumentiController.documenti.size()!=0}"

                                                                      onRowContextMenu="if (row) row.style.backgroundColor='#{a4jSkin.tableBackgroundColor}';

                this.style.backgroundColor='#F1F1F1'; row=this; idDoc='#{documento.id}';

                #{rich:component('menu')}.show(event,{id:'#{documento.id}', currentRow:'#{documentoKey}'});

                return false;">>

                                   ....

                                                                      <rich:column width="75px">

                                                                                <a:commandLink

                                                                                          action="#{metadatiDocumentoController.visualizzaMetadati(documento.id)}"

                                                                                          status="waitingModalPanelStatus"

                                                                                          reRender="metadatiDocumentoPanel"

                                                                                          oncomplete="Richfaces.showModalPanel('metadatiDocumentoPanel')">

                                                                                          <h:graphicImage value="/img/document-attribute-i.png"

                                                                                                    title="#{messages['label.azioni.metadati']}" />

                                                                                </a:commandLink>

                         ...

                                    <rich:componentControl event="oncontextmenu" for="menu"

                                                                                operation="show">

                                                                                <f:param value="#{documento.id}" name="idX" />

                                                                      </rich:componentControl>

                                                            </rich:dataTable>

                                                  </a:outputPanel>

                                        </h:form>

The commandLink action works fine in rich:datable instead in the rich:menuItem parameter idX is always resolved to string empty in my backing bean.

Do you have any suggestions??
