Unable to attach <a4j:ajax> to non-ClientBehaviorHolder parent (richfaces column)

[rcordoba]

Hi,

   I´m getting this error: "Unable to attach <a4j:ajax> to non-ClientBehaviorHolder parent" when I try to add a4j:ajax when onclick in a datatable column.

Actually, if I do next, it doesn´t work:

<rich:column styleClass="columna" id="paisColumna" label="#{msj.pais}"  >

          <a4j:ajax event="change" listener="#{I18nBean.setPais}" status="esperaStatus" render="panelBuscarCharter" />

</rich:column>

Bean:

public void setPais(AjaxBehaviorEvent event) {

                    locale = new Locale("en");

                    FacesContext.getCurrentInstance().getViewRoot().setLocale(locale);

}

but if I do this (put the ajax call inside selectBooleanCheckBox in example, it works (with the same bean)  :

<rich:column styleClass="columna" id="paisColumna" label="#{msj.pais}"  >

                                                                      <h:selectBooleanCheckbox id="mismoPuerto3" value="#{InicioBean.mismoPuerto}" class="perrisCheckbox">

                                                                                <a4j:ajax event="change" listener="#{I18nBean.setPais}" status="esperaStatus" render="panelBuscarCharter" />

                                                                      </h:selectBooleanCheckbox>

                                                    </rich:column>

I guess it is because rich:column doesn´t implement ClientBehaviourHolder interface. But then, how can I achieve this?

I hope you can help me.

Thanks in advance,

Roberto.

Hi,

what exactly are you trying to do? From what I can see the column in question is empty (and there needs to be something the a4j:ajax could attach to), so what are you expecting to "change"?

Can you show us the whole table and say what is it supposed to be doing?

Hi Michal,

   thanks for your response.

Actually, I made so many changes that finally I copied the bas example. What I want to do is the common functionality to support internationalization. I mean, when the user click on a language link, a popupPanel with a datatable of countries will be opened. The user will be able to click on a row (with a country). It´s suppose that an ajax action will be executed, so the language will change to the selected one by the user.

I have read in another post that ajax click event in a rich:column is not working in richfaces 4. According to Ilya sugggestion, I have implemented with a "workaround" with jsFunction.

Please find attached my complete popupPanel code:

<rich:popupPanel id="popupPanelI18n" resizeable="false">

     <f:facet name="controls">

            <h:outputLink value="#" onclick="#{rich:component('popupPanelI18n')}.hide(); return false;">

                 <h:graphicImage value="/images/close.png" style="cursor:pointer" styleClass="hidelink" id="hideLinkPopupPanelI18n" />

            </h:outputLink>                   

     </f:facet>

     <a4j:jsFunction name="selectRow" action="#{I18nBean.setPais}" render="panelBuscarCharter" oncomplete="#{rich:component('popupPanelI18n')}.hide(); return false;">

            <a4j:param name="currentRow" assignTo="#{I18nBean.sLocale}"/>

     </a4j:jsFunction>

<div id="divI18n">

     <h:outputText value="#{msj.pais}" />

          <rich:dataTable id="PaisesTabla" value="#{I18nBean.internacionalizaciones}" var="i18n" onrowclick="selectRow('#{i18n.locale}');">

               <f:facet name="header">

                    <h:outputText value="#{msj.pais}"/>

               </f:facet>

               <rich:column styleClass="columna" id="banderaColumna" label="#{msj.bandera}" >

                    <h:graphicImage value="/images/banderas/#{i18n.locale}.png" id="bandera" styleClass="imagenPequena" />

                </rich:column>

                <rich:column styleClass="columna" id="paisColumna" label="#{msj.pais}">

                     <h:outputText value="#{i18n.pais}" />

                 </rich:column>

           </rich:dataTable>

</div>

</rich:popupPanel>

This is working.

Is this a correct approach?

Thanks,

Roberto.
