                                <h:selectBooleanCheckbox id="listCheckbox_#{i}" name="listCheckbox_#{i}"                                                                        
                                valueChangeListener="#{popupController.addUserListMember}" immediate="true">

                            </h:selectBooleanCheckbox>
                            </td>
                            <td valign="middle" align="left" class="alertSelect" width="145">
                                <div style="width: 170px; height: auto; word-wrap: break-word; white-space: pre-wrap;">
                                    <h:outputText style="padding-right: 8px;" value="#{listByUser.name}" />                                 
                                </div>                              
                            </td>
                        </tr>                                           
                    </a4j:repeat>                   
                </table>    
            </div>          
        </a4j:outputPanel>
    </a4j:form>

</ui:composition>

And the addUserListMember of PopupController is

public void addUserListMember(ValueChangeEvent event) throws Exception {
    System.out.println("=========================== PopupController.addUserListMember() ==================");
    Boolean isChecked = (Boolean) event.getNewValue();
    if(isChecked) {
        System.out.println("===== Checked =====");                                              
    } else {
        System.out.println("===== Un Checked =====");
    }                
}

But the valuechangelistner is not working. I can't use this.form.submit() because it will not fit into the code. I am in jsf 1.2.

What is the remedy? Thanks.


The valueChangeListener is not a client side event/happening. It's fully server side. You should really submit the form to the server side after you change the value in order to get it invoked.

As you're apparently already using Ajax4jsf, you could just add an <a4j:support>.

<h:selectBooleanCheckbox ...>
    <a4j:support event="onclick" reRender="someOtherComponentIfNecessary" />
</h:selectBooleanCheckbox>
