ui:include - richPanelMenu - a4j - Lifecycle problem

[dragnic]

Hey dudes,

i researched a lot of articles and posts, but i actually dont get the solution that fits

i am using richfaces 4 with faclets.

i generated a menu with richPanelMenu.. but maybe the code is much more helpfull...

<div class='formContainer'>
     <div class='formMenu'>
        <h:form>
             <rich:panelMenu mode='ajax' groupMode='ajax'
              itemChangeListener="#{fgr.updateValue}">
             <c:forEach items='#{fgr.formItems}' var='formItem'>
                  <rich:panelMenuItem label='#{formItem.name}' name='#{formItem.template}' render='formContent' execute='@region'/>
             </c:forEach>
             </rich:panelMenu>
         </h:form>                
     </div><!--  .formMenu -->
     <div class='formContent'>
         <a4j:outputPanel id='formContent'>
             #{fgr.value}
             <ui:include src="#{fgr.value}" />
         </a4j:outputPanel>
     </div><!--  .formContent -->
</div><!--  .formContainer -->

and the bean i am using

import java.util.LinkedList;
import java.util.List;

import javax.annotation.PostConstruct;
import javax.faces.event.FacesEvent;
import javax.inject.Named;
import javax.inject.Singleton;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;

import ******.JsfResource;

import org.richfaces.event.ItemChangeEvent;

@Named
@Singleton
public class Fgr {

    static final Log      logger = LogFactory.getLog(Fgr.class);

    private List<FormItem> formItems;

    private String value;

    public Fgr() {}

    @PostConstruct
    private void postConstruct() {
        formItems = new LinkedList<FormItem>();
    }

    public List<FormItem> getFormItems() {
        if(formItems.size() <= 0) {
            formItems.add(new FormItem("fID1", JsfResource.getJsfResource("portalMain", "formsMenuNewPerson"),       "/views/forms/personForm.xhtml"));
            formItems.add(new FormItem("fID2", JsfResource.getJsfResource("portalMain", "formsMenuNewOrganisation"), "/views/forms/oragnisationForm.xhtml"));
            formItems.add(new FormItem("fID3", JsfResource.getJsfResource("portalMain", "formsMenuNewDevice"),       "/views/forms/deviceForm.xhtml"));
        }

        return formItems; 
    }

    public String getValue() { return value; }
    public void setValue(String value) { this.value = value; }

    public void updateValue(ItemChangeEvent event) {
        logger.info("got itemchangedevent");
        setValue(event.getNewItemName());
    }

}

my problem now is, that the ui:include always using an old bean value.. so if i click on the fist button, the bean-value is correct but the ui:include shows nothing, if i click second, the ui:include shows the first template and the bean the second value..

i think i have some trouble with the lifecycle but i acutally dont know how the fix it..

any help would be great =)

Hi Falk, could you please try to replace ui:include with ui:decorate ?

[dragnic]

thx lukas for your reply

i tried to replace the ui:include line as followed:

<ui:decorate template="#{fgr.value}" />

but it generates a stack overflow.. debug console told be that it repeatedly gets "an cached instance of singleton bean 'fgr'

maybe i have to add, that i am using spring

[ilya_shaikovsky]

add layout="block" to outputPanel and please check a4j:log for any problems. actually that should not be client side problem at all but that's all I could propose for now as seeing not much difference between your code and http://richfaces-showcase.appspot.com/richfaces/component-sample.jsf?demo=panelMenu&skin=blueSky

hey guys.. sorry that it took so long to answer again...

depending on this article: http://primefaces.prime.com.tr/forum/viewtopic.php?f=3&t=1251 now is choose a different way, because i dont really want to hack the lifecycle..

now i use a solution that is very similar to the richfaces tabs .. menu is the same but the content part now looks like this:

<a4j:outputPanel id='#{targetId}'>

            <c:forEach items='#{items}' var='item'>

                <a4j:outputPanel id='content_#{item.id}' rendered='#{bufferBean.value == item.template}'>

                    <ui:include src='#{item.template}' />

                </a4j:outputPanel>           

            </c:forEach>

</a4j:outputPanel>

so i process every template that is adressed by a menu, but i only render the actual one

thanks for you help.. actually i am not happy with this, but it seems to be a stable solution
