any help is appreciated

[horrikhalid]

I replace

this code :

<h:commandLink action="#{testBean.save}" rendered="true" ><h:outputText value="#{msg.save}"/></h:commandLink>

by

<h:outputLink  value="javascript:void(0)" >
            <h:outputText value="#{msg.save}"/>
                <a4j:support event="onclick" actionListener="#{testBean.save}" ajaxSingle="true"/>
            </h:outputLink>

and it works fine, but I still have no explication why when I use the standard submition the exception is thrown

[horrikhalid]

Now if I remove

ajaxSingle="true"

I get the previous error, and the parameters send via ajax are:

AJAXREQUEST	_viewRoot
javax.faces.ViewState	j_id5
vmbackoffice:hospital	1
vmbackoffice:j_id14	vmbackoffice:j_id14
vmbackoffice:service	6
vmbackoffice_SUBMIT	1

Thanks nick for yuor reply

First the problem is not related to RF but is JSF 1.2 one, because I do the same test with JSF 2.0 and it passe w/out any exception, I thank the problem is related to the request scope, so to resolve this problem i found 3 solutions that can be helpfuls for ohters who can have the same issue.

1- Use the session scope insted of request scope.

2- In the submit button use aj4:support like this:

<a4j:support event="onclick" actionListener="#{testBean.save}" ajaxSingle="true"/>

you must use  ajaxSingle="true" if not you have the same problem.

3- Use the component binding to load the combobox's items

public HtmlSelectOneMenu getShtmlSelectOneMenu() {

    if (this.shtmlSelectOneMenu == null)
        this.shtmlSelectOneMenu = new HtmlSelectOneMenu();
    Collection list = new ArrayList();
    for (Service h : this.getServices()) {
        list.add(new SelectItem(h.getId(), h.getDesignation()));
    }
    UISelectItems items = new UISelectItems();
    items.setValue(list);
    this.shtmlSelectOneMenu.getChildren().add(items);
    return this.shtmlSelectOneMenu;
    }

and in the xhtml file

<h:selectOneMenu id="service" value="#{testBean.service.id}" binding="#{testBean.shtmlSelectOneMenu}">
 </h:selectOneMenu>

note  there's no f:selecteItems inside the selectOneMenu tag.

I hope that this thread can be helpfuls for everyone.
