Hi:

I have a index page like this....

<?xml version="1.0" encoding="UTF-8"?>
<zk>
<borderlayout id="index1">
<north size="115px">
<borderlayout>
<north size="90px">

</borderlayout>
</zk>

When I load page "rol.zul" first time it work correctly, but if I load another one (anyone)
and try to load "rol.zul" again using the menu option I will get the following error:

org.zkoss.zk.ui.UiException - You cannot access components belong to other desktop

rol.zul is using a controller named rolviewcontroller that is created
on the SessionInit listener class.

Here is the code...

<?init class="org.zkoss.zkplus.databind.AnnotateDataBinderInit" arg0="./winRol"?>

</div>

</zk>

this is the class...

public class RolViewController extends ViewController
{
protected Listbox listbRol;
protected Combobox filt;
protected Button rolCreate, rolUpdate, rolDelete;
protected ListModelList listModelList;
protected Label lbDescRol;

@Override
public void doAfterCompose(Component window) throws Exception {
super.doAfterCompose(window);

baseListBean = new RolListBean("descRol");
baseListBean.setServiceLocator(Main.getServiceLocatorBean());
baseListBean.fillBeanList();

listModelList = new ListModelList();
listModelList.addAll(baseListBean.getBeanList());
listbRol.setModel(listModelList);
listbRol.setItemRenderer(this);

listbRol.addEventListener("onSelect", new EventListener() {
@Override
public void onEvent(Event event) throws Exception {
int index = listbRol.getSelectedIndex();

RolViewBean rolViewBean = (RolViewBean) listModelList.get(index);
lbDescRol.setValue(rolViewBean.getDescRol());
}

});

}

@Override
public void render(Listitem listItem, Object data) throws Exception {
RolViewBean rol = (RolViewBean ) data;
(new Listcell(rol.getDescRol())).setParent(listItem);
}

@Override
public void render(Comboitem arg0, Object arg1) throws Exception {
}

/**
}


this is the listener class...

public class CetSessionInit implements SessionInit {

@Override
public void init(Session session, Object request) throws Exception {
CompoViewController compoControler = new CompoViewController();
session.setAttribute("compoControler", compoControler);

RolViewController rolController = new RolViewController();
session.setAttribute("rolController", rolController);

return;
}
}

this is the zul.xml

<zk>
<listener>
<description>MyController Session Initialiser</description>
<listener-class>cet.controller.CetSessionInit</listener-class>
</listener>

</zk>

Did anyone knows what this happen and how can be avoid?
RolviewController is share controller (another zul page use it) so I need it to be a singleton.

Regards, Reynaldo.
