I have an application in ZK providers in my database, and i have my DAO to return all the names of my database.

And i have this view in ZK:

    <window id="Mnos" border="normal" mode="modal" width="320px"
        viewModel="@id('vm') @init('operator')">
        <listbox model="@load(vm.provider)" onClick="@command('provider', provider = each)"/>


I need that when a user do click in some provider, save a session variable to use in my application, because i have a crud of services and when i create a service i need create the service related with the provider that the user choose in the menu, and i need create workers and i need create a worker related with the provider that the user choose in the menu,

and i have this java class:

public class operator {

    Collection<String> provider = MnoDAO.getAllProvidersByName();

    public Collection<String> getMno() {
            return mno;
    public void saludo(@BindingParam("provider") String provider){
        Messagebox.show("Hola ... "+mnoList);


But each is null, and second i do not know how can i save a sesion variable to use in all application, and this variable can be change when i select other provider.

Somebody can help me?

I don't understand all you are talking about so I made you sample code run, and added functionality to save and load a session attribute. Please have a look at this example code in zk fiddle.

If you click the "run" button at the top you can see it in action. Also notice, that a value stored, will still be available if you close the sample an rerun it (because it is saved to the session).
