Oke, now I get it.

If you are gonna do a sendRedirect to another page, you some options.

Option 1: Do a GET to that zul :

sender :

Executions.sendRedirect("second.zul?username=MyName");

receiver :

String username = Executions.getCurrent().getParameter("username");

Option 2 : Store it in your session scope :

store it :

User currentUser = new User();
Session session = Sessions.getCurrent();
session.setAttribute("user", currentUser);

get it from session :

Session session = Sessions.getCurrent();
User currentUser =(User) session.getAttribute("user");

Option 3 : Do a POST method :

well, search for yourself and you will find it how to do it, lots of examples online and with one of the 2 above it will work also.

Hope this helps you.

Greetz chill.

your welcome. Sorry for confusing but with zk you can add pages to masterpage and so on what mostly creates headaches to people

ok, so this a simple exemple i make to test it between 2 pages a.zul et b.zul

a.zul(sender)

<?page title="a" contentType="text/html;charset=UTF-8"?> <zk> <window title="new page title" border="normal" apply="NouvaPoule.Elevage.controller.aC"> <textbox id="t"/> <button id="b" label="go"/> </window> </zk>


a.controller

`public class aC extends SelectorComposer<window> { @Wire Textbox t;

@Listen("onClick=#b")
public void aa() throws IOException {
    Map<String,Object> args = new HashMap<String,Object>();
    args.put("data", t.getValue());
    BindUtils.postGlobalCommand(null, null, "doSomeThing", args);
    Executions.sendRedirect("b.zul");

} }`


b.zul ( receiver)

<?page title="new page title" contentType="text/html;charset=UTF-8"?> <zk> <window title="new page title" border="normal" apply="NouvaPoule.Elevage.controller.bC"> <label id="l"/> </window> </zk>


b.controller

public class bC extends SelectorComposer<window>{

private static final long serialVersionUID = 1L;

@Wire Label l; @Override public void doAfterCompose(Window comp) throws Exception { super.doAfterCompose(comp);

}

@GlobalCommand
public void doSomeThing(@BindingParam("data") String data){
   l.setValue(data);
}

} `

ah lols oke, I get it, your 2 pages aren't included in one page? so one pc has screen A and other pc has screen B open?

no in the same pc ! the click on the button should redirect me to page b and the data show appears in page b.

post your code and we we will show you where it goes wrong (zul and vm/controller the important piece only) and in what scope are your 2 pages?
