I need to communicate objects (data) between two pages .
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.

chillworld ( 2014-03-13 22:21:51 +0800 )editok, 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?
chillworld ( 2014-03-13 16:13:04 +0800 )editno in the same pc ! the click on the button should redirect me to page b and the data show appears in page b.
BenAmarMahdi ( 2014-03-13 17:04:17 +0800 )editplease , is there anything to add to ZUL pages ?? because i have tried the same solution from the beggining and it didn't work.
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?
