Hello ZK warriors.

I´d like to ask if you guys know how to implement data binding using MVC style with ZK 7.

In earlier versions I used to implement like this:

zul´s file:

<?init class="org.zkoss.zkplus.databind.AnnotateDataBinderInit" arg0="./wndIndex"?>
<window id="wndIndex" apply="IndexComposer">
   <textbox id="txtName" value="@{$composer.user.name}" />
</window>

composer´s file:

org.zkoss.zkplus.databind.AnnotateBinder binder

def onCreate_wndIndex(Event event) {
    binder = (AnnotateBinder) event.target.getAttribute("binder", true);
}

but in ZK 7 the classes from org.zkoss.zkplus.databind.* are now deprecated.

Which classes should I use now? Does someone have a working example?

Best regards,

Felipe Ribeiro

Hi Felipe Ribeiro,

Here I'll rewrite the above code in MVC Style...

In Zul page:

<window id="wndIndex" apply="packageName.JavaClassname">
       <textbox id="txtName" />
</window>

In Java Class:

public class JavaClassName extends GenericForwardComposer // ! IMPORTANT
{
    Window wndIndex;
    Textbox txtName;

   public void doAfterCompose(Component comp) throws Exception 
   {
       super.doAfterCompose(comp);

       win_parentportal.setAttribute("win_parentportal", this);

    someMethodName();
    }
    public void someMethodName()
      {
             txtName.setValue("Hello"); OR
             txtName.setText("Hello"); 
      }
}

Here extending GenericForwardComposer is importsnt to bind.

Greetings..
