Dear Onur,
That was a great help, and makes it much more simple.
Yesterday i have give up and wrote a decode methode to get the id of the
submited component, but with ActionListener its much more elegant.
Thanks
Hanspeter
For other beginers, here the code:
---------------------------------------------
import javax.faces.event.ActionEvent;
public void doAction (ActionEvent e) {
UIComponent component = e.getComponent();
FacesContext context = FacesContext.getCurrentInstance();
String nodeId = component.getClientId(context);
}
MethodBinding:
MethodBinding mb =
context.getApplication().createMethodBinding("#{DummyBean.doAction }", new
Class[]{ActionEvent.class});
linkItem.setActionListener(mb);

Hi,
Change doAction method to action listener type, and change in your code
linkItem.setAction(mb); ---> linkItem.setActionListener(mb);
Now You got an ActionEvent object in your actionListener,
Hope it helps,
Regards,
Onur
