I am trying to show and hide rows dynamically on my page.firstly I tryed to make it on .zul page but I could not refresh component with annotadeDatabinder. Now I am trying to make it on controller java file but now I am facing with problem that if I use for component(like listbox) forward ="onSelect=onSelected(paramA)" then on controller I am tringto catch it like

public void onSelected(ForwardEvent event , String pram){ } this does not work.If I use without second parameter it works. But I should send some string to check it. İs there any way?
