You are trying to add logic to your UiBinder XML file which is not what it
is intended to do. View-specific logic goes in the java code.
Just do it in the constructor or if you are caching your views (which is
good for performance) in a dedicated method that can be called before the
view is rendered by your Activity.
For the sake of an example, lets assume your UiBinder class is called
MyView.
public class MyView extends Composite {
//definition of UiBinder interface and instance
@UiField
FinishButton finish;
public MyView(){
initWidget(binder.initAndBindUi(this));
}
public MyView(Rights permissions){
this();
updateUi(permissions);
}
public void updateUi(Rights permissions){
if( permissions == FINISH_ORDER || permissions == CANCEL_ORDER )
finish.setVisible(true);
}
@UiHandler("finish")
void onClickFinish(ClickEvent e){
//handle the click
}
}
