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.
public class MyView extends Composite {
//definition of UiBinder interface and instance@UiFieldFinishButton 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}
}
