Although the original design principle of MVVM pattern is that ViewModel doesn't have any reference to UI components, ZK provide ways to retrieve UI components on a ZUL in a ViewModel. One is passing components as parameters in binding expression. Another is to wire components by Selector. This way enables you to wire components with @Wire like you do in a SelectorComposer.
Example to wire components in a ViewModel
public class SearchAutowireVM{
//UI component
@Wire("#msgPopup")
Popup popup;
@Wire("#msg")
Label msg;
}
- Use @ContextParam(ContextType.VIEW) to retrieve root component. (line 11)
