How to set common styleClass when component is required, readonly or disabled

This is to show how to highlight input components globally when it is either required, readonly, or disabled.

1. Create a class that is extending the javax.faces.application.ViewHandlerWrapper.

public class MyViewHandlerWrapper extends ViewHandlerWrapper {

}

2. Overrider the renderView method.

@Override
public void renderView(FacesContext fc, UIViewRoot view) throws IOException, FacesException {

  super.renderView(fc, view);

}

3. create a private method to find input components recursively and highlight them based on the required, readonly and disabled attribute.

Loop every components in a ViewRoot recursively

1. Writing the recursive method.

private void loopComponentsRecursively(List<UIComponent> childrenList) {
  for(UIComponent component : childrenList) {
   if(component.getChildCount() > 0) {
    loopComponentsRecursively(component.getChildren());
   } else {
    // no more children for this component
    System.out.println("child: " + component.getId() + "  " + component.getClientId());
   }
  }
}

2. Invoking the recursive method

// some code
loopComponentsRecursively(viewRoot.getChildren());
//some other code

How to handle localized resources with resource bundle

Generally, there are 2 ways to handle localized resources.
1. Append the locale name to the end of the file name. eg, logo_en_US.jpg, flag_zh_CN.png
2. Save the resources of the locale to individual resource bundle.

Solution 1 is kind of straight forward,

thus, in this post, we will be focusing on Solution 2. 

Normally, in java development, we have different resource bundle to handle localized messages, labels for different locales. 

eg, system-messages_en_US.properties, system-messages_ms_MY.properties, etc
