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

Done!!
