How to get current element in mixin

[Michael]

I need a mixin which can be attached to different elements (with and
without body). The mixin wraps original element with another and adds some
classes to the original. How I can get current element while render? I'd
use writer.getElement() in render body but its not triggered in components
with empty body. In begin render phase writer returns container instead of
current element.

@MixinAfter
public class MyMixin {
   void afterRender(MarkupWriter writer) {
  ListNode children = writer.getElement().getChildren();
  if (!children.isEmpty()) {
 Element lastChild = (Element) children.get(children.size() - 1);
 doStuff(lastChild);
  }
   }
}

There's another solution, but it just works when the component is a  
ClientElement:


@MixinAfter
public class MyMixin {

@InjectContainer
private ClientElement clientElement;

void afterRender(MarkupWriter writer) {
Element element = 
writer.getElementById(clientElement.getClientId());
}

}

I have not tested the code above.
