code: @Override
  	protected void afterPaint(final RenderContext renderContext) {
  		super.afterPaint(renderContext);
  
  		final int size = getChildCount();
  
  		for (int i = 0; i < size; i++) {
  			WComponent child = getChildAt(i);
  			child.reset();
  		}
  	}
docs: After the component has been painted, the UIContexts for this component and all its children are cleared.
  
  @param renderContext the renderContext to send output to.
