Simon, I am already extending CoreRenderKit.
public class PlcRenderKit extends CoreRenderKit { public PlcRenderKit() { super(); } I am not understanding your position. Do you think I could overwrite encodeBegin method and do somethink else? This is CoreRenderKit method. public void encodeBegin(FacesContext context) { /*CoreRenderingContext arc = */new CoreRenderingContext(); // If there's any prior state, make sure our current "add" doesn't drop it DialogServiceImpl.pinPriorState(context); } Thanks a lot. Regards.
