Get the validation message for a specific component

Answer 1

How about this java method

public String getComponentMessageDetail(String cid){
  FacesContext ctxt  =  FacesContext.getCurrentInstance();
  Iterator cm = ctxt.getMessages(cid);
  List msg = new ArrayList<>();
  while(cm.hasNext()) {
    msg.add(cm.next().getDetail());
  }
  return String.join(" | ", msg);
}

to show everything what's in the message cache?

Also in xhtml
