Java.lang.IllegalStateException: Objeto ya no es administrado por Realm. ¿Se ha eliminado?

Estoy aprendiendo Realm y Recyclerview. Hice una aplicación sencilla donde puedes agregar elementos y eliminarlos. Todo está funcionando bien hasta que empiece a eliminar el elemento uno por uno. En el último elemento cuando hago clic en Eliminar me dan una excepción

java.lang.IllegalStateException: Object is no longer managed by Realm. Has it been deleted?

Este es mi codigo

  @Override public void onDeleteClick(int position) { mRealm.beginTransaction(); mResult.get(position).deleteFromRealm(); mRealm.commitTransaction(); adapter.notifyItemRemoved(position); }

Aquí está la pila completa

Ok gracias a Christian Melchior por ayuda. He arreglado mi código haciendo esto

antes de

  @Override public void onBindViewHolder(MyListViewHolder holder, int position) { Persons p = persons.get(position); holder.firstName.setText(p.getFirstName()); holder.lastName.setText(p.getLastName()); }

Después

  @Override public void onBindViewHolder(MyListViewHolder holder, int position) { if (persons.get(position).isValid()) { Persons p = persons.get(position); holder.firstName.setText(p.getFirstName()); holder.lastName.setText(p.getLastName()); } }
