Java.lang.IllegalStateException: The object is no longer managed by Realm. Has it been deleted?

Question

I am studying Realm and Recyclerview. I made a simple application where you can just add items and delete them. Everything works fine until I start deleting the item one by one. In the very last paragraph, when I click delete, it gives me an exception

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

This is my code.

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

Here is the full stack

Well thanks to Christian Melchior for help. I fixed my code by doing this

Before

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

After

  @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()); } }
