How to update items in CrudPanel

In a CrudPanel I have the need to update some items (not through the CRUD dialog). Something like this:

    @Transactional
    ...
 
      instance.setSomeAttribute(newValue);
      return savedInstance = instanceRepository.save(instance);

Calling refreshAll on the dataProvider after the update produces the warning Got an RPC for non-existent node: xxxx. Also I guess it is a little expensive to refresh all items if just one changed.

Calling the specific refresh item, on the other side, refreshItem(instance), gives Object of class [...MenuItem] with identifier [xxxx]: optimistic locking failed; nested exception is org.hibernate.StaleObjectStateException: Row was updated or deleted by another transaction (or unsaved-value mapping was incorrect)

I also tried to pass newInstance to refreshItem, same result.

Can somebody indicate how to proceed?

Check equals and hashCode that they don't contain fields that may have changed when you call refreshItem.
