Describe the bug

I want to reload the graph from storage in my tests to check if we persist stuff correctly.
I wanted to use the Reloader for that. We are using a ConcurrentHashMap in our Root Object:

final Map<Class<? extends Test>, Map<UUID, Test>> testMap = new ConcurrentHashMap<>();

static class Test{}

static class Item extends Test{
    public final UUID uuid = UUID.randomUUID();
    public String string;

    public Item(String string) {
        this.string = string;
    }
}

But when reloading the root with reloader.reloadDeep it doesn't load the items from storage.

Number of items in list: 1
Number of items in list after clear: 0 (surprise :) )
Number of items in list after reload: 0
[]

I created a reproducer here:

Hi,
thanks for the reproducer, it simplifies a lot.

When you use the eager storer instance to store the map after adding an item you need to call the storers commit method to persist that change. Just call commit() after the store:

 map.put(item.uuid, item);
 var storer = storageManager.createEagerStorer();
 storer.store(map);
 storer.commit();

Thank you for the quick response. I wish I could read, it's clearly in the docs O.o
Works now
