Good day. As far as documentation states, "The key value includes the key of the entity group parent (if any) and either the app-assigned string ID or the system-generated numeric ID. To create the object with an app- assigned string ID, you create the Key value with the ID and set the field to the value. To create the object with a system-assigned numeric ID, you leave the key field null."
Is this the id that can be accessed via Key#getId() call? I assume it is. My main question is: is this numeric ID guaranteed to be unique for all entities of the same type? If yes, how do you retrieve the entity using this id? I tried using PersistenceManager#getObjectById(), but it does not find my entity. I guess this is related to the fact that my entity is child in an entity group, thus its keys' string representation would not be "MyClass (10)" (which is created when I use KeyFactory to create key from an entity type and a numeric ID) but "MyParent(20)/MyClass(10)".
