Hi! I have an entity class with an @ EmbeddedId (field1 int and field2 int). Based on the manual, I understand that making a query just on entity.id.field1 is efficient. Of course, making a query containing the whole EmbeddedId is the ideal case, and I use it, but I need more use cases. My question

Hi! There is entity Journal with @ EmbeddedId JournalId. Id's content can't be seen/modified from ObjectDB Explorer from its class. Ok, I get this. It's an @ EmbeddedId , so it should depend only on its parent. Problem: id's content can't be modified through its parent neither. Scenario: open db in
