ObjectDB Database Search

We are testing objectDB with a multi thread application. Each thread has it's own entityManager created from a common factory. In one thread we receive sometimes an object from the database with the field that is declared as @Id having the value null (what is not correct, we checked

Hello, I have an entity MyEntity with a collection attribute myCollection. I have an EntityListener on MyEntity with a @PostUpdate method. When I try to access myCollection from the PostUpdate method, this collection is null . If I try to access the collection from the PreUpdate method

Why can the field "contracts" be " null "? ---------- @Entity @Inheritance(strategy = InheritanceType. TABLE_PER_CLASS ) public class Person implements Serializable,Subject {     @Id @GeneratedValue     private long id;     @ManyToMany(fetch = FetchType. EAGER , cascade

we have the critical problem that we receive a null or by zero (in the log a java.lang.ArithmeticException) error for this query: select o from ObjectNode o where o.currentLocation.nodePath = "/(MG)TOOLPOOL-DMC-125U4/(MP)IN" and o.classIdentifier = '(TP)' database can be download from

Objectdb ignores not null annotations

"is not null "-queries are not working correctly for indexed fields. Following SSCCE creates 1000 entities. A null value is assigned to an indexed field for every second entity.
