Hi,
After migration to version 2.4.2_01, I have noticed a strange problem with persisting object with field that contains @Embeddable object. Please check attached exception.
Relation between entities looks like this:
@Entity public class ProductKit extends BaseEntity implements Serializable, Convertable { (...) @ElementCollection(fetch = FetchType.EAGER) List<ProductSet> productSets;
@Embeddable public class ProductSet implements Serializable { @ManyToMany(fetch = FetchType.EAGER, cascade = CascadeType.ALL) List<ProductDemand> productDemands;
@Entity public class ProductDemand extends BaseEntity implements Serializable, Convertable { @ManyToMany(targetEntity = ProductSet.class, mappedBy = "productDemands") List<ProductSet> productSets;
