I am facing an issue with saving User object containing a reference to the Salutation model class. Even though the Foreign key (salutation_id) in the User table is optional, I am encountering an error when trying to save the User object after merging and flushing the session.
The specific error message states: "object references an unsaved transient instance - save the transient instance before flushing: com.example.model.Salutation". This occurs when attempting to save a User object with a null salutation_id.
It's worth noting that data in the Salutation table has been inserted independently of the User table. The error only occurs when trying to save a User object with a NULL salutation_id.
If anyone has any insights or solutions to this issue, your help would be greatly appreciated.
@Entity
@Table(name = "user")
public class User implements Serializable {
// Class code here
}
@Entity
@Table(name = "salutation")
public class Salutation implements Serializable {
// Class code here
}
// Method for creating and saving objects in the database
public Object create(Object object) {
// Code for transaction handling and saving object
}
Thank you for any assistance you can provide.
