Hi,

I have the following relationship defined for 2 classes.

Student -> Account and Account -> Student.

When I load the student and detach the object for editing in a jsp, the account is set too LAZY loading. After I edit the Student and save it, because the Student object no longer have a reference to Account, it removes the relationship.

Can someone please tell me how to avoid this?

Thanks in advance.

You should use merge() to save the edited Student object and be careful no change the Account field.

Also, I recommend you to read this short, but enligtening article about different persisting methods.
