You cannot remove an instance which is detached from hibernate
.
You need to first load
the instance and then do any update operation on that instance.

Want to delete with HibernateUtils, but it throws exception
문제
I just want to delete vPref from my db, but it throws
caused by: java.lang.IllegalArgumentException: Removing a detached instance models.Preference
public void valueChange(Property.ValueChangeEvent event) {
switch ((SelectedDropdownItem) event.getProperty().getValue()) {
default:
if(vPref != null) {
HibernateUtils.delete(vPref);
vPref = null;
}
break;
the vPref cant be null, so I dont even know what the problem.
