Hi,
we have an entity which has a many-to-one property that references a
polymorphic entity.
| @ManyToOne(cascade = {CascadeType.MERGE}, fetch = FetchType.EAGER) //
EAGER
| @JoinColumn(name = "wle_mbtid", unique = false, nullable = true,
insertable = true, updatable = true)
| public Musterbestandteil getMusterbestandteil() {
| return this.musterbestandteil;
| }
|
|
The Musterbestandteil class is the base class for several sub-classes. When I
load the property eagerly everything works as expected, but when it is lazily
loaded "instanceof" does not work because the property is some CGLIBxxx class.
Is there a way around this or do I have to load polymorphic relations eagerly.
That would lead into trouble with entities that have more than one polymorphic
x-to-many relations.
Thanks
Stefan
