Deleted entity passed to persist exception

Question

I have this kind of entities:

Document | n .. to ..1 | DocumentType | 1 .. to .. n | PropertyType | 1 .. to .. n | DocumentProperty

I simply try to remove a document like: entityManager.remove(document);

but an error is firing:

16:45:51,499 ERROR [[Seam Resource Servlet]] Servlet.service() for servlet Seam Resource Servlet threw exception javax.persistence.EntityNotFoundException: deleted entity passed to persist: [up.docstore.PropertyType#]

The problem seems to come from here:

@OneToMany(mappedBy = "documentType", cascade = {CascadeType.ALL}, fetch = FetchType.EAGER)
@ForeignKey(name = "FK_DOCUMENT_TYPE__PROPERTY_TYPE")
@Sort(type = SortType.NATURAL)
private SortedSet<PropertyType> propertyTypes = new TreeSet<PropertyType>();

If i remove CascadeType.PERSIST all it's working. But i need it there and also i need it EAGERLY.

Does anyone know other solution?

Edit: removed DELETE_ORPHAN cascade, but still the same problem.

Answer 1

Solution:

• There was a CascadeType.REMOVE in a @ManyToOne relationship ! Removed it.

Why this solution?

• if you want to delete a child you SURELY do not want to delete its parent because there can be other children related to that parent.

Answer 2

I assume you have called remove() on an of type PropertyType before. Call remove() only for the "root" entity, and remove the others with something like:

document.getDocumentType().getPropertyTypes().remove(propertyType);

And retain the DELETE_ORPHAN

You can then, after verifying you haven't manually called remove() on other entities, try calling:

document = entityManager.merge(document);
entityManager.remove(document);

so that the EntityManager reassociates the object with the session first.
