 Post subject: @ManyToOne cascades merge to parent when I don't want it to

I have a parent class (called MasterProduct) that has a OneToMany relationship to a set of children (class called Variant). The mapping of the objects
if done using hibernate annotations, see below:


Annotation on many to one side:
Code:
@ManyToOne(cascade = {CascadeType.PERSIST, CascadeType.REFRESH}, fetch = FetchType.LAZY)
@JoinColumn(name = Columns.MASTER_PRODUCT, nullable = false)
private MasterProduct masterProduct;



Annotation on one to many side:

Code:
@OneToMany(fetch = FetchType.LAZY, mappedBy = Variant.Attributes.MASTER_PRODUCT)
@OnDelete(action=OnDeleteAction.CASCADE)
@Cascade(value={CascadeType.ALL, CascadeType.DELETE_ORPHAN})
private Set<Variant> variants;


I have a scenario that I have written a JUnit test for which fails. This is what I want to do:

1. Load a Master Product through hibernate from the database
2. Remove a single variant from its set of children
3. Create a new variant passing the master product as the parent to the constructor
4. Call merge() on the variant to persist it to the database.
5. Re-load the Master product from the database

NOTE: I am only calling merge on the new Variant. I have not called merge or any form of persist on the Master Product.

I expect the reloaded MasterProduct to contain the new Variant and also the removed Variant. The removal of the variant should never have been persisted
since I only merged the Variant, not the parent Master Product.

i.e. The test does not save the modified master product and saving the variant should not cascade to the master product.

Unfortunately the JUnit test fails - the master product once reloaded contains the new variant and not the removed variant. Basically the merge() of the
variant cascaded to the master product and then to it's children and persisted the variant remove.

The following line of code is where the test fails[b]
Code:
// we expect the variant count to be one greater than before since we added a new variant.
// the variant we removed should not have been persisted to the database. Therefore it shouldn't
// be removed.
assertEquals("Unexpected number of variants for the CP650.", expectedVariantCount + 1, reloadedVariants.size());


I expect I have made an error in my annotations, but I cannot spot it. Any help would be much appreciated.

[b]Hibernate version:3.2.0.cr2 (annotations 3.2.0.cr1)




The junit test code failing:
Code:

has anyone managed to look into this for me? I am really stumped and cannot solve the problem.

Thank you very much.

If an object is loaded in a session, then any changes made would automatically get updated because of Hibernate's "automatic dirty checking".

So even though you called merged only on "newVariant", the dirty objects also got updated.

Code:
2006-07-13 15:02:987 [main] DEBUG org.hibernate.engine.CollectionEntry [preFlush() :177] - Collection dirty: [com.dolby.pics.model.impl.MasterProduct.variants#CP650]



You could test this by commenting the line

savedVariant = varDao.merge(newVariant);

and running the test case. Updation and deletion would still take place.


It seems you are using the same session. If you try in a new session (or use session.evict [or session.clear] for the other objects) then you could prevent this.
