Hello everyone,


I have problem in trying to make delete orphans works.
The problem is that,
when i remove a child from a list, and save the parent,
the child is still in the database.

The code is like this :



This is the mapping.



I already use "all-delete-orphan" cascade style as suggested in the Hibernate documentation. "21. Example: Parent/Child".
http://docs.jboss.org/hibernate/stable/core/reference/en/html/example-parentchild-cascades.html.
This does not work.
Maybe this is because i use "inverse=false" or the collection is a list?

Please help me.
Thank you in advance.

regards,

I think the reason could be that you are not updating the relation from Child's end. For e.g. you have done:


However you also need to update the Child's reference with some code like:



Try this out. I hope it works.

Thanks riks.java for the response.


However, I still have the question.

In my case, the association is one way (I use "inverse=false").
That is, only the parent references a list of children, but the children do not have a backward reference to the parent.
I find this approach more programmer-friendly : I do not need to concern about the consistency between two ends (parent -> children, children -> parent).


However, I see that this approach prevents Hibernate to correctly remove orphan children when I update the parent.

Anyone knows a solution that does not require backward references please ?
