I have a parent child relationship

Parent Entity Child Entity, when I persist the child enity I wish to persist the parent.

childEntity.persist()

The parent enity id is autogenerated when persisted.

As you can guess when I call childEntity.persist() I get the id must be set for the parentEntity, before the childEnity can be persisted.

when I call childEnity.persist() I want hibernate to carry out the following actions:

parentEnity.persist()
childEntity.persist()

In my childEnity i have the following relation ship set up


@NotNull
@ManyToOne(cascade = CascadeType.ALL, targetEntity = ParentEntity.class)
@JoinColumn(name="child_parent_id", referencedColumnName="parent_id")
private ParentEntity applicant;

As mentioned it does not work, do I need to set anything else. To get cascade to work , an just want to check you can cascade from child to parent, as well as parent down to child

Cheers

It does work in a fashion, I have just found out that the parentId is not autogenerated but set by a aspect when parentEntity.persist() is called.

But debugging through the code.

If childEnity.persist() is called it wont call my parentEnity.persist() in my parentEntity_roo.aj.

It will persist under the covers.

So I guess in cases like this you either have auto generation set or you set the id first.
