I have a parent child relationship

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

childEntity.persist()

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:

call the parentEnity_roo.aj method persist() this will then call a aspect which will populate the parentId
Then call the childEntity_roo.aj method 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

Should calling childEntity.persist() then call the parentEntity.aj persist() method before it calls the childEntity.aj persist() method.

Or does calling childEntity.persist() only call childEntity.aj persist() and the parentEntity is persisted under the covers as part of the childEntity.persist() call.

If this is so then my aspect will never be called an I will need to rethink the logic.

Thanks for any help
