stackoverflow businesskey on foreign keys

[GoogleCodeExporter]

What steps will reproduce the problem?
1. have a parent child relation
2. add businesskey on foreign key and another
3. equals and hashcode using BusinessIdentity

What is the expected output? What do you see instead?

Are the parent and the child instances pointing to the same instance?
Like this:
Class A {
  @BusinessKey
  private A parent;
}

And in Runtime you're doing:
A instance = new A();
instance.parent = instance;
instance.toString();

-- This would clearly create an infinite recursion as the Identity of 
'instance' is dependent on evaluating 'instance'.

If the example above isn't what is going on, can you please attach a code 
sample for the issue you're facing?

Thank you.

Hi,
I belive this is not the case. I'll see if I can reproduce this error in a demo 
project. However, this is the structure:

Class A:
    @BusinessKey
    @JoinColumn(name = "attribute", referencedColumnName = "attribute_name")
    @ManyToOne(optional = false)
    private B attribute;
    @BusinessKey
    @JoinColumn(name = "user_id", referencedColumnName = "id")
    @ManyToOne(optional = false)
    private C userId;
    @BusinessKey
    @JoinColumn(name = "service", referencedColumnName = "id")
    @ManyToOne(optional = false)
    private D service;

Class B:
    @OneToMany(cascade = CascadeType.ALL, mappedBy = "attribute")
    private Collection<A> ACollection;

Class C:
    @OneToMany(cascade = CascadeType.ALL, mappedBy = "userId", orphanRemoval = true)
    private Collection<A> ACollection;

Class D:
    @OneToMany(cascade = CascadeType.ALL, mappedBy = "service", orphanRemoval = true)
    private Collection<A> ACollection;

best regards,
hw

If Class A holds an entry to Class B, and Class B has Collection of Class A, 
doesn't that create a cyclic infinite reference?

Can you please include the equals implementation for A, B, C and D?
I don't see BusinessKey in the B, C or D classes.

Helge,
I haven't heard back from you with regards to this issue.
I am closing this issue as invalid for now, please feel free to comment or 
include a sample to demonstrate the issue, if so, I'll re-open it.

Thank you for your continued interest in OpenPojo.
