I have a 'CountryPrice' entity containing a Map for which the key and value are both entities:
@OneToMany(cascade = ALL, orphanRemoval = true)
@JoinTable(
name = "countryprice_price",
joinColumns = @JoinColumn(name = "countryprice_id", referencedColumnName = "id"),
inverseJoinColumns = @JoinColumn(name = "price_id", referencedColumnName = "id"))
@MapKeyJoinColumn(name = "country_id", referencedColumnName = "id")
public Map<Country, Price> getPrices() {
return prices;
}
The CountryPrice entities have been created and persisted in DB some time ago and normally do not change any more.
From time to time I get the validation exception below after updating other entities that reference this one. Clearing the cache seems to solve the problem for a while.
When debugging my application I found out that during the merge after the commit in the UnitOfWorkImpl class in the method
public Object getOriginalVersionOfObject(Object workingClone)
there is a key but the original object is null. As a consequence a new uninitialized Country object is put in the cache and causes the exception below for subsequent transactions. Unfortunately my knowledge about the eclipselink internals is very limited.
So any idea why the original object is null? Is there anything I can do to avoid this?

What are you doing to get the error, include the code.
So, if you access the Country from the cache after the commit, is its id null?
How have you mapped the id for Country?
Try the latest 2.1 release to see if the issue has been fixed.
From the stack I noticed you don't seem to be using weaving, try using static or dynamic weaving.
