Re: [eclipselink-users] find after persist is not finding persisted valu

[James Sutherland <jamesssss@xxxxxxxxx>]

Verify that your @PrePersist is being called on persist() and that the Id
value has been assigned after persist().

It is most likely that the event gets raised after persist() already did its
Id check, so the object is not put in the cache.  persist() should probably
take this into account, so please log a bug for this.

As a workaround, call flush(), or assign the Id before calling persist().



Ids are being assigned using @PrePersist methods. We are using UUIDs and
cannot rely on database sequences or jpa generated values.
