Hello,
I have encountered a strange problem.
I'm using JBoss4.0.4GA with EJB3.
I have a global ID scheme for all my "Entity" beans, the IDs are generated by a
TableGenerator, and are Longs which start with 100.000 and count upwards.
I have an instance of bean A with a many-to-one relationship to instances of
bean B. Recently I got the follwing exception when loading an certain instance
of A from the DB:
javax.persistence.EntityNotFoundException: Unable to find {bean B} with id
87005
Which is pefectly sane, because there is no bean B with this ID (I checked in
the DB). But I also found in the DB that in the row for bean A, in the column
where B's Id should be found, there was indeed the value '87005'. That ID can
never have existed before, because as I said, they started with 100.000 and
count upwards.
Does anyone have an explanation for that behaviour? Why was this impossible ID
ever written to the DB?
It is not reproducable, I have many rows in the table for bean A where the
relationship to B is just fine. This occured for only 6 of about 6000 beans of
type A.
