Hi again =)
I've just started getting this exception inconsistently... sometimes
it happens 3 times in a row, other times I can go all afternoon
without getting it. Once the exception occurs, it will occur every
time the client loads until FDS is restarted.
Note this occurs on multiple collections. I tried setting the
"offending" collection to lazy=false (in Hibernate), and the exception
occurred on a different collection. I can't set every one of my
collections to lazy=false. Especially since at this point, they HAVE
to be lazy for the updateItem via hierarchical values to almost work.
I also noticed that the collection does not necessarily need to have
any items in it. (And possibly is caused specifically by NOT having
any items in it, I can't tell for sure). The collection referenced in
the exception below has no values, and there's another collection in
that same class with values that doesn't seem to cause the exception.
See below the hibernate mapping, and exception output when this
occurs. (Note there are no FDS managed associations for this collection)
Thanks for any insight you have as to what is causing this.
