NOTES* I know the database structure is odd, they will not use numeric generated keys here.
* The error happens when a table is empty. If the table has data, everything works fine.
QUESTIONS:Please let me know how I could set it up where there wouldn't be a failure when the parent tries to load it's children if the children have no data. Due to data archiving, it's quite possible these tables will have no data on occasion.
Thank you in advance for any advice you may provide. I am pretty new to Hibernate, so please be gentle.[/code]
