I'm doing a "long running transaction" in a JSF app - fetch the object for edit in one request, post the form/apply values, persist with saveOrUpdate().
Everything worked great until I put in the superclass with it's persistent properties, and now I'm getting the LazyInitializationException on a setter referencing the owning session being closed.
I've confirmed that everything works as I intend WITHOUT the superclass, but as soon as that is placed back in the hierarchy I get the exception above.
Any tips/suggestions would be greatly appreciated, as using the same superclass in other places in the app - doing essentially the same Crud operations works fine... I'm a bit confused and look forward to your insight. Any other thoughts are welcome too :)
Thanks,
