Debug level Hibernate log excerpt:

Having read the forums and faq, in order to avoid a

LazyInitializationException i added:


I've a login that, if succeded, saves my user ut in a static var.
User is my top obj.
When logingin, if i dont make a mistake, everything goes fine, but if i log in wrongly at first and the right next, i get the dreaded NonUniqueObjectException.
In order to avoid it, i added to my code:

and this works fine so far.
My Q:
am i doing things the right way?
Because i'm afraid this might have consequences i cant foresee...
Thanks in advance
