Hi,
i have a mapping for 2 tables with a one-to-many association between them. I habe lazy fetching enabled, and whenever i create an object for table #1 and try to access one of table #2´s properties i get the following exception
net.sf.hibernate.LazyInitializationException: Exception initializing proxy: [de.gebit.ibn.data.IbnKommune#36]

The mapping of the class the error occurs with is the following:
Code:
<?xml version="1.0" encoding="utf-8"?>

I´m jusing Hibernate 2.1. Does anybody know what´s wrong here? Is this a known bug in Hibernate 2.1?
Thanks for any help
