Hi All,

While upgrading hibernate 3.1.2 to 3.5.4 we are facing "org.hibernate.LazyInitializationException: could not initialize proxy - no Session" exception while trying to use proxy objects from view layer. We have settings of OpenSessionViewFilter and transactions. We are using it JSF as view layer.

Following are complete exception log -
