Hi,
I was facing lazyinitialization problem and used OpenSessionInViewFilter to avoid it. This worked in some places but failed in others. All the errors come in the hashCode() method that I have implemented in my POJO's. These come for the objects which are retreived as Lazy.
I have a basic question which may be very stupid, but please bear with me.
Can I change the hashCode() method to include only those objects that are not fetched lazily? What would be the side effects in such a case?Could any one please help me with this? Am stuck with this problem for a long time now.

Thanks
