Hello,

I'm developing object hierarchy editor. When user clicks 'cancel' button
i would like to overide changes in entity. I'm using load method for
those porpose, but when I try to load a entity which has proxy,
exception (showed below) is thrown.

Is this expected behavior? I think getPersister method should be
called for original class, not proxy class...

Hibernate version:
2.1.6

Full stack trace of any exception that occurs:

load(Object, id) is not intended to take a proxy.

hmm... could you suggest a method for inplace loading part of object
hierarchy (including case when root of this part is a proxy) ?
