Hello,

I have the object retrieved from a previous session and try to load its lazy collection in a new session:

try {
PersistentSession session = new PersistentSession();
if (!Hibernate.isInitialized(((NetPortalProvider)node).getNetworks()))
{
session.getPersistentSession().lock(((NetPortalProvider)node), LockMode.NONE);
Hibernate.initialize(((NetPortalProvider)node).getNetworks());
}
}
catch(Exception e) {
return null;
}

(PersistentSession is a wrapper for a Hibernate session)

I get this exception on the highlighted line:
"reassociated object has dirty collection reference"

Anyone knows what this means?

TIA,

--steve p.

It means that there are changes to the state of a collection that you just truid to reassociate with lock().

Lock() is for "clean" objects. update() is for dirty ones.

Thanks, Gavin. I'll re-write that stuff.

That is confirmed, on page 118 of the HB reference doc v3.2.2:

"The lock() method also allows an application to reassociate an object with a new session. However, the detached
instance has to be unmodified!"
