Hi

I'm using Hibernate 2.1.2 with jdk 1.3.1_09

I'm inserting an object that has an empty List. I commit the object and do a session.clear ().

Using the same session I use the "find" method to obtain the object. When I get the collection and add an element using the "add" method I get:

java.lang.NullPointerException

void net.sf.hibernate.impl.SessionImpl.dirty(net.sf.hibernate.collection.PersistentCollection)

SessionImpl.java:3190

void net.sf.hibernate.collection.PersistentCollection.write()

PersistentCollection.java:86

boolean net.sf.hibernate.collection.List.add(java.lang.Object)

List.java:129

Thanks in advance for the help

Please submit a simple test case to JIRA, so that I can reproduce this. It looks like you are doing a Bad Thing, but the NPE is a bad exception.
