LazyInitializationException|no session or session was closed

Hi,

I'm runnig Hibernate 3.1 in a JSF Framework on Tomcat5.5.

Got 2 lazy loaded collections: containedPropertiesA, containedPropertiesB (Both have identical mappings)

My Problem is that after successfully fetching containedPropertiesA I want to fetch containedPropertiesB with the same session. While doing so hibernate crashes with:

Code:

ERROR [http-8880-Processor24] - failed to lazily initialize a collection of role: foo.bar.containedPropertiesB, no session or session was closed (LazyInitializationException.java:19)
org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role: foo.bar.containedPropertiesB, no session or session was closed
   at org.hibernate.collection.AbstractPersistentCollection.throwLazyInitializationException(AbstractPersistentCollection.java:358)
   at org.hibernate.collection.AbstractPersistentCollection.throwLazyInitializationExceptionIfNotConnected(AbstractPersistentCollection.java:350)
   at org.hibernate.collection.AbstractPersistentCollection.initialize(AbstractPersistentCollection.java:343)
   at org.hibernate.collection.AbstractPersistentCollection.read(AbstractPersistentCollection.java:86)
   at org.hibernate.collection.PersistentSet.toString(PersistentSet.java:253)

The thing I'm currently racking my brains on is, that at the point when hibernate calls the proxy for containedPropertiesB my Debuger tells me there is still a session that could be used für lazy loading.

Thanks for any help! If you need more information, just point out what you need.

@MikePloed: THX four your proposal but I already read

http://www.hibernate.org/42.html
http://www.hibernate.org/43.html

some others and googled for a while.

My symptoms look like I've got another error. Here is some additional Information:

1. I've got an running Interceptor for some month now
2. My page is not rendered when I call the Hibernate proxy
3. My Debugger says there is still an open session ?!?
