UIGraphic accesses lazy loaded data beyond transaction boundaries
-----------------------------------------------------------------
Key: JBSEAM-1967
URL: http://jira.jboss.com/jira/browse/JBSEAM-1967
Project: JBoss Seam
Issue Type: Bug
Components: JSF
Affects Versions: 2.0.0.CR1
Reporter: Christian Bauer
Priority: Minor
I have a lazy loaded byte[] in my domain model which is enhanced with the Hibernate
instrument task. So it's only loaded on access. If I bind this to a
<s:graphicImage>, this loading is triggered after the transaction of the RENDER
RESPONSE phase was committed. In that case, Hibernate will just grab a database connection
to load the property, which will never be closed. JBoss AS doesn't like that:

It seems like this behavior was OK or has change, I didn't get this exception with
Hibernate 3.2.3 but now with Hibernate 3.2.5.
