Error when trying to get data from associated object
I'm having some problems with my program. I'm relativly new to Seam, but I have been looking for an answer to this problem for about a week now through this site and various others and am still stuck.
My environment is as follows:
Windows XP
Eclipse 3.3.2
JDK 5.10
JBossTools 2.1.2 GA
Seam 2.0.2 SP1
JBossAS 4.2.2 GA
I've attached what I think is reivant code below. The basic code was produced by the JBoss Tools Let me know if you need to see somthing else. The flow I go through is creating a Line and saving it. Create a Series, associate it to a Line and save it. All is good at this point and the database is updated correctly upon visual validation.
Here's where the problem happens. At this point any attempt to get the details of a Line results in an error.
Error listing for a Line detail is:
