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:

Still trying to sort this one out. I changed the collection on Line to be eager fetched (not that that is what I want in the long term...) and I'm still getting an error. I'm really stumped on this.

OK... If I change the Set to a List, everything works! Again, not what my desired implementation is. :( I do notice that hashcode() is mentioned in the error trace, but I'm not seeing anything wrong with my hashcode() implementation.

Can someone please take a look at this and see what's going on? I've searched and found others having similar problems and there have been no solutions to those postings either.

The problem ended up being that datalist does not accept a Set and needs a list. I added this to my entity 

    @Transient
    public List<Series> getSeriesList() {
        return new ArrayList<Series>(series);
    }

and my view to get that instead of the set version to load the list.
