[jboss-user] [JBoss Seam] - LazyInitializationException and caching

[mrohad]

Hello all!

Code is Entity bean.
and I am caching all Codes using static HashMap..
when I am trying to retieve list of Code and sending the result to my register.jsp i am getting the following exception...

any idea way?
I would like to keep them deattached and I wonder if I can bring all their properties in a non-lazy way?
it seem like there is a problem with the .toString method...

I will be thankfull for any assistance you can provide
