Hello,

I'm having problems trying to update an object with a collection associated that was previously retrieved. If someone has faced the problem before it would be a great help.

The simplified code is the following:





Basicly the code that produces the exception is:


The implementation of saveMessage is:



I got the so called Illegal attempt to associate a collection with two open sessions in the getHibernateTemplate.saveOrUpdate(receiver); sentence. Any idea?

By the way I read around that it would be necessary to evict the object but I shouldn't evict the object out of the saveMessage for design reasons.
