Hi, we have a very same problem. There is a requirement to edit process definition on fly (workflow composition by common user, not developer). So, we have template process definition, which can be customized through some interface. The result should be modified copy of template process definition. The mentioned issue with Hibernate we have already faced. Any hint, about the best way for that.
