Illegal attempt to associate a collection with two open sessions
Ozkar
y no he podido darle solucion.
Generalmente yo tomo los objetos tras buscarlos en un query y obtener
una coleccion, de esa coleccion tomo uno en particular y en ocasiones
necesito hacer modificaciones al objeto pero cuando intento guardarlo
ya sea con un update o un saveorupdate me arroja esta excepcion.
¿Cómo es la forma correcta de hacer este tipo de operaciones?, ya lo
he googoleado pero no me aclara al 100% mi duda y sigo con el
problema.
por cierto, estoy usando Icefaces 1.8.1, Hibernate, netbeans y
glassfish v3
