When I got this situation i figured out that the problem was the lack of hashCode and equals. Now that the methods are implemented nothing is changed. Moreover i've tried using a hashCode() that return always 1 and equals() that return always true but *currentQuantity* is still null. -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/787923#787923] Start a new discussion in EJB3 Development at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
