Hi all,
I don't know where to search anymore, read the forum messages but thery were not of any help. I have three tables: Order, Orderline and Ticket. An Order object have one or more Orderlines, an orderline have one Ticket and a Ticket may belong to one or more Orderlines.
Order -|-----n-< Orderline > -n------|- Ticket
After construction the persist objects I perform a save(Order), which results in the following exception:
Code:
object references an unsaved transient instance - save the transient instance before flushing: TickTicket
org.springframework.dao.InvalidDataAccessApiUsageException: object references an unsaved transient instance - save the transient instance before flushing: TickTicket

Java code (using hibernate 2.1.8):
Code:
TickOrderline tickOrderline = new TickOrderline();
TickOrder tickOrder = new TickOrder();
tickOrder.setTickOrderlines(new HashSet());
tickOrder.getTickOrderlines().add(tickOrderline);
tickOrderline.setTickOrder(tickOrder);
TickTicket tickTicket = new TickTicket();
tickTicket.setTickOrderlines(new HashSet());
tickTicket.getTickOrderlines().add(tickOrderline);
tickOrderline.setTickTicket(tickTicket);
