Hi,
I am implementing call back methods from net.sf.hibernate.Lifecycle. But the insert query is not generated and sequence generation. Do i have to do something in onLoad() in the class which is implementing the Lifecycle interface.
THe stack trace which i get after implementing Lifecycle is :
6:42:23,823 DEBUG SessionImpl:413 - opened session

While the stack trace after removing the Lifecycle interface from the class which implemented it is :

Did anyone face this before ? May be i am missing something. Please help.

i got the solution for the problem i posted....i was saying return true for onSave() which i replaced with return NO_VETO.
Please delete this thread.
