Andrew I totally agree with you on "its the desired behavior of a session bean -- one instance for the user's session" But is their a way to recreate the instance of backing bean in following situations 1) Whenever a new record is inserted into database. The reason i mention this is my backing bean instantiates the pojo and for subsequent save into database the backing bean holds onto the old instance of pojo having same identifier (ID) value. This is exactly the reason Hibernate throws Detached Object Exception passed to Persist
2) Whenever i navigate between JSF pages , i wanna backing bean to be re-initialized i.e. re-created with new instance Please note as suggested by you i am not looking to clear off the fields on the form whereas i want to recreate the whole backing bean itself Any pointers/suggestions highly appreciated Regards Bansi Andrew Robinson-5 wrote: > > That is the desired behavior of a session bean -- one instance for the > user's session.
