well ... i would like to share my experience with you.. i used the hibernate in a scenario where.. i have some classes for master,detail and sub detail tables. mapped..
i had 2 cases 1- for new record. of master detail and sub detail..(this time all records are assumed to be new) 2- for editing.. here i can't ensure, what are the data user will delete,add and edit.. for example.. he first delete the existing detail,with sub detail. then updated old data.. then inserted new data..in detail and in sub detail.. and then deleted newly entered data again.. and then inserted new data again in detail and sub detail with different values..
now i master object.. and all details and sub details are associated with.. i don't find any built in functionality at that time in hibernate which gives me the facility to just call a single method.. and it will consolidated records in memory and records in database.. accordingly.. got it.? not even merge was doing that.. so in order to cope up this problem i maintained the status in pojo's i used to manipulate in order to keep the state of all objects.. and later i consolidate by my self..by getting all records rite now in DB. with the detached objects..
if you experience such problem and got any built in solution kindly let me know too..
