Hi,
Still waiting fior reply. In the meantime i want to clear onething that the problem is not specifically related to the use of popup (or lookup). Even if i use combo box with showing the service type name on front and at the backend having its value as it primary key the problem also came. I went through my copy of "Hibernate in Action" and in chapter i found a paragraph mentioning hibernate working on this and it appears from there that hibernate checks the value of primary key for not null and also if it found version number than checks its as well so there the root of problem ( i am not saying that hibernate is doing anything wrong there u ppl are best at ORM and i know that it is a difficult topic and hats off to u r great work).Can u suggest any alternative here or how would u handle the situation with say combobox or lookup (specially the lookup as my main page dont fetch all the service types). One of the solution struck to my mind was to make an inetrceptor and then seeing that if primary key is set than the object is not transient. Is this a good thing to do and any alternatives u ppl can suggest.
For u r refernce these rae my objects and mappings (using annotations)
