After migrating to spring 3.1.0 from spring 3.0.5 hibernate save method is encountering problem with detached object - when trying to save new object with saveOrUpdate(Object obj) method where obj has no id.

Class A has Set of Class B. when trying to save new instance of class B from <form:form modelAttribute="b"> and via @ModelAttribute("b") it's overriding all the previous set of b's (Set<B>) from class A. Unit testing has no issues, so it could be webmvc issue. It used work perfectly fine with 3.0.5 refer to this forum thread for detailed information.

Affects: 3.1.1

I figured out the problem.
The new feature binding @PathVariable to @ModelAttribute got me confused. So I guess I have close this issue but I can't find?

I'll do that and would you mind adding a small amount of detail for future reference and for our benefit?
