Hello,

I want to call Save in the ctor of every persistent object in my application.

I want to make a businesslayer where nobody can "forget" a save and has not to think about the order of save calls. Also I want a stable GetHashcode() and Equal() Method. So I need the definitive id of the persistent object already on creationtime.

So I have two questions:

1. Because the method CheckNullability is called in Save I will get an exception when I use not-null="true". Why is the check made already in DoSave inside the method Save? Later on (in Flush) the check will be made again.

2. Are there more problems when I do call Save() in the ctor of my persistent objects?

Thank you for anwering my newbie questions.

NHibernate version: 1.0.2

Depending on the id generator type used, the call of "Save" might actually insert new record into database. This is the case when MS SQL identity generator is used, at least.
