I need to update some other object when i update an object: in other words, when i update an object i need to refresh a date in a record of another table. How can I do that?

By reading the doc. Your question is too vague.

I only need to update an object "y" every time that I update the object "x". So I insert in the update method of lifecycle of the object "x" the instruction to do so... but the method update isn't call!

Note that onUpdate() is not called every time the object's persistent state is updated. It is called only when a transient object is passed to Session.update().

So how can I do what I need?

take a look at interceptor, perhaps onFlushDirty solves your problem ?

I still haven't tried this but I want to this.

you create the interceptor the same place where you open the session so you could associate the session to your interceptor if you need the same session.
But I don't know if you can use the session who calls the interceptor in this method of the interceptor.

I want to check changes in a persistent object before update and create a changelog entry so I will try something similar with my interceptor too.
