Hi,
I have a small question regarding the instantiation of entites inside other entites.

Lets say the following:
class Info {
private PhoneNumber phone;
private Email mail;

}

now when I am in the view and want to use the info.phone.description I would have had to write "private PhoneNumber phone = new PhoneNumber" instead, however I only want to do this if the customer decides to really enter one, otherwise there are lots of blanks in the DB... if I do as I want, I get a "not-null property references a null or transient value property"-Exception... Do you have any clues on how to solve this problem?
Thanks!
