How to force a datatype Selection with required?

Hi to you all.
Working with new classes and templates of my installation of ez 3.9rc1 I noted a strange thing.
I created a new class object for a form to compile.
Many of the attributes are Selection datatype type. I added options in this way:
1. Select from the list
2. Option a
3. Option b
4. Option c
and so on.
The problem is that the attribute is required, but with the line 1 if the user don't make a selection the object is stored anyway.
There is some trick to change this fact?
Something like a template code block?
Thanks in advance.
