<p dir="auto">I have a form with three levels of nesting. Imagine a group, which has users, which have phone numbers.<br>
The GroupType has the option cascade_validation =&gt; true, and a collection of UserType.<br>
The UserType has the option cascade_validation =&gt; true, and a collection of PhoneType.</p>
<p dir="auto">I have validations defined for the three entities in the file validation.yml, simple NotBlank validations.<br>
The validations of Group and User work perfectly and I get the error when I try to submit the form with blank fields, but if I let the fields of the Phone empty, the form goes ahead and causes a db error because is receiving a null for a non null column.</p>
<p dir="auto">The issue is in beta4, I haven't had time to test it in the RC1, even I haven't seen anything related in the change log.</p>
<p dir="auto">The CSRF token is not regenerated for each request but seems to be session-bound which is a security issue.</p>
