Eric,
Looks like you just need to change
<s:hidden name="user.id" />
to
<s:hidden name="user" />
What is going on right now is your form contains a field user.id=X so
Stripes is creating a new User object for you and filling in the id
property. What you want to do is pass user=X so the TypeConverter kicks
in and pulls the User from the DB.
