There is still a problem using children of a model. If you call customer.address.street, it expects that the customer contains an empty address object, while in most applications, this contains null on a newly created object. Patrick mentioned that he is researching how to use the OGNL NullHandler (http://www.ognl.org/2.6.0/Documentation/html/nullHandler.html) to solve this problem, but I haven't heard back from him.
