I usually have a list field which contains the serializable row
objects. This field is not transient. If you need the datamodel for
the datatable use a transient field for this and check in the getter
method for this field if the transient field and initialize it if it
is null. Doing so saves you a lot of time since writing the
serialization is not required any more.
