session-scoped backing beans are going to be serialized into your session.
Any properties not marked transient on a serialized object are also
going to be serialized.
Try marking your object reference as transient.
Converters are used to convert objects into string representations on
your components stored in the html response (ie, the form values), and
vise-versa.
They don't directly interact with session-scoped backing beans.
