It's not that easy because injection works with Tapestry-handled object
(via annotation or specification).
You need your "visit" state object, and to access a state objet you must
have an access to the "tapestry.state.ApplicationStateManager" service
point. I see to solutions:
1. The simplest: pass your user as a parameter to your "create"
function, or to some kind of «prepareForCommit».
2. My prefered: use HiveMind to provide a DAO that will take the
responsibility of setting the user on the created objet. You'll
have to inject the tapestry.state.ApplicationStateManager
service to this DAO in your hivemodule.xml.

Hope this helps.
