Thanks for help! I understand the problem, but still do not see a way to implement the issue. If I call my DAO directly from the Home class the expression ognl:document.id works fine and all entries are listed. So the instance of the abstract Home knows how to access the object. Why is there a problem to access an object loaded from the spring container
