==
<many-to-one name="ActionId" column="action_id" not-null="true" update="false" insert="false"/>
==

1. many to one assumes that it is a mapping for a custom class mapping defined somewhere in the user configuration

2. since the actionId is already mapped there need not be second mapping for the same property of the class;

3. if there is a need to have relationships with Action class then mapping still should be defined in one place only and can be done in 2 ways:
a. via <many-to-one name="action" column="action_id" not-null="true" update="false" insert="false"/>
b. or in the composite key mapping with
<composite-id>
<key-many-to-one name="action" ...

in the both cases getter is supposed to look likethis:
public Action getAction(){..} and accompanied by matching setter
