<class name="StateNodeState">
  <composite-id name="id">
    <key-many-to-one name="parentNode"/> <!-- class="StateNodeImpl" -->
    <key-property name="stateName"/> <!-- type="String"-->
  </composite-id>
  <one-to-one name="state" foreign-key="state" class="StateNodeImpl"/>
</class>

public class StateNodeState {
	
	private StateNodeStatePK id;
	private StateNodeImpl state;

// here come setters and getters...
// ...
}

public class StateNodeStatePK implements Serializable {
	
	private StateNodeImpl parentNode;
	private String stateName;
// here come setters and getters...
// ...
}


<class name="StateNodeImpl" table="StateNode">
  <id name="id"> <!-- Long -->
    <generator class="foreign">
	<param name="property">parentStateState</param>
    </generator>
  </id>
  <property name="stateName"/>
  <property name="stateValue"/>
  <one-to-one name="parentStateState" property-ref="state"/> <!-- class=StateNodeState -->
  <many-to-one name="parentState"/> <!-- class="StateNodeImpl" -->
</class>

public class StateNodeImpl {
	private Long id;
	private String stateName;
	private Long stateValue;
	
	private StateNodeImpl parentState;
	private StateNodeState parentStateState;
  // here comes auto generated setters and getters...
  // ...
}

I also tried without it without the <generator class="foreign"> and the reverse one-to-one from StateNode to StateNodeState, the result was the same.
