Some query fail in BinaryLogicOperatorNode.mutateRowValueConstructorSyntaxesIfNecessary when there is a one-to-one bidi relation.

                 Key: HHH-3199
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3199
             Project: Hibernate3
          Issue Type: Bug
          Components: query-hql
    Affects Versions: 3.2.6
         Environment: Hibernate version 3.2.6.ga. Database postgreSQL,
            Reporter: Benjamin Lerman

 When mapping a one-to-one bidi relation with the following mappings :

<hibernate-mapping>
<class lazy="true" name="com.genia.toolbox.model.association.one_to_one_bidi.impl.DriverOneToOneBidiImpl" proxy="com.genia.toolbox.model.association.one_to_one_bidi.DriverOneToOneBidi" table="_driver_one_to_one_bidi">
<id name="identifier" column="_identifier" type="java.lang.Long" unsaved-value="null">
<generator class="hilo"><param name="table">_hibernate_unique_key_169</param></generator>
</id>
<one-to-one cascade="persist,merge,save-update" class="com.genia.toolbox.model.association.one_to_one_bidi.impl.CarOneToOneBidiImpl" name="carInternal" property-ref="driverInternal"/>
</class>
</hibernate-mapping>

and

<hibernate-mapping>
<class lazy="true" name="com.genia.toolbox.model.association.one_to_one_bidi.impl.CarOneToOneBidiImpl" proxy="com.genia.toolbox.model.association.one_to_one_bidi.CarOneToOneBidi" table="_car_one_to_one_bidi">
<id name="identifier" column="_identifier" type="java.lang.Long" unsaved-value="null">
<generator class="hilo"><param name="table">_hibernate_unique_key_181</param></generator>
</id>
<many-to-one cascade="persist,merge,save-update" class="com.genia.toolbox.model.association.one_to_one_bidi.impl.DriverOneToOneBidiImpl" name="driverInternal" column="_driver" unique="true"/>
</class>
</hibernate-mapping>

 the following query:

FROM com.genia.toolbox.model.association.one_to_one_bidi.DriverOneToOneBidi AS a2, com.genia.toolbox.model.association.one_to_one_bidi.CarOneToOneBidi AS a3 WHERE ((a2.carInternal)=(a3))

failed with an exception:

left and right hand sides of a binary logic operator were incompatibile

This is due to the call to the method mutateRowValueConstructorSyntaxesIfNecessary of BinaryLogicOperatorNode.

One of the type is a OneToOneType which returns 0 for getColumnSpan while the other is a ManyToOneType that returns 1. The two values are not equal and an exception is thrown.

 I join to this issue the relevant classes and mappings.
