Hi.
I implemented a partial update using the interceptor method FindDirty. The system works well except for the only relationship table that is persisted every time I flush, indipendent of response of FindDirty. I tried also to returns always an empty array from FindDirty, and still that table is persisted, obviuosly any other change isn't persisted.

The class is:
<class name="TaxonomyClass" table="CLASS" lazy="true">
<id name="Code">
<column name="CLASS_CODE"/>
<generator class="assigned" />
</id>
<property name="Name" />
<property name="Description" />
<many-to-one name="OwnerTaxonomyDomain" column="TAXONOMYDOMAIN" class="Taxonomy" cascade="none"/>
<many-to-one name="ClassParent" column="PARENT" class="TaxonomyClass" cascade="none"/>
<bag name ="ListSampleDoc" cascade="all" lazy="true" inverse="true" fetch="select">
<key column="CLASS"/>
<one-to-many class="SampleDocument"/>
</bag>
<bag name ="ListOwnerTaxonomyClassifiers" table="CLASSIFIERCLASSES" cascade="none" lazy="true" >
<key column="CLASS"/>
<many-to-many class="Taxonomy" column="TAXONOMYCLASSIFIER" not-found="ignore"/>
</bag>
<!--<bag name ="ListChild" cascade="all-delete-orphan" lazy="false">
<key column="PARENT"/>
<one-to-many class="TaxonomyClass"/>
</bag>-->
</class>

In bold the definition of relationship table.
FindDirty is:
public override int[] FindDirty(object entity, object id, object[] currentState, object[] previousState, string[] propertyNames, IType[] types)
{
int[] iRet = null;
/*if (SessionManager.EntityToSave == null ||
entity == SessionManager.EntityToSave ||
(bool)ArianeReflection.Invoke(entity, "IsInWeb", new object[]{SessionManager.EntityToSave}))
iRet = base.FindDirty(entity, id, currentState, previousState, propertyNames, types);
else*/
iRet = new int[] { };
return iRet;
}
