I've many-to-one and one-to-one properties in a proxied class and all my property and methods are virtual...when I load the object, NHibernate still loads the one-to-one property but not the many-to-ones? I think it's a bug in NHibernate because when I change the mapping of one-to-one to many-to-one, then none of the many-to-one are loaded. Below are my mapping files:

Code:
<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.0">
   <class name="WaterTrax.WTX.WTXObjectModel.DWFacSiteMsrmt, WTXObjectModel"
      table="tDWFacSiteMsrmts" proxy="WaterTrax.WTX.WTXObjectModel.DWFacSiteMsrmt, WTXObjectModel">   
      <id name="id" column="DWMsrmtID">
         <generator class="native" />
      </id>

      <one-to-one name="criteria" class="WaterTrax.WTX.WTXObjectModel.MeasurementWithCriteria, WTXObjectModel" />
      
      <many-to-one name="dwFacSite"
         class="WaterTrax.WTX.WTXObjectModel.DWFacSite, WTXObjectModel"
            column="DWFacSiteID"/>
      <property name="alertTypeID" column="AlertTypeID"/>
      
      <set name="msrmtPresenceAlerts" inverse="true" lazy="true">
         <key column="DWFacSiteMsrmtID"/>
         <one-to-many class="WaterTrax.WTX.WTXObjectModel.MsrmtPresenceAlert, WTXObjectModel"/>
      </set>   
...                   
   </class>
</hibernate-mapping>


Code:
<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.0">
   <class name="WaterTrax.WTX.WTXObjectModel.MeasurementWithCriteria, WTXObjectModel"
      table="vw_MeasurementWithCriteria" proxy="WaterTrax.WTX.WTXObjectModel.MeasurementWithCriteria, WTXObjectModel" mutable="false">
      <id name="id" column="DWMsrmtID" unsaved-value="0">
         <generator class="native" />
      </id>   
      <one-to-one name="msrmt" class="WaterTrax.WTX.WTXObjectModel.DWFacSiteMsrmt, WTXObjectModel" />
      <property name="type" column="ComparisonLevelLabel" />
      <property name="minVal" column="ReportComparisonMinValue" type="Nullables.NHibernate.NullableDoubleType, Nullables.NHibernate"/>
      <property name="maxVal" column="ReportComparisonMaxValue" type="Nullables.NHibernate.NullableDoubleType, Nullables.NHibernate"/>
      <property name="minDecimals" column="ReportComparisonMinDecimals"/>
      <property name="maxDecimals" column="ReportComparisonMaxDecimals"/>
      <many-to-one name="unit"
         class="WaterTrax.WTX.WTXObjectModel.Unit, WTXObjectModel"
         column="ReportComparisonUnitsID"/>
...   
   </class>
</hibernate-mapping>




Here's the log file, and notice that it's going to the DB to load:
