Hi everybody,

I have a collection mapped to a column which is not the primary key.

The child class mapping :

Code:
<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" assembly="tsdmodel"
namespace="tsdmodel.engine.entity">
  <class name="EntityTimeLineRecord" table="EntityTimeLineRecord">
    <id name="Index" column="idx">
      <generator class="increment"/>
    </id>
    <property name="id" column="id" access="field" type="string"/>
    <property name="Day0" column="day0"/>
    <property name="Day1" column="day1"/>
    <property name="Day2" column="day2"/>
    <property name="Day3" column="day3"/>
    <property name="Day4" column="day4"/>
    <property name="Day5" column="day5"/>
    <property name="Day6" column="day6"/>
    <property name="Label" column="label"/>
    <property name="Start" column="start"/>
    <property name="Finish" column="finish"/>
    <property name="Week" column="week"/>
  </class>
</hibernate-mapping>


The parent class mapping :

Code:
<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" assembly="tsdmodel"
namespace="tsdmodel.engine.entity">
  <class name="Room" table="Room">
    <id name="id" column="rid" access="field">
      <generator class="increment">
      </generator>
    </id>
    <property name="Name" column="name"/>
    <many-to-one name="RoomType" column="rtid"/>
    <many-to-one name="Sector" column="scid"/>
    <property name="AcceptExams" column ="acceptexams"/>   
    <property name="Priority" column="priority"/>
    <property name="Size" column="size"/>
    <property name ="EntityId" column ="guid" type="String"/>
    <bag name="Records" cascade="all" collection-type="obpdlayer.coll.NHCustomCollection`1[[tsdmodel.engine.entity.EntityTimeLineRecord, tsdmodel]], obpdlayer">     
      <key column="id" property-ref="EntityId"/>           
      <one-to-many class="EntityTimeLineRecord"/>
    </bag>
  </class>


The problem is when I insert child records (EntityTimeLineRecords) it works perfectly bu when I try to load instances of type "Room" I got this exception :

Code:
NHibernate.Exceptions.GenericADOException: could not initialize a collection: [tsdmodel.engine.entity.Room.Records#511af0c164bf4253b0880a977610ad79][SQL: SELECT records0_.id as id1_, records0_.idx as idx1_, records0_.idx as idx73_0_, records0_.id as id73_0_, records0_.day0 as day3_73_0_, records0_.day1 as day4_73_0_, records0_.day2 as day5_73_0_, records0_.day3 as day6_73_0_, records0_.day4 as day7_73_0_, records0_.day5 as day8_73_0_, records0_.day6 as day9_73_0_, records0_.label as label73_0_, records0_.start as start73_0_, records0_.finish as finish73_0_, records0_.week as week73_0_ FROM EntityTimeLineRecord records0_ WHERE records0_.id=?] ---> System.ArgumentException: Identifier type mismatch; Found:<System.Int32> Expected:<System.String>
Nom du paramètre : identifier


Likely, it is trying to map an int32 property to a string parameter.

What's wrong with that ?

Best regards
