Hi guys
I have a model of that type
abstract class BaseEntity
{
Guid Id
}
class EntityA : BaseEntity
{
..other properties..
IList<EntityB> BEntities {get; set;}
}
class EntityB : BaseEntity
{
..other properties..
EntityA Owner {get, set;}
}
mapped as follow:
<class name="BaseEntity" abstract="true" table="TBL_BaseEntity"
dynamic-insert="true" dynamic-update="true" lazy="true" >
<id name="Id"
column="ID_ENTiTY"
type="guid"
unsaved-value="00000000-0000-0000-0000-000000000000">
<generator class="guid.comb" />
</id>
<discriminator column="EtityType" type="string" force="true" />
</class>
<subclass name="EntityA"
extends="BaseEntity"
discriminator-value="A"
dynamic-insert="true"
dynamic-update="true"
lazy="true">
<join table="TBL_ENTITYA">
<key column="ID_ENTITYA" />
...other mapped properties...
<bag name="BEntities" cascade="save-update"
lazy="true" inverse="true" fetch="select" outer-join="true" >
<key column="ID_ENTITYA" />
<one-to-many class="EntityB"/>
</bag>
</join>
</subclass>
<subclass name="EntityB"
extends="BaseEntity"
discriminator-value="B"
dynamic-insert="true"
dynamic-update="true"
lazy="true">
<join table="TBL_ENTITYB">
<key column="ID_ENTITYB" />
...other mapped properties...
<many-to-one name="Owner" not-null="true"
lazy="proxy" fetch="select" column="ID_ENTITYA" />
</join>
</subclass>
now the issue is when I try to insert and cascade a new EntityA with a
collection of EntityB correctly initialized (in terms of the bidirectional
association) everything works,
but when I try to read the EntityA.BEntities collection I got an exception
which states that NH could execute the query.
After whatching the issue with NHProf I saw that the query produced is
incorrect because NH append the column ID_ENTITYA to base table (which
clearly not has that column) and not to the
destination joined subclass table.
Anyone can help me about this prblem?
How can I avoid that behavior?
It's possible to do that in NH?
Thanks in advance.
