Hello, i've been struggling to resolve the issue regarding object
insertion into IList<T> with index under NHibernate 2.0.
I have the following POCO and mapping file as Parent and Child
objects.
- Parent's POCO
public class Parent
{
public virtual decimal Id { get; set;}
......
public virtual IList<Child> Children { get; set;}
}
- Child's POCO
public vlass Child
{
public virtual decimal Id { get; set;}
public virtual Parent { get; set;}
public virtual string PropertyId { get; set;}
public virtual string PropertyValue { get; set;}
}
- Parent's mapping file
<class name="Parent" table="parents">
<id name="Id">
<generator class="native">
<param name="sequence">sq_parent</param>
</generator>
</id>
<list name="Children" cascade="all">
<key column="parent_id"/>
<index column="child_index"/>
<one-to-many class="Child"/>
</list>
</class>
- Child's mapping file
<class name="Child" table="children">
<id name="Id">
<generator class="native">
<param name="sequence">sq_child</param>
</generator>
</id>
<many-to-one name="Parent" class="Parent" column="parent_id" not-
null="true"/>
<property name="PropertyId" column="property_id"/>
<property name="PropertyValue" column="property_value"/>
</class>
Calling Parent.Children.Add(new Child(){...}) I've succeeded to update
Parent object which has already had some children objects..
But with Parent.Children.Insert(int, new Child(){})
ArgumentOutOfRangeException has been occured in transaction.Commit().
As a reference the following is stack trace (the mean showd in the
stack trace is "where the exception is occured").

場所 C:\Documents and Settings\hoge\My Documents\Visual Studio

Why has this exception been only thrown in case of IList<T>.Insert()
and why not in IList<T>.Add() ?
If you have any ideas, please let me know.
Regards.
