I have created a mapping file like this.

<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" default-lazy="true">
<class name="AIMSObjects.EntityClasses.OrderHeader, AIMSObjects" table="orderHdr" optimistic-lock="version" dynamic-update="true" >
<id name="FrndOrder" column="`order`" unsaved-value="-1">
<generator class="assigned"></generator>
</id>
<!--Order line list one to many mapping on orderlines -->
<set name="OrderLines" table="orderln" lazy="true" inverse="true" cascade="all-delete-orphan" generic="true" access="field.camelcase-underscore">
<key column ="`ORDER`" foreign-key="`order`"></key>
<one-to-many class ="AIMSObjects.EntityClasses.OrderLine, AIMSObjects"/>
</set>
</class >
</hibernate-mapping >

while i am saving the entity as me.save(OrderEntity,Permission) it throughs the error " Found shared references to a collection in "AIMSObjects.EntityClasses.OrderHeader.orderlines"


Please provide me the solution for this.

my requirement is to copy an entity and create a new entity in the database with same values

i am doing as below

Dim objDistributionOrder As New OrderHeader
objDistributionOrder = objOrderHeader.Clone()
and after while saving data it give me the error
