Any solutions for: “Found two representations of same collection" error.

Thanks !

post your hibernate mapping file(.xml) and code between session..

I am getting the below error:
“Error while saving customer: Found two representations of same collection: com.core.model.impl.ContactInfoImpl.contactTypeDetails”

[classes are: ContactInfo and ContactInfoDetails]

code from hbm files:

In Parent class:
<hibernate-mapping package="com.beacon.core.model.impl" default-lazy="true" default-cascade="all-delete-orphan">
<class name="ContactInfoImpl" table="CONTACT_INFO">

<bag name="contactTypeDetails" inverse="true">
<key column="CONTACT_INFO_ID"/>
<one-to-many class="ContactTypeDetailImpl"/>
</bag>
</class>
<query name="com.core.model.impl.ContactInfoImpl.select.all">
<![CDATA[
from com.core.model.impl.ContactInfoImpl as entity
]]>
</query>


and the child class:
<hibernate-mapping package="com.core.model.impl" default-lazy="true" default-cascade="all-delete-orphan">
<class name="ContactTypeDetailImpl" table="CONTACT_TYPE_DETAIL" >

<many-to-one
name="contactInfo"
column="CONTACT_INFO_ID"
class="ContactInfoImpl"
not-null="false"
/>

<query name="com.core.model.impl.ContactTypeDetailImpl.select.all">
<![CDATA[
from com.core.model.impl.ContactTypeDetailImpl as entity
]]>
</query>

we weren’t doing manual session management ! Looks like it is a cascase issue with reference to another post: http://www.damnhandy.com/2008/08/20/hib ... ion-error/

But the cascade in the mapping file is :default-cascade="all-delete-orphan"

Not sure which piece needs a fix?

Your help is very much appreciated !

additional information to the above post:

ContactInfo contains ContactTypeDetail
ContactTypeDetail contains PartyContactDetail
PartyContactDetail contains PartyDetail

PartyContactDetails hbm:

Hi

I assumed that this seems you are updating the collection after clearing the session.

there is workaround for this, you can find that in the same forum using below link

Good luck..

Thanks for the reply.

I will post the result, if I am able to resolve the issue ;)
