Problems with Session and transaction handling?

Read this: http://hibernate.org/42.html

I have been really strugging with some thing for the last couple of days
This is what I want to achieve
Person has a bank account has one contact
Contact has many phones many addresses etc
so when I set bankaccount to null I want the contact tree to disappear
this isn't happening I don;t know how to do thi
I first modelled bank account as a composite element then made it an entity as well.. but does not seem to cut it


<class name="BankAccount" table="BankAccount" lazy="true">
<id name="id" type="integer" column="id">
<generator class="native"/>
</id>

<property name="accountName">
<column name="Account_Name"/>
</property>
<property name="branch">
<column name="Branch"/>
</property>
<property name="accountNumber">
<column name="Account_Number"/>
</property>
<property name="bsb">
<column name="BSB"/>
</property>
<property name="bankName">
<column name="BankName"/>
</property>

<many-to-one name="bankContact" column="Contact_Id" unique="true" class="com.tramada.contact.model.Contact" cascade="all"/>


and I have in person a bag of bankaccounts
now when i set the bankaccount to be null i.e I delete the bank account reasonable expectation contact should disappear as well but only bank account disappears and not contact
Really struggling with this and I feel like breaking my head against a wall
I don't seem to see teh same thing in the test cases of hiberante

Can anyone help....
Can anyone help me..........

In your person class, set the cascade to be all-delete-orphan for the bankcontact mapping. That way, if you remove the Bankaccount from the person, it should cascade down to the bankcontacts. Check Section 21.3. Cascading lifecycle from the Ref docs for similar info.

Thanks for your reply but I already have a cascade all there that covers scade delete all orphans as well... That did not work

Cascade "all" is not the same as cascade "all-delete-orphan" i.e. "all" does not include orphan delete.

thanks for that I read the specs a little bit more carefully
A collection with cascade="all-delete-orphan" was no longer referenced by the owning entity instance

Get a runtime exception though when I do add that ...Let me debug it a bit more
