I’m trying to update a object with one-one association, some thing like:
//User has one-one relation with Address, WebAddress is subclass of Address.
----------------------
//retrieve first
User user = bean.retrieveUser(id);

//update
user.setName(“Jon”);
WebAddress address = (WebAddress)user.getAddress();

address.setEmail(jonlL@citi.fin.com);
user.setAddress(address);
bean.updateUser(user);
-------------------------------
Update calls saveORUpdate API.
Retrieve works fine. On update (WebAddress table) it’s trying to create a new record instead of updating. UserID is PK in all 3 tables (USER, ADDRESS, WEBADDRESS).
Obviously INSERT fails because there is already record in database.
Some where ID’s/associations are disconnected.
On session.refresh(user.getAddress()) --> exception is "The class has no identifier property".
I would highly appreciate inputs.

Thanks in advance, R.

hi,

can you post real code and the corresponding mapping files?

rgds

Hi,
Thanks for looking into this issue.
I'm using same session (always current session).
It works for all other update graphs(collections), this use case is slightly different. We have same User.Id as PrimaryKey (Address.userId is PK & FK, WebAddress – userId is PK&FK), basically same ID identifies all (because it’s 1-1 relation).

Mapping files:

code:
--------------------------------------------------------------------------------

************* User*************
<hibernate-mapping> <class name="User" table="USER" lazy="false">
...............................................
<one-to-one name="address" class="Address" cascade="save-update,lock" lazy="no-proxy" access="field"/>
</class>
</hibernate-mapping>

--------------------------------------------------------------------------------

*************
Address.xml:

--------------------------------------------------------------------------------

<class name=" Address" table=" Address" lazy="false" discriminator-value=" Address">
<id column="USERID" type="string">
<generator class="foreign">
<param name="address">address</param>
</generator>
</id>
<discriminator column="CODE" type="string"/>
<one-to-one name="user" class="User" cascade="all" constrained="true"/>
</class>

--------------------------------------------------------------------------------


***********************
WebAddress.xml:
--------------------------------------------------------------------------------

<subclass name=" WebAddress " lazy="false" discriminator-value=" WebAddress" extends="Address">
<join table=" WebAddress">
<key><column name="USERID"/></key>
<property name="email" column="email" type="string" length="50" not-null="false" lazy="false"/>
</join>
</subclass>

--------------------------------------------------------------------------------

Note: Same code works if I do every thing in a single service method (retrieve, update, commit in the same current session & API). Not sure why it's disconnected on passing to client.
I'm using saveOrUpdate() API in my Bean.

I’m really stuck with this problem; I would appreciate your help!
Thanks, R.

hi,

-bit late here so i do quickly-
the objects are disconnected from the session.
Check documentation which describes these mechanisms (reattachment) and specifically section : 10.6. Modifying detached objects

rgds,

Thanks for your response.
I reviewed documentation, but re-attachment is not really working.
I'm getting exceptions like "there is another object with same identifier".
Only thing works:
delete old object, recreate from client input. This is ugly but it works.
I’m doing something like {create new session, load User, delete Address Association (WebAddress ), flush & close this session} , { invoke saveOrUpdate(User) in current active session.

I would really appreciate your valuable inputs.
-R.
