    <p>We have an Email object.</p> <p>The email.hbm has</p> <pre><code>&lt;bag name="emailRecipients" lazy="false" inverse="false" cascade="save-update" fetch="select"&gt; &lt;key column="EMAIL_ID" /&gt; &lt;one-to-many class="EmailRecipient" /&gt; &lt;/bag&gt; &lt;bag name="emailStateRecipients" lazy="false" inverse="false" cascade="save-update" fetch="select"&gt; &lt;key column="EMAIL_ID" /&gt; &lt;one-to-many class="EmailStateRecipient" /&gt; &lt;/bag&gt; </code></pre> <p>I'm trying to save a new email which has an arraylist of EmailRecipient &amp; EmailStateRecipient objects.</p> <p>When I tried:</p> <pre><code>this.getHibernateTemplate().saveOrUpdate(email); </code></pre> <p>Got an error:</p> <pre><code>org.springframework.orm.hibernate3.HibernateSystemException: a different object with the same identifier value was already associated with the session: [com.abc.model.EmailRecipient#0]; nested exception is org.hibernate.NonUniqueObjectException: a different object with the same identifier value was already associated with the session: [com.abc.model.EmailRecipient#0] </code></pre> <p>So i changed to:</p> <pre><code>this.getHibernateTemplate().merge(email); </code></pre> <p>Now get this error:</p> <pre><code>org.springframework.orm.hibernate3.HibernateObjectRetrievalFailureException: No row with the given identifier exists: [com.abc.model.EmailRecipient#0]; nested exception is org.hibernate.ObjectNotFoundException: No row with the given identifier exists: [com.abc.model.EmailRecipient#0] </code></pre> <p>Can somebody help on resolving this. I think I have to check if the object already exists &amp; if yes, then merge or else save. But not sure how. Also if the hbm correct?</p> <p>Thanks</p> <p><strong>Edit:</strong></p> <p>EmailRecipient.hbm</p> <pre><code>&lt;hibernate-mapping package="com.abc.model"&gt; &lt;class name="EmailRecipient" table="EMAIL_RCPNT"&gt; &lt;id name="emailRecipientId" column="EMAIL_RCPNT_ID" type="long"&gt; &lt;generator class="sequence"&gt; &lt;param name="sequence"&gt;SEQ_RCPNT_ID_PK&lt;/param&gt; &lt;/generator&gt; &lt;/id&gt; &lt;property name="roleId" column="ROLE_ID" type="long" /&gt; &lt;/class&gt; &lt;/hibernate-mapping&gt; </code></pre> <p>Have not added the emailId property to the Recipient.hbm as it is declared as OneToMany in the email.hbm.</p> <p>Another weird aspect is, this (saveOrUpdate) works fine on my unit test, but does not when running from the app.</p>

    1. COcom.abc.model.EmailRecipient#0 - #0 means it has an id of 0, which means it hasn't been saved yet. Can you post the full mapping file of EmailRecipient? I think the problem can be found there (probably wrong generator class)

    3. COYou need to merge element by yourself to the list. So if you have element 1 and you need to add element 1 don't add. Not sure if this suppose to solve, but try. I. Additional try to call clear and than add elementa

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
