    <p>I'm new to Hibernate and am trying to save a "UserState" with a list of "WorkspaceState"s. UserState objects are keyed by a username that is set, the WorkspaceStates are set by UUID scheme. My issue is that if I have a UserState with one WorkspaceState in it, the UserState gets saved but the WorkspaceState does not.</p> <p>Here are the Hibernate mapping</p> <pre><code>&lt;hibernate-mapping&gt; &lt;class name="UserState" table="USERSTATE"&gt; &lt;id name="owner" type="java.lang.String"&gt; &lt;column name="OWNER" /&gt; &lt;generator class="assigned" /&gt; &lt;/id&gt; &lt;list name="workspaces" inverse="false" cascade="all" table="WORKSPACESTATE" lazy="true"&gt; &lt;key&gt; &lt;column name="UID" /&gt; &lt;/key&gt; &lt;list-index&gt;&lt;/list-index&gt; &lt;one-to-many class="WorkspaceState" /&gt; &lt;/list&gt; &lt;/class&gt; &lt;/hibernate-mapping&gt; &lt;hibernate-mapping&gt; &lt;class name="WorkspaceState" table="WORKSPACESTATE"&gt; &lt;id name="uid" type="java.lang.String"&gt; &lt;column name="UID" /&gt; &lt;generator class="uuid" /&gt; &lt;/id&gt; &lt;property name="owner" type="java.lang.String"&gt; &lt;column name="OWNER" /&gt; &lt;/property&gt; &lt;/class&gt; &lt;/hibernate-mapping&gt; </code></pre> <p>I have a UserState object with one WorkspaceState in it. When I do a session.saveOrUpdate(userst), I see that hibernate has already removed the WorkspaceState from my userst object. Then the commit saves it to the DB without the workspacestate in it.</p> <p>In truth the WorkspaceState themselves have lists, but I suspect whatever I'm doing wrong continues onward.</p> <p>Thanks</p> <p>Edit - how it's committed. HibernateUtil is as it appears in the standard hibernate document examples:</p> <pre><code>Session session = HibernateUtil.getSessionFactory().openSession(); Transaction transaction = null; try { transaction = session.beginTransaction(); String username = (String) session.merge(state); transaction.commit(); } catch (HibernateException e) { transaction.rollback(); e.printStackTrace(); return false; } finally { session.close(); } </code></pre>

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.
