    <p>I have some problem with delation of associations, this is my code :</p> <blockquote> <p>Classe ModuleVersion</p> </blockquote> <pre><code>@ManyToMany(mappedBy="listModuleVersions") private List&lt;SuiteVersion&gt; suiteVersions = new ArrayList&lt;SuiteVersion&gt;(); </code></pre> <blockquote> <p>Classe SuiteVersion</p> </blockquote> <pre><code>@ManyToMany() private List&lt;ModuleVersion&gt; listModuleVersions = new ArrayList&lt;ModuleVersion&gt;();* </code></pre> <p>I would like to be able to delete automatically a suiteVersion or a moduleVersion with deletion of association. For example, if i delete a SuiteVersion with this code is delete automatically the association SuiteVersion to ModuleVersion. But if i delete a moduleVersion it doesn't automatically delete the association of SuiteVersion -> ModuleVersion. It is possible to do this automatically with ModuleVersion ?</p> <p><strong>Update</strong></p> <blockquote> <p>This is the action perform by hibernate if i delete a module with the adding of CASCADETYPE.REMOVE ...</p> </blockquote> <pre><code>Hibernate: delete from SUITE_VERSION_MODULE_VERSION where suiteVersions_ID_SUITE_VERSION=? Hibernate: delete from SUITE_VERSION_MODULE_VERSION where suiteVersions_ID_SUITE_VERSION=? Hibernate: delete from SUITE_VERSION_MODULE_VERSION where suiteVersions_ID_SUITE_VERSION=? Hibernate: delete from SUITE_VERSION_MODULE_VERSION where suiteVersions_ID_SUITE_VERSION=? Hibernate: delete from SUITE_VERSION_MODULE_VERSION where suiteVersions_ID_SUITE_VERSION=? //Hibernate: delete from SUITE_VERSION where ID_SUITE_VERSION=? //Hibernate: delete from SUITE_VERSION where ID_SUITE_VERSION=? Hibernate: delete from MODULE_VERSION where ID_MODULE_VERSION=? //Hibernate: delete from SUITE_VERSION where ID_SUITE_VERSION=? //Hibernate: delete from SUITE_VERSION where ID_SUITE_VERSION=? Hibernate: delete from MODULE_VERSION where ID_MODULE_VERSION=? //Hibernate: delete from SUITE_VERSION where ID_SUITE_VERSION=? Hibernate: delete from MODULE_VERSION where ID_MODULE_VERSION=? Hibernate: delete from MODULE where ID_MODULE=? </code></pre> <p>I just want the part none comitted to be executed. Thank you in advance for your help,</p> <p><strong>Update2</strong></p> <p>I tried to delete the module with this method implementation :</p> <pre><code> public static void removeModule(Module module) { for(ModuleVersion moduleVersion : module.getListModuleVersion()){ for(SuiteVersion suiteVersion : moduleVersion.getSuiteVersions()){ sessionFactory = HibernateFactory.getSessionFactory(); session = sessionFactory.getCurrentSession(); transaction = session.beginTransaction(); suiteVersion.removeFromModuleVersions(moduleVersion); transaction.commit(); } } sessionFactory = HibernateFactory.getSessionFactory(); session = sessionFactory.getCurrentSession(); session.delete(module); transaction.commit(); } </code></pre> <p>But i have this problem now : </p> <pre><code>Exception in thread "AWT-EventQueue-0" java.util.ConcurrentModificationException </code></pre> <p>Best regards,</p> <p>Florent.</p> <p>P.S: I'm french, sorry for my english.</p>

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.
