    <p>As said by Pete Muir, Seam lead developer</p> <blockquote> <p>Seam-gen does not support @ManyToMany relationship</p> </blockquote> <p>It does not generate the User Interface when using @ManyToMany. Although Seam-gen makes your life easier, sometimes, you have to do your job manually.</p> <p>Before going on</p> <ol> <li>Seam-gen uses Hibernate's reverse-engineering-tool</li> <li>If a foreign key <strong>is missing</strong> in the table, Seam-gen can not suppose one table is related to another</li> </ol> <p>...</p> <p>So my advice is: </p> <ol> <li>Split your @ManyToMany relationship into @OneToMany - @ManyToOne relationship</li> <li>Set up reverse-engineering configuration</li> </ol> <p>The reverse-engineering configuration file that Seam-gen uses is resources/seam-gen.reveng.xml inside the generated project.</p> <p>Maybe you want to see</p> <p><a href="https://www.hibernate.org/hib_docs/tools/reference/en/html/reverseengineering.html" rel="nofollow noreferrer">Controlling reverse engineering</a></p> <p><a href="https://www.hibernate.org/383.html" rel="nofollow noreferrer">Reverse engineering support in database and drivers</a></p> <p><strong>Added to original answer</strong></p> <p>Seam uses Ant to generate your app. Its build.xml file is located in the &lt;SEAM_HOME&gt;/seam-gen/build.xml</p> <p>There, you will see a target called <strong>generate-ui</strong> as follows</p> <pre><code>&lt;target name="generate-ui" </code></pre> <p>It uses a Ant Tool called <a href="https://www.hibernate.org/hib_docs/tools/reference/en/html/ant.html#hbmtemplate" rel="nofollow noreferrer">hbmtemplate</a>. It is a Template based Engine in which <strong>can be controlled by a user provided template or class</strong>. So if you want a custom behavior, you should provide your own Freemarker template. In &lt;SEAM_HOME&gt;/seam-gen/view directory, you can see a lot of Template files (.flt extension)</p> <p>regards,</p>

    1. COCurrently, I have lots of working code which is using the ManyToMany relationship. Splitting the relationship might be the right workaround for this solution, but is there any way that I could get the existing @ManyToMany List<Role> to render in a pagination fashion. I would need a mechanism to somehow tie up this list on top of the EntityQuery framework in Seam (Note: I would like not to re-do the existing code as we have already spent some time getting this to work based on @ManyToMany relationship)

    3. CO@Arthur looking forward to your response (As I mentioned earlier, we have too much code based on the existing @ManyToMany relationships)

Querying!

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.

SQuiL has stopped working due to an internal error.

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