    <p>I have a problem with the deserialization with XStream (from a XML to a java object).</p> <p>The deserialization works well, except for the repeatable elements (which must turn into a List)...</p> <p>My XML :</p> <pre><code>&lt;DATA&gt; &lt;ANNUAIRES&gt; &lt;REC_ANNUAIRE&gt; &lt;NOPERS&gt;1815985&lt;/NOPERS&gt; &lt;NOM&gt;Dubois A. (Evilard)&lt;/NOM&gt; &lt;LIGNEADR1&gt;DUBOIS A.&lt;/LIGNEADR1&gt; &lt;/REC_ANNUAIRE&gt; &lt;REC_ANNUAIRE&gt; &lt;NOPERS&gt;0229984&lt;/NOPERS&gt; &lt;NOM&gt;Dubois Abel (La Chaux-de-Fonds)&lt;/NOM&gt; &lt;LIGNEADR1&gt;DUBOIS ABEL&lt;/LIGNEADR1&gt; &lt;/REC_ANNUAIRE&gt; &lt;REC_ANNUAIRE&gt; &lt;NOPERS&gt;0013717&lt;/NOPERS&gt; &lt;NOM&gt;Dubois Achim (Corpataux-Magnedens)&lt;/NOM&gt; &lt;LIGNEADR1&gt;DUBOIS ACHIM&lt;/LIGNEADR1&gt; &lt;/REC_ANNUAIRE&gt; &lt;REC_ANNUAIRE&gt; &lt;NOPERS&gt;1602681&lt;/NOPERS&gt; &lt;NOM&gt;Dubois Adrienne (Orvin)&lt;/NOM&gt; &lt;LIGNEADR1&gt;DUBOIS ADRIENNE&lt;/LIGNEADR1&gt; &lt;/REC_ANNUAIRE&gt; &lt;REC_ANNUAIRE&gt; &lt;NOPERS&gt;0384177&lt;/NOPERS&gt; &lt;NOM&gt;Dubois Agnes (Thun 7)&lt;/NOM&gt; &lt;LIGNEADR1&gt;DUBOIS AGNES&lt;/LIGNEADR1&gt; &lt;/REC_ANNUAIRE&gt; &lt;REC_ANNUAIRE&gt; &lt;NOPERS&gt;1424276&lt;/NOPERS&gt; &lt;NOM&gt;Dubois Agnes (Bussigny-Lausanne)&lt;/NOM&gt; &lt;LIGNEADR1&gt;DUBOIS AGNES&lt;/LIGNEADR1&gt; &lt;/REC_ANNUAIRE&gt; &lt;NBREC EOF="False"&gt;50&lt;/NBREC&gt; &lt;DUREE_EXECSQL&gt;0&lt;/DUREE_EXECSQL&gt; &lt;DUREE_BUILDXML&gt;0&lt;/DUREE_BUILDXML&gt; &lt;/ANNUAIRES&gt; &lt;/DATA&gt; </code></pre> <p>My XStream Code :</p> <pre><code>XStream xs = new XStream(); xs.alias("DATA", PojoPersonne.class); xs.alias("REC_ANNUAIRE", Personne.class); xs.aliasField("ANNUAIRES", PojoPersonne.class, "annuaire"); xs.aliasField("NOPERS", Personne.class, "idPersonne"); xs.aliasField("NOM", Personne.class, "identite"); xs.aliasField("STATUS", PojoPersonne.class, "status"); xs.addImplicitCollection(PojoPersonne.class, "listePersonne"); PojoPersonne pojo = (PojoPersonne)xs.fromXML(xml); System.out.println(pojo); pojo.afficheListe(); </code></pre> <p>My PojoPersonne class : </p> <pre><code>public class PojoPersonne { private String annuaire; private List&lt;Personne&gt; listePersonne = new ArrayList&lt;&gt;(); private String status; public PojoPersonne(String annuaire, ArrayList&lt;Personne&gt; listePersonne, String status){ this.annuaire = annuaire; this.listePersonne = listePersonne; this.status = status; } public PojoPersonne(){ this.listePersonne = new ArrayList&lt;&gt;(); } } </code></pre> <p>So the problem is from the listePersonne ArrayList... it's always null (or empty if I use <code>XStream xs = new XStream(new PureJavaReflectionProvider());</code>)</p> <p>Thanks for your help</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.

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).
