Check the code you are using, sometimes in an attempt to obfuscate code data (like variable names, package names that could contain sensitive info), we omit or alter something related to the bug at hand.</p> <p>This is the code (ipsis literis) I used to test your example:</p> <p>SomeBean.java</p> <pre><code>import java.util.ArrayList; import java.util.List; import javax.faces.bean.ManagedBean; import javax.faces.bean.ViewScoped; @ManagedBean @ViewScoped public class SomeBean { private List&lt;SomeObjects&gt; data = new ArrayList&lt;SomeObjects&gt;(); public void addItem(){ data.add(new SomeObjects("someName")); } public List&lt;SomeObjects&gt; getData() { return data; } public void setData(List&lt;SomeObjects&gt; data) { this.data = data; } } </code></pre> <p>SomeObject.java</p> <pre><code>public class SomeObjects { private String name; public SomeObjects(String string) { this.setName(string); } public void setName(String name) { this.name = name; } public String getName() { return name; } } </code></pre> <p>draggable.xhtml</p> <pre><code>&lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"&gt; &lt;html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html" xmlns:f="http://java.sun.com/jsf/core" xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:p="http://primefaces.org/ui" xmlns:c="http://java.sun.com/jsp/jstl/core"&gt; &lt;h:head&gt; &lt;/h:head&gt; &lt;h:body&gt; &lt;p:separator styleClass="espacador" /&gt; &lt;p:fieldset legend="PreparedData"&gt; &lt;p:dataGrid id="currentData" columns="1" var="res" value="#{someBean.data}"&gt; &lt;p:column&gt; &lt;p:panel id="draggedres" header="#{res.name}"&gt; &lt;h:panelGrid columns="1"&gt; &lt;h:outputText value="#{res.name}" /&gt; &lt;/h:panelGrid&gt; &lt;/p:panel&gt; &lt;p:draggable for="draggedres" /&gt; &lt;/p:column&gt; &lt;/p:dataGrid&gt; &lt;/p:fieldset&gt; &lt;p:commandButton value="Add" actionListener="#{someBean.addItem}" update="currentData" /&gt; &lt;h:body&gt; &lt;/html&gt; </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.

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).
