    <p>I have found some similar questions like <a href="https://stackoverflow.com/questions/2370489/creating-dynamic-controls-in-jsf-managed-bean">this</a> one, however there are so many ways this can be done that it made me more confused.</p> <p>We are getting an <code>XML</code> file that we are reading. This <code>XML</code> contains information on some form fields that needs to be presented. </p> <p>So I created this custom <code>DynamicField.java</code> that has all the information we need:</p> <pre><code>public class DynamicField { private String label; // label of the field private String fieldKey; // some key to identify the field private String fieldValue; // the value of field private String type; // can be input,radio,selectbox etc // Getters + setters. } </code></pre> <p>So we have a <code>List&lt;DynamicField&gt;</code>.</p> <p>I want to iterate through this list and populate the form fields so it looks something like this:</p> <pre><code>&lt;h:dataTable value="#{dynamicFields}" var="field"&gt; &lt;my:someCustomComponent value="#{field}" /&gt; &lt;/h:dataTable&gt; </code></pre> <p>The <code>&lt;my:someCustomComponent&gt;</code> would then return the appropriate JSF form components (i.e. label, inputText)</p> <p>Another approach would be to just display the <code>&lt;my:someCustomComponent&gt;</code> and then that would return an <code>HtmlDataTable</code> with form elements. (I think this is maybe easier to do).</p> <p>Which approach is best? Can someone show me to some links or code where it shows how I can create this? I prefer complete code examples, and not answers like "You need a subclass of <code>javax.faces.component.UIComponent</code>".</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.
