    <p>When creating a new item the user does not want to see the null no selection option in the Select-One Menu, but directly an item from the available items. So either to get rid of the null no option or display directly the second element in the dropdown. I tried the attribute <code>hideNoSelection</code>, but it does nothing. How can I achieve this?</p> <pre><code>&lt;h:selectOneMenu id="ugroup" value="#{usersController.selected.ugroup}" title="#{bundle.CreateUsersTitle_ugroup}" required="true" requiredMessage="#{bundle.CreateUsersRequiredMessage_ugroup}"&gt; </code></pre> <p></p> <pre><code>&lt;/h:selectOneMenu&gt; </code></pre> <p>----------------EDIT (after @Balus Answer) --------------------- Here is the Utility method that grabs JPA Lists to be displayed as a <code>&lt;h:selectOneMenu /&gt;</code> :</p> <pre><code>public class JsfUtil { public static SelectItem[] getSelectItems(List&lt;?&gt; entities, boolean selectOne) { int size = selectOne ? entities.size() + 1 : entities.size(); SelectItem[] items = new SelectItem[size]; int i = 0; if (selectOne) { // part to be removed items[0] = new SelectItem("", "---"); i++; } // end of part to be removed for (Object x : entities) { items[i++] = new SelectItem(x, x.toString()); } return items; } </code></pre> <p>So appearently, all I have to do is remove this part? :</p> <pre><code> if (selectOne) { items[0] = new SelectItem("", "---"); i++; } </code></pre> <p>But as this static method is used everywhere in my code, would it have any unwanted consequences?</p> <ul> <li><p>Like, when the user wants explicitly a null value from the <strong><code>&lt;h:selectOneMenu /&gt;</code></strong>, if he decides to choose no option. My guess was to use <strong><code>&lt;f:selectItem</code></strong> :</p> <p> </p> <p> </p></li> </ul>

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.
