    <p>I can't get the selected item from a SelectOneMenu. I supply an ArrayList to the menu and want the user to select one of it. I put the menu into a form, so I have a commandButton which I intended to use to perform the selection. This implementation gives me this error : Cannot convert user3 of type class java.lang.String to class java.util.ArrayList when I select from the menu "user3", so it actually performs the selection correctly. The error refers to this line</p> <pre><code>&lt;h:selectOneMenu value="#{user.myUsers}" </code></pre> <p>Here is the part of my xhtml which generates the selectOneMenu.</p> <pre><code> &lt;h:panelGrid columns="3"&gt; &lt;h:form&gt; &lt;h:selectOneMenu value="#{user.myUsers}"&gt; &lt;f:selectItems value="#{user.myUsers }"/&gt; &lt;/h:selectOneMenu&gt; &lt;h:commandButton value="#{msgs.remove_user}" action="#{user.select }" &gt;&lt;/h:commandButton&gt; &lt;/h:form&gt; &lt;h:outputText value="#{ user.select}"&gt;&lt;/h:outputText&gt; &lt;/h:panelGrid&gt; </code></pre> <p>And here is my UserBean:</p> <pre><code> @ManagedBean(name="user") @SessionScoped public class UserBean implements Serializable { private String selected; public ArrayList&lt;String&gt; getMyUsers()throws Exception { ArrayList&lt;String&gt; ret; MySQLConnection conn = new MySQLConnection(); try{ ret = conn.getMyUsers(name); }finally { conn.closeConnection(); } return ret; } public String getSelect() throws Exception { if (this.selected==null) return this.getMyUsers().get(0); return this.selected; } public void setSelect(String s) { this.selected = s; } } </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.
