    <p>Hi suppose you have the following composite component:</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:ui="http://java.sun.com/jsf/facelets" xmlns:h="http://java.sun.com/jsf/html" xmlns:f="http://java.sun.com/jsf/core" xmlns:composite="http://java.sun.com/jsf/composite" &gt; &lt;composite:interface&gt; &lt;composite:attribute name="action" targets="#{cc.clientId}:value"/&gt; &lt;/composite:interface&gt; &lt;composite:implementation&gt; &lt;h1&gt;clientId is: #{cc.clientId}&lt;/h1&gt; &lt;h:commandButton id="value" action="null" value="submit"/&gt; &lt;/composite:implementation&gt; &lt;/html&gt; </code></pre> <p>This composite component simply prints out the <strong>clientId</strong> now if I use this composite component as follows:</p> <pre><code>&lt;h:form id="formID"&gt; &lt;wui:test id="testID"/&gt; &lt;/h:form&gt; </code></pre> <p>What I would expect to have as a result is:</p> <p><strong>clientId is: formID:testID</strong> </p> <p>BUT what I really get is: </p> <p><strong>clientId is: testID</strong></p> <p>Now if I click on the button the form will be submitted and now the result is:</p> <p><strong>clientId is: formID:testID</strong> </p> <p>What is causing the problem is the <strong>action</strong> attribute in the composite interface, if I remove it then the id is always <strong>formID::testID</strong></p> <p>Am I missing something?</p> <hr> <p><strong>Update:</strong></p> <p>I am using Mojarra <strong>javax.faces-2.1.4.jar</strong></p> <hr> <p><strong>Update:</strong></p> <p>I created an issue for the Mojarra team: <a href="http://java.net/jira/browse/JAVASERVERFACES-2278" rel="nofollow">http://java.net/jira/browse/JAVASERVERFACES-2278</a></p>

    1. COInteresting, I can reproduce this on Mojarra 2.1.4, but not in MyFaces 2.1.3. Even more, in MyFaces it's always `testID`. I'd also expect it to be `formID:testID` all the time, not sure why MyFaces is doing it differently. In any way, this is worth an issue report to the Mojarra guys.

    3. COGood you posted the issue. Note that the normal way would be using `targets="value"`. But that still don't solve the issue with `<h1>clientId is: #{cc.clientId}</h1>`.

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.
