    <p>I'm familiar with RichFaces, but relatively new to Primefaces and trying to implement a simple <code>h:graphicImage</code> inside a <code>p:dataTable</code> (additionally inside a <code>ui:repeat</code>). This is the subsequent question of <a href="https://stackoverflow.com/questions/7307407">p:ajax inside h:graphicImage</a>. </p> <p>I will split the following <code>xhtml</code>-code to directly comment the behavior:</p> <pre><code>&lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"&gt; &lt;html xmlns="http://www.w3.org/1999/xhtml" xmlns:f="http://java.sun.com/jsf/core" xmlns:h="http://java.sun.com/jsf/html" xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:p="http://primefaces.prime.com.tr/ui" xml:lang="en" lang="en"&gt; &lt;h:head id="head"&gt; &lt;meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /&gt; &lt;title&gt;Test&lt;/title&gt; &lt;/h:head&gt; &lt;h:body id="body"&gt; &lt;f:view contentType="text/html"&gt; </code></pre> <p>Now the first <code>h:form</code> follows which contains a <code>h:outputText</code> and a <code>h:graphicImage</code>. By clicking on the image the bean method is called and the <em>counter</em> is correctly updated.</p> <pre><code>&lt;h:form id="f1"&gt; &lt;h:outputText id="counter" value="#{clientBean.counter}" /&gt; &lt;h:graphicImage url="/images/circle-ok.png"&gt; &lt;p:ajax event="click" update="counter" process="@this" listener="#{clientBean.tag}"/&gt; &lt;/h:graphicImage&gt; &lt;/h:form&gt;&lt;hr/&gt; </code></pre> <p>In the second <code>h:form</code> the button is inside a <code>p:dataTable</code>. If I click on the image, the bean method is called the counter is updated. (<strong>Note</strong> At firt I've tried to <code>update="counter"</code> without success)</p> <pre><code>&lt;h:form id="f2"&gt; &lt;p:dataTable var="var" value="#{clientBean.vf}"&gt; &lt;p:column&gt; &lt;f:facet name="header"&gt;Tag&lt;/f:facet&gt; &lt;h:graphicImage url="/images/circle-ok.png"&gt; &lt;p:ajax event="click" update="f1:counter" process="@this" listener="#{clientBean.tag}" /&gt; &lt;/h:graphicImage&gt; &lt;/p:column&gt; &lt;/p:dataTable&gt; &lt;/h:form&gt;&lt;hr/&gt; </code></pre> <p>The image inside <code>ui:repeated</code> updates the <em>counter</em> as expected:</p> <pre><code>&lt;ui:repeat var="var1" value="#{clientBean.list}"&gt; &lt;h:form id="f3"&gt; &lt;h:graphicImage url="/images/circle-ok.png"&gt; &lt;p:ajax event="click" update="f1:counter" process="@this" listener="#{clientBean.tag}" /&gt; &lt;/h:graphicImage&gt; </code></pre> <p>Now lets come to the <code>p:dataTable</code> inside a <code>ui:repeat</code>. With this piece of code the bean method is <strong>not</strong> called:</p> <pre><code> &lt;p:dataTable var="var2" value="#{var1.list}"&gt; &lt;p:column&gt; &lt;f:facet name="header"&gt;Tag&lt;/f:facet&gt; &lt;h:graphicImage url="/images/circle-ok.png"&gt; &lt;p:ajax event="click" update="f1:counter" process="@this" listener="#{clientBean.tag}" /&gt; &lt;/h:graphicImage&gt; &lt;/p:column&gt; &lt;/p:dataTable&gt; &lt;/h:form&gt; &lt;/ui:repeat&gt; &lt;/f:view&gt;&lt;/h:body&gt;&lt;/html&gt; </code></pre> <p>In this case I get the <code>&lt;partial-response&gt;&lt;changes&gt;&lt;update id="f1:counter"&gt;...</code>, but the bean method is not called (an inside it's <code>tag()</code>method the <em>counter</em> not updated). This is tested with a debug. I've read <a href="https://stackoverflow.com/questions/6856367/unable-to-use-pajax-on-my-primefaces-datatable">unable to use &lt;p:ajax&gt; on my primeface&#39;s datatable</a> but I have the same behaivour with <code>primefaces-3.0.M3.jar</code> and <code>primefaces-2.2.1.jar</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.
