    <p>I am making composite component where i have commandButton. But it doesn't work. </p> <p>Usage:</p> <pre><code>&lt;wk:commandButton value="Non-Ajax actionListener" actionListener="#{ioBean.saveListener}" /&gt; </code></pre> <p>Code of component: commandButton.xhtml</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;!DOCTYPE html&gt; &lt;html xmlns="http://www.w3.org/1999/xhtml" xmlns:c="http://java.sun.com/jsp/jstl/core" xmlns:f="http://java.sun.com/jsf/core" xmlns:p="http://primefaces.org/ui" xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:h="http://java.sun.com/jsf/html" xmlns:cc="http://java.sun.com/jsf/composite"&gt; &lt;cc:interface&gt; &lt;cc:attribute name="value" /&gt; &lt;cc:attribute name="action" method-signature="void action(javax.faces.event.ActionEvent)" default="null"/&gt; &lt;cc:attribute name="actionListener" method-signature="void actionListener(javax.faces.event.ActionEvent)" default="null"/&gt; &lt;cc:attribute name="styleClass" default="button" /&gt; &lt;/cc:interface&gt; &lt;cc:implementation&gt; &lt;p:commandButton value="#{cc.attrs.value}" action="#{cc.attrs.action}" actionListener="#{cc.attrs.actionListener}" styleClass="#{styleClass}"&gt; &lt;cc:insertChildren /&gt; &lt;/p:commandButton&gt; &lt;/cc:implementation&gt; &lt;/html&gt; </code></pre> <p>And this is log:</p> <pre><code>0000006c FaceletViewDe E Inner component action not found when retargetMethodExpressions 0000006c FaceletViewDe E Inner component actionListener not found when retargetMethodExpressions 0000006c srt W com.ibm.ws.webcontainer.srt.SRTServletResponse setIntHeader SRVE8094W: Ostrzeżenie: nie można ustawić nagłówka. Odpowiedź została już zatwierdzona. </code></pre> <p>I think the problem is with default value for action and actionListener. But according to the PrimeFaces documentation, default value for action and actionListener is null. One option is to make four different variants where action and actionListener are null or are defined but it doedn't seem to be good solution.</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.
