    <p>I have a JSP, which calls an action using the <code>&lt;s:action&gt;</code> tag:</p> <pre><code>&lt;s:form&gt; &lt;s:action name="myaction" namespace="/utente/include" executeResult="true" ignoreContextParams="true" var="formattazione" /&gt; //do something &lt;/s:form&gt; </code></pre> <p>The action <code>myaction</code> is called, i can follow the flow debugging it. It finishes fine without error, it returns success, but then there is an error and i can't understand which one.</p> <p>The action definition:</p> <pre><code>&lt;package name="utente-include" namespace="/utente/include" extends="tiles-default"&gt; &lt;action name="myaction" class="com.emaborsa.doctracing.web.action.formattazione.FormattazioneCriteriUtenteAction" method="formattazione"&gt; &lt;result type="tiles"&gt;mytiles.def&lt;/result&gt; &lt;/action&gt; &lt;/package&gt; </code></pre> <p>The tiles definition:</p> <pre><code>&lt;definition name="mytiles.def" template="/pages/empty.jsp"&gt; &lt;put-attribute name="body" value="/pages/mypage.jsp"/&gt; &lt;/definition&gt; </code></pre> <p>The empty.jsp:</p> <pre><code>&lt;%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%&gt; &lt;%@ taglib uri="http://tiles.apache.org/tags-tiles" prefix="tiles" %&gt; &lt;tiles:insertAttribute name="body" /&gt; </code></pre> <p>The Exception:</p> <pre><code>GRAVE: Servlet.service() for servlet jsp threw exception java.lang.NullPointerException at org.apache.struts2.views.jsp.ComponentTagSupport.doStartTag(ComponentTagSupport.java:49) at org.apache.jsp.pages.utente.elencoUtenti_jsp._jspx_meth_s_005fif_005f0(elencoUtenti_jsp.java:215) at org.apache.jsp.pages.utente.elencoUtenti_jsp._jspx_meth_s_005fform_005f0(elencoUtenti_jsp.java:155) at org.apache.jsp.pages.utente.elencoUtenti_jsp._jspService(elencoUtenti_jsp.java:87) at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:70) ..... </code></pre> <p>EDIT: i thought it works, but it doesn't. Actually the system doesn't crash, but the tiles-page is not included in the mail page. The Exception i get:</p> <pre><code>org.apache.tiles.impl.CannotRenderException: No request dispatcher returned for path '/../pages/common/myPage.jsp' at org.apache.tiles.impl.BasicTilesContainer.render(BasicTilesContainer.java:680) at org.apache.tiles.impl.BasicTilesContainer.render(BasicTilesContainer.java:633) at org.apache.tiles.impl.BasicTilesContainer.render(BasicTilesContainer.java:322) at org.apache.struts2.views.tiles.TilesResult.doExecute(TilesResult.java:105) at org.apache.struts2.dispatcher.StrutsResultSupport.execute(StrutsResultSupport.java:186) at com.opensymphony.xwork2.DefaultActionInvocation.executeResult(DefaultActionInvocation.java:361) at com.opensymphony.xwork2.DefaultActionInvocation.invoke(DefaultActionInvocation.java:265) at com.opensymphony.xwork2.interceptor.DefaultWorkflowInterceptor.doIntercept(DefaultWorkflowInterceptor.java:163) at com.opensymphony.xwork2.interceptor.MethodFilterInterceptor.intercept(MethodFilterInterceptor.java:87) at com.opensymphony.xwork2.DefaultActionInvocation.invoke(DefaultActionInvocation.java:236) </code></pre> <p>Here my myPage.jsp (actually it doesn't matter what is written in):</p> <pre><code>&lt;%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%&gt; &lt;%@ taglib prefix="s" uri="/struts-tags" %&gt; &lt;div class="navigazioneElenco" id="navigazioneElenco"&gt; &lt;/div&gt; </code></pre> <p>Here i share a part of my project.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
