    <p>I have the following controller</p> <pre><code> @Controller @RequestMapping("/project/view.html") public class ProjectViewController { private static final String viewName = "projectView"; @RequestMapping(method = RequestMethod.GET) public String showPage(Model model, @RequestParam(value="id",required=false) Long id) { //code..... return viewName; } } </code></pre> <p>My views.properties contains</p> <pre><code> projectView.(class)=org.springframework.web.servlet.view.JstlView projectView.url=/WEB-INF/jsp/project/view.jsp </code></pre> <p>Everything works as expected.</p> <p>But I needed to change the method to return a View(), cause I have to return a RedirectView() to some error page if something fails. So I've changed the method to:</p> <pre><code> @Controller @RequestMapping("/project/view.html") public class ProjectViewController { private static final String viewName = "projectView"; @RequestMapping(method = RequestMethod.GET) public View showPage(Model model, @RequestParam(value="id",required=false) Long id) { //code..... return new JstlView(viewName); } } </code></pre> <p>But in this case I get a NPE :</p> <pre><code> java.lang.NullPointerException at org.springframework.web.context.support.WebApplicationObjectSupport.getServletContext(WebApplicationObjectSupport.java:121) at org.springframework.web.servlet.view.JstlView.exposeHelpers(JstlView.java:133) at org.springframework.web.servlet.view.InternalResourceView.renderMergedOutputModel(InternalResourceView.java:209) at org.springframework.web.servlet.view.AbstractView.render(AbstractView.java:257) at org.springframework.web.servlet.DispatcherServlet.render(DispatcherServlet.java:1183) at org.springframework.web.servlet.DispatcherServlet.doDispatch(DispatcherServlet.java:902) at org.springframework.web.servlet.DispatcherServlet.doService(DispatcherServlet.java:807) at org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:571) at org.springframework.web.servlet.FrameworkServlet.doGet(FrameworkServlet.java:501) at javax.servlet.http.HttpServlet.service(HttpServlet.java:617) at javax.servlet.http.HttpServlet.service(HttpServlet.java:717) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at com.opensymphony.sitemesh.webapp.SiteMeshFilter.obtainContent(SiteMeshFilter.java:129) at com.opensymphony.sitemesh.webapp.SiteMeshFilter.doFilter(SiteMeshFilter.java:77) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:233) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:191) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:128) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:286) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:845) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:583) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:447) at java.lang.Thread.run(Thread.java:619) </code></pre> <p>I've debugged and it seems that getWebApplicationContext() returns null.</p> <p>Any help appreciated.</p> <p>Thanks.</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.

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).
