Text must not be null
Hi, we get sometimes a ‘Text must not be null’ exception from the HtmlResponseWriterImpl. We see the exception randomly. We now the xhtml file that triggers the error including the parameter the user has entered on the page. But we are not able to reproduce it on the server (you now – it works on my machine). Has anybody an idea? What is the reason for the error? How could we trace the error based on the stacktrace? Thanks Georg We use tomcat7 with myfaces 2.1.10 and tomahawk20 1.1.14. Here is the complete stacktrace: java.lang.NullPointerException: 'Text must not be null.' java.lang.NullPointerException: Text must not be null. at org.apache.myfaces.shared.renderkit.html.HtmlResponseWriterImpl.writeText(HtmlResponseWriterImpl.java:822) at org.apache.myfaces.shared.renderkit.html.HtmlRendererUtils.renderSelectOptions(HtmlRendererUtils.java:654) at org.apache.myfaces.shared.renderkit.html.HtmlSelectableRendererBase.internalRenderSelect(HtmlSelectableRendererBase.java:169) at org.apache.myfaces.shared.renderkit.html.HtmlMenuRendererBase.renderMenu(HtmlMenuRendererBase.java:91) at org.apache.myfaces.shared.renderkit.html.HtmlMenuRendererBase.encodeEnd(HtmlMenuRendererBase.java:76) at javax.faces.component.UIComponentBase.encodeEnd(UIComponentBase.java:665) at javax.faces.component.UIComponentBase.encodeAll(UIComponentBase.java:545) at org.apache.myfaces.shared.renderkit.RendererUtils.renderChildren(RendererUtils.java:693) at org.apache.myfaces.shared.renderkit.html.HtmlGroupRendererBase.encodeEnd(HtmlGroupRendererBase.java:115) at javax.faces.component.UIComponentBase.encodeEnd(UIComponentBase.java:665) at javax.faces.component.UIComponentBase.encodeAll(UIComponentBase.java:545) at javax.faces.component.UIComponentBase.encodeAll(UIComponentBase.java:541) at javax.faces.component.UIComponentBase.encodeAll(UIComponentBase.java:541) at org.apache.myfaces.renderkit.html.HtmlCompositeComponentRenderer.encodeEnd(HtmlCompositeComponentRenderer.java:71) at javax.faces.component.UIComponentBase.encodeEnd(UIComponentBase.java:665) at javax.faces.component.UIComponentBase.encodeAll(UIComponentBase.java:545) at javax.faces.component.UIComponentBase.encodeAll(UIComponentBase.java:541) at org.apache.myfaces.renderkit.html.HtmlCompositeComponentRenderer.encodeEnd(HtmlCompositeComponentRenderer.java:71) at javax.faces.component.UIComponentBase.encodeEnd(UIComponentBase.java:665) at javax.faces.component.UIComponentBase.encodeAll(UIComponentBase.java:545) at javax.faces.component.UIComponentBase.encodeAll(UIComponentBase.java:541) at javax.faces.component.UIComponentBase.encodeAll(UIComponentBase.java:541) at javax.faces.component.UIComponentBase.encodeAll(UIComponentBase.java:541) at org.apache.myfaces.renderkit.html.HtmlCompositeComponentRenderer.encodeEnd(HtmlCompositeComponentRenderer.java:71) at javax.faces.component.UIComponentBase.encodeEnd(UIComponentBase.java:665) at javax.faces.component.UIComponentBase.encodeAll(UIComponentBase.java:545) at javax.faces.component.UIComponentBase.encodeAll(UIComponentBase.java:541) at javax.faces.component.UIComponentBase.encodeAll(UIComponentBase.java:541) at org.apache.myfaces.view.facelets.FaceletViewDeclarationLanguage.renderView(FaceletViewDeclarationLanguage.java:1981) at org.apache.myfaces.application.ViewHandlerImpl.renderView(ViewHandlerImpl.java:285) at com.ocpsoft.pretty.faces.application.PrettyViewHandler.renderView(PrettyViewHandler.java:163) at javax.faces.application.ViewHandlerWrapper.renderView(ViewHandlerWrapper.java:59) at org.apache.myfaces.tomahawk.application.ResourceViewHandlerWrapper.renderView(ResourceViewHandlerWrapper.java:169) at org.apache.myfaces.lifecycle.RenderResponseExecutor.execute(RenderResponseExecutor.java:116) at org.apache.myfaces.lifecycle.LifecycleImpl.render(LifecycleImpl.java:241) at javax.faces.webapp.FacesServlet.service(FacesServlet.java:199) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:305) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:210) at com.tagwerk.webapp.utils.SessionTimeoutFilter.doFilter(SessionTimeoutFilter.java:110) at

I believe a label on a selectItem is null. 2013/5/15 Howard W.
