Hi,

I have just recovered an application wich use ZK 6.5.2.

When I start the application I have this error :

GRAVE: "Servlet.service()" pour la servlet zkLoader a généré une exception java.lang.NullPointerException at org.zkoss.bind.impl.MiscUtil.mergeExceptionInfo(MiscUtil.java:165) at org.zkoss.bind.BindComposer.initViewModel(BindComposer.java:246) at org.zkoss.bind.BindComposer.doBeforeComposeChildren(BindComposer.java:141) at org.zkoss.zk.ui.impl.UiEngineImpl.doBeforeComposeChildren(UiEngineImpl.java:882) at org.zkoss.zk.ui.impl.UiEngineImpl.execCreateChild0(UiEngineImpl.java:821) at org.zkoss.zk.ui.impl.UiEngineImpl.execCreateChild(UiEngineImpl.java:778) at org.zkoss.zk.ui.impl.UiEngineImpl.execCreate0(UiEngineImpl.java:687) at org.zkoss.zk.ui.impl.UiEngineImpl.execCreateChild(UiEngineImpl.java:749) at org.zkoss.zk.ui.impl.UiEngineImpl.execCreate0(UiEngineImpl.java:709) at org.zkoss.zk.ui.impl.UiEngineImpl.execCreate(UiEngineImpl.java:651) at org.zkoss.zk.ui.impl.UiEngineImpl.execNewPage0(UiEngineImpl.java:401) at org.zkoss.zk.ui.impl.UiEngineImpl.execNewPage(UiEngineImpl.java:316) at org.zkoss.zk.ui.http.DHtmlLayoutServlet.process(DHtmlLayoutServlet.java:215) at org.zkoss.zk.ui.http.DHtmlLayoutServlet.doGet(DHtmlLayoutServlet.java:136) at javax.servlet.http.HttpServlet.service(HttpServlet.java:622) at javax.servlet.http.HttpServlet.service(HttpServlet.java:729) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:230) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:165) at org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter.java:52) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:192) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:165) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:198) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:108) at org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:472) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:140) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:79) at org.apache.catalina.valves.AbstractAccessLogValve.invoke(AbstractAccessLogValve.java:620) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:87) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:349) at org.apache.coyote.http11.Http11Processor.service(Http11Processor.java:784) at org.apache.coyote.AbstractProcessorLight.process(AbstractProcessorLight.java:66) at org.apache.coyote.AbstractProtocol$ConnectionHandler.process(AbstractProtocol.java:802) at org.apache.tomcat.util.net.NioEndpoint$SocketProcessor.doRun(NioEndpoint.java:1410) at org.apache.tomcat.util.net.SocketProcessorBase.run(SocketProcessorBase.java:49) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at org.apache.tomcat.util.threads.TaskThread$WrappingRunnable.run(TaskThread.java:61) at java.lang.Thread.run(Thread.java:745)

And despite a search I can not understand where this error can come from. I know that these lines of MiscUtil.java (a ZK class) throw the exception :

        String orgMsg = ex.getMessage();
        String msg = formatLocationMessage(null,location,showColumn);
        if(orgMsg.endsWith(msg)){

Because the value "orgMsg" is null.

This error occurs with this code in th .zul file :

<window border="none" height="100%" apply="org.zkoss.bind.BindComposer" viewmodel="@id('vm') @init('com.eurocopter.techpub.peps.controller.MainController')">

Anybody can help me ?

Thanks
