Simply put? RTFM... sorry for being mean and direct. Okay, so you are missing the markup (aka HTML file) with all the silly wicket:id tags. The missing tag as per your exception is a header 0 of some sort.
Post more code or tell us what you're trying to achieve if you want more help. Better yet, read the Wicket free guide off the home page for Wicket's project under the Books section,mi guess you are trying out some sort of repeater?!?!? In case you need the direct link: http://wicket.apache.org/learn/books/freeguide.html Have a great day, Paul Bors PS: Again, sorry for being direct :) On Jul 7, 2013, at 9:57 PM, fan wang <xingfan_w...@live.cn> wrote: > when i close my browser and open the project again,then show the > Exception,what's wrong? thx!!! > > Last cause: Markup not found for Component: [HtmlHeaderContainer [Component > id = _header_0]] > > Stacktrace > > Root cause: > org.apache.wicket.markup.MarkupNotFoundException: Markup not found f > Component: [HtmlHeaderContainer [Component id = _header_0]] > at org.apache.wicket.Component.internalRender(Component.java:2333) > at org.apache.wicket.Component.render(Component.java:2293) > at > org.apache.wicket.MarkupContainer.renderNext(MarkupContainer.java:, 13 > at > org.apache.wicket.MarkupContainer.renderAll(MarkupContainer.java:1553) > at org.apache.wicket.Page.onRender(Page.java:884) > at org.apache.wicket.markup.html.WebPage.onRender(WebPage.java:142) > at org.apache.wicket.Component.internalRender(Component.java:2365) > at org.apache.wicket.Component.render(Component.java:2293) > at org.apache.wicket.Page.renderPage(Page.java:1021) > at > org.apache.wicket.request.handler.render.WebPageRenderer.renderPage(WebPageRenderer.java:116) > at > org.apache.wicket.request.handler.render.WebPageRenderer.respond(WebPageRenderer.java:244) > at > org.apache.wicket.core.request.handler.RenderPageRequestHandler.respond(RenderPageRequestHandler.java:165) > at > org.apache.wicket.request.cycle.RequestCycle$HandlerExecutor.respond(RequestCycle.java:830) > at > org.apache.wicket.request.RequestHandlerStack.execute(RequestHandlerStack.java:64) > at > org.apache.wicket.request.cycle.RequestCycle.execute(RequestCycle.java:253) > at > org.apache.wicket.request.cycle.RequestCycle.processRequest(RequestCycle.java:210) > at > org.apache.wicket.request.cycle.RequestCycle.processRequestAndDetach(RequestCycle.java:281) > at > org.apache.wicket.protocol.http.WicketFilter.processRequest(WicketFilter.java:188) > at > org.apache.wicket.protocol.http.WicketFilter.doFilter(WicketFilter.java:245) > at > org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) > at > org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) > at > org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:233) > at > org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:191) > at > org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) > at > org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:103) > at > org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) > at > org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:293) > at > org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:861) > at > org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:606) > at > org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:489) > at java.lang.Thread.run(Thread.java:722) > > > > > > > > -- > View this message in context: > http://apache-wicket.1842946.n4.nabble.com/how-to-solve-this-problem-tp4660122.html > Sent from the Users forum mailing list archive at Nabble.com. > > --------------------------------------------------------------------- > To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org > For additional commands, e-mail: users-h...@wicket.apache.org >
