Hi, I am having a problem with submit link. I used to have a form with a regular link on it but then the form data would not get submitted. Now I have replaced this by a SubmitLink and in my onSubmit() I do: validate(); updateFormComponentModels(); // Remove messages cause by validation. getPage().getFeedbackMessages().clear(); This is done to make sure all field values are available and that validation is suppressed. The problem (see below) also occurs when I don't execute the above statements in my onSubmit(). Now back button support is broken. The problem occurs when I click on a link to edit an item to a collection. The result of clicking a link for adding an item is that a new item is added to a list displayed on the screen with a SubmitLink next to it for deleting it. The problem occurs when I do the following:
WicketMessage: Attempt to access unknown request listener interface null Root cause: wicket.WicketRuntimeException: Attempt to access unknown request listener interface null at wicket.markup.html.form.Form.dispatchEvent(Form.java:1205) at wicket.markup.html.form.Form.onFormSubmitted(Form.java:293) at java.lang.reflect.Method.invoke(Method.java:585) at wicket.RequestListenerInterface.invoke(RequestListenerInterface.java:163) at wicket.request.target.component.listener.ListenerInterfaceRequestTarget.processEvents(ListenerInterfaceRequestTarget.java:74) at wicket.request.compound.DefaultEventProcessorStrategy.processEvents(DefaultEventProcessorStrategy.java:65) at wicket.request.compound.AbstractCompoundRequestCycleProcessor.processEvents(AbstractCompoundRequestCycleProcessor.java:57) at wicket.RequestCycle.doProcessEventsAndRespond(RequestCycle.java:852) at wicket.RequestCycle.processEventsAndRespond(RequestCycle.java:885) at wicket.RequestCycle.step(RequestCycle.java:966) at wicket.RequestCycle.steps(RequestCycle.java:1040) at wicket.RequestCycle.request(RequestCycle.java:454) at wicket.protocol.http.WicketServlet.doGet(WicketServlet.java:216) at wicket.protocol.http.WicketServlet.doPost(WicketServlet.java:259) at javax.servlet.http.HttpServlet.service(HttpServlet.java:717) at javax.servlet.http.HttpServlet.service(HttpServlet.java:810) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:252) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) at org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:202) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:213) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:178) at org.jboss.web.tomcat.security.SecurityAssociationValve.invoke(SecurityAssociationValve.java:175) at org.jboss.web.tomcat.security.JaccContextValve.invoke(JaccContextValve.java:74) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:126) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:105) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:107) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:148) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:869) at org.apache.coyote.http11.Http11BaseProtocol$Http11ConnectionHandler.processConnection(Http11BaseProtocol.java:664) at org.apache.tomcat.util.net.PoolTcpEndpoint.processSocket(PoolTcpEndpoint.java:527) at org.apache.tomcat.util.net.MasterSlaveWorkerThread.run(MasterSlaveWorkerThread.java:112) at java.lang.Thread.run(Thread.java:595) This could be a problem with versioning of the submit link. It occurs with wicket 1.2.2. Any ideas anyone? Cheers Erik |
