Hi all, My wicket app is coming along very nicely, however I have another ajax problem with switching components in an ajax call. here's a simple example:
- I have a page consisting of Panel A. Panel A has a custom component which is a graphical scrollling list. It has custom behavior I wrote which refreshes the list with new images every few seconds. - I have a button to switch out Panel A to Panel B using Ajax. If I click it, then whilst the request is in progress, Panel A's custom component fires its ajax, the request appears to get buffered as my debug window says ' Channel busy - postponing'. Then when the first request returns (having swapped out Panel A for B) the postponed request fires. When it hits the server I get an error message (correctly) stating that the behavior couldn't be found. The error and full stack trace is shown below. I don't mind that the second ajax request is being sent but I really need some way of telling Wicket (or getting wicket to understand) that a previous ajax request changed my page and to just ignore this request if its behavior doesn't exist, rather than throw up a nasty exception. Any ideas on ways I could fix this problem? Thanks, Dean Full error and trace: WicketMessage: component mainPage:current_tab:current_tab:userinfolist not found on page jumbuck.ffweb.wicket.page.FFWeb[id = 0], listener interface = [RequestListenerInterface name=IBehaviorListener, method=public abstract void org.apache.wicket.behavior.IBehaviorListener.onRequest()] Root cause: org.apache.wicket.WicketRuntimeException: component mainPage:current_tab:current_tab:userinfolist not found on page jumbuck.ffweb.wicket.page.FFWeb[id = 0], listener interface = [RequestListenerInterface name=IBehaviorListener, method=public abstract void org.apache.wicket.behavior.IBehaviorListener.onRequest()] at org.apache.wicket.request.AbstractRequestCycleProcessor.resolveListenerInterfaceTarget(AbstractRequestCycleProcessor.java:394) at org.apache.wicket.request.AbstractRequestCycleProcessor.resolveRenderedPage(AbstractRequestCycleProcessor.java:440) at org.apache.wicket.protocol.http.WebRequestCycleProcessor.resolve(WebRequestCycleProcessor.java:136) at org.apache.wicket.RequestCycle.step(RequestCycle.java:1067) at org.apache.wicket.RequestCycle.steps(RequestCycle.java:1153) at org.apache.wicket.RequestCycle.request(RequestCycle.java:501) at org.apache.wicket.protocol.http.WicketFilter.doGet(WicketFilter.java:251) at org.apache.wicket.protocol.http.WicketFilter.doFilter(WicketFilter.java:125) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:202) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) at org.netbeans.modules.web.monitor.server.MonitorFilter.doFilter(MonitorFilter.java:368) 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.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$Http11ConnectionHandler.processConnection(Http11BaseProtocol.java:664) at org.apache.tomcat.util.net.PoolTcpEndpoint.processSocket(PoolTcpEndpoint.java:527) at org.apache.tomcat.util.net.LeaderFollowerWorkerThread.runIt(LeaderFollowerWorkerThread.java:80) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:684) at java.lang.Thread.run(Thread.java:619) -- View this message in context: http://www.nabble.com/More-Ajax-woes-with-behaviors-and-component-replacing..-tf3832524.html#a10850261 Sent from the Wicket - User mailing list archive at Nabble.com. ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
