    text
    copied!<p>Since we upgraded our development servers from Domino 8.5.3 to 8.5.3 FP1 we encounter a very strange problem. We use the xe:viewJsonLegacyService to ouput the view contents in json format and dojo xhrGet with param sync:false. This way we are able to fire multiple requests at once to the xe:viewJsonLegacyService xagent page and process them when the request is done.</p> <p>After Lotus Domino FP1 the sync:false is not usable anymore, if we fire three simultaneous requests it will return error 500 for two requests and success on one request (every time). I created an example database which shows you what goes wrong. But I'm not sure this is because of a problem in the Extension Library or Xpages.</p> <p>Maybe someone have experience with this and maybe a workaround?</p> <p>I created a sample application for download <a href="http://www.openntf.org/Projects/pmt.nsf/C3765C6C79C09D5A86257A68003D3149/%24file/xhrprobl.zip" rel="nofollow">here</a> where I demostrate the issue. It will fail on a Domino 8.5.3 SP1/SP2 installation but not on a Domino 8.5.3 installation. It requires the Extension Library.</p> <p>Edit: this is the stacktrace that returns from the server java.lang.NullPointerException com.ibm.xsp.webapp.FacesServlet.acquireSyncToken(FacesServlet.java:285) com.ibm.xsp.webapp.FacesServletEx.serviceView(FacesServletEx.java:161) com.ibm.xsp.webapp.FacesServlet.service(FacesServlet.java:160) com.ibm.xsp.webapp.FacesServletEx.service(FacesServletEx.java:138) com.ibm.xsp.webapp.DesignerFacesServlet.service(DesignerFacesServlet.java:103) com.ibm.designer.runtime.domino.adapter.ComponentModule.invokeServlet(ComponentModule.java:576) com.ibm.domino.xsp.module.nsf.NSFComponentModule.invokeServlet(NSFComponentModule.java:1281) com.ibm.designer.runtime.domino.adapter.ComponentModule$AdapterInvoker.invokeServlet(ComponentModule.java:847) com.ibm.designer.runtime.domino.adapter.ComponentModule$ServletInvoker.doService(ComponentModule.java:796) com.ibm.designer.runtime.domino.adapter.ComponentModule.doService(ComponentModule.java:565) com.ibm.domino.xsp.module.nsf.NSFComponentModule.doService(NSFComponentModule.java:1265) com.ibm.domino.xsp.module.nsf.NSFService.doServiceInternal(NSFService.java:653) com.ibm.domino.xsp.module.nsf.NSFService.doService(NSFService.java:476) com.ibm.designer.runtime.domino.adapter.LCDEnvironment.doService(LCDEnvironment.java:341) com.ibm.designer.runtime.domino.adapter.LCDEnvironment.service(LCDEnvironment.java:297) com.ibm.domino.xsp.bridge.http.engine.XspCmdManager.service(XspCmdManager.java:272) </p> <p>I have opened up a PMR at IBM. This will also happen when you upgrade from Domino 8.5.3 UP1 to FP1+.</p>
