    To reproduce: Login into uportal quickstart 2.4.2. and then click on 'Portlet Examples' then 'Misc Test' then the '>>' button click CWebProxyExamples on the Tomcat Numguess game select a number 1-100 click submit, right click with the mouse click back twice. You will be back on the page you saw after clicking the >> button. Now click << I see 'Cannot start uPortal' in Firefox. In portal.log I see ERROR [http-8080-Processor22] portal.ExceptionHelper.[] Mar/27 12:56:31 - Programming error java.lang.RuntimeException: java.lang.NullPointerException at org.apache.xalan.transformer.TransformerImpl.run(TransformerImpl.java:3418) at org.apache.xalan.transformer.TransformerHandlerImpl.endDocument(TransformerHandlerImpl.java:389) at org.jasig.portal.utils.SAX2FilterImpl.endDocument(SAX2FilterImpl.java:684) at org.jasig.portal.utils.SAX2FilterImpl.endDocument(SAX2FilterImpl.java:684) at org.jasig.portal.layout.AggregatedLayout.writeTo(AggregatedLayout.java:448) at org.jasig.portal.layout.AggregatedLayoutManager.getUserLayout(AggregatedLayoutManager.java:915) at org.jasig.portal.layout.TransientUserLayoutManagerWrapper.getUserLayout(TransientUserLayoutManagerWrapper.java:134) at org.jasig.portal.UserInstance.renderState(UserInstance.java:527) at org.jasig.portal.UserInstance.writeContent(UserInstance.java:205) at org.jasig.portal.PortalSessionManager.doGet(PortalSessionManager.java:269) Thanks for looking at this, it is an unlikely sequence but still a bug- the session is unuseable and I have to manually call the Logout servlet via the address bar to continue.
