Symptoms
You will notice that the page flow application on WLW runs fine for some time and then you will see the below error:
java.lang.NullPointerException
at org.apache.beehive.netui.pageflow.internal.AdapterManager.getServletContainerAdapter(AdapterManager.java:43)
at org.apache.beehive.netui.pageflow.internal.AdapterManager.getServletContainerAdapter(AdapterManager.java:43)
This is because the servlet context is null. At this time no other page flow in the application is accessible.
