On an incidental note, I don't think there is any need to make the call <cfset onSessionStart()>. In fact, it is rarely necessary to manually call any of the functions in Application.cfc. When you do so, strange errors sometimes result. That is so because they are not merely functions, but event-handlers. For example, it cannot be a good thing to manually call the function while it continues to lock a thread that started when the event last fired. ... View more

Yes, I have tried it all. Nothing works! I've even disabled cookies and tried to produce the error on my own by manually firing onSessionEnd and I get no error. I'm getting about 40 errors a minute all the same. There has got to be a reason! Time to roll back the sleeves. Put the code <!--- get a clone of the entire session structure---> <cfset application.sessions=structnew()> <cfset application.sessions=duplicate(session)> at the beginning of onSessionStart, and put <!--- dump session structure to the logs as sessionDump.log---> <cfsavecontent variable="sessionDump"> <cfloop collection="#application.sessions#" item="sessionKey"> <cfoutput>#application.sessions[sessionKey]#; </cfoutput> </cfloop> </cfsavecontent> <cflog file="sessionDump" text="Dump of session structure:#sessionDump#"> at the bottom of onError. It is to answer the question whether or not there is a session. Perhaps the structure is deleted right after you create it. However, since sessions have something to do with the exception, you cannot use that scope within onError, hence my use of the application scope. Now, what does the log file show? ... View more

Yes, strange, indeed. Are application and session variables enabled in the Coldfusion Administrator? Do you have something like this just after the cfcomponent tag in Application.cfc <cfset This.applicationTimeout="#CreateTimeSpan(1,0,0,0)#"> <cfset This.sessionmanagement="True"> <cfset This.sessiontimeout="#CreateTimeSpan(0,0,20,0)#"> The "rootCause" workaround is itself not perfect. For example, it instructs a void method, onError(), to return. What happens when you remove it altogether from onError? And when you put some dummy code in onSessionEnd, like this? <cffunction name="onSessionEnd"> <cfargument name = "SessionScope" required=true /> <cfargument name="ApplicationScope" required=true /> <cfset test_var1 = Arguments.SessionScope.URLToken> <cfset test_var2 = Arguments.ApplicationScope.name> <cflog file="#This.Name#" text="session's URLToken= #test_var1#.
