The system has attempted to use an undefined value

Question

Hi all,

Since a few days I am getting this error:

The system has attempted to use an undefined value, which
usually indicates a programming error, either in your code or some
system code. 
Null Pointers are another name for undefined values.

I have an Application.cfc, which worked just fine a week ago.
Now it causes this error. If I rename the file to Application.cfx,
the pages run without the above error (I get other errors because
there is no Application of course). If I delete the entire contents
of the Application.cfc, I still get this error - which made me
beleive it isn't something in my code. I also do not get an error
line where the error occured or something - just plain this error
message.

I already contacted the hosting provider. They are going to
check whether they did an upgrade or something on the server. In
the meanwhile, anybody out there who had this same problem or who
knows what may cause it? Thanks!!

To test whether the problem is caused by the Application Framework, temporarily switch to Application.cfm, including in it

<cfapplication name="appName_test"
setClientCookies = "yes"
loginStorage = "session"
sessionManagement = "yes"
sessionTimeout = "#CreateTimeSpan(0,0,10,0)#"
applicationTimeout = "#CreateTimeSpan(1,0,0,0)#">

Change the application name, as the old application could still be active in memory. Do you still get the error?
