I have tracked this problem down to the server. I am able to run the exact same code on a different server w/o any problems.
Now, I need to find out what is different betweent the two. Maybe it would be prudent to uninstall CF and reinstall it?

In the root of the web site, I created test.cfm and test.cfc as shown here: test.cfm -------- <cfoutput><p>#now()#</p></cfoutput> <cfset result = createObject("component", "test")> test.cfc -------- <cfcomponent displayname="Test" output="no"> <cffunction name="myFun" output="false" returntype="string"> <cfreturn now> </cffunction> </cfcomponent> I received the Null Pointer error when running the test.cfm page. Note, that both of these files are in the same directory. Also, the CFC does not accept any arguments. There is no constructor code, either. I then added a root "/" mapping in CF to point to: "D:\WebSites\Departments\ots.evansville.edu\WebSite" This did not work. I then added a custom tag path to: D:\WebSites\Departments\ots.evansville.edu\WebSite This did not work, either. Should I restart the CF services for some reason? I have not done that since I can "force" an expected error by mis-typing the CFC name in my code. Thanks for any help. -----Original Message----- From: S.

Hi Mike, Not that I'm aware of... I'd be willing to bet that the problem you're having with the null pointer error is a result of this somewhere in your cfc: <cfargument name="x" required="false"> Null pointer errors happen a lot when a default is not specified for a cfargument tag. This to me is the most frustrating thing about the lack of nulls in recent versions of CF -- not that we can't use them in general (although that's frustrating) but that there is an _EXTREMELY_ common circumstance which causes them OFTEN and is neither intuitive nor well documented. If the error occurs while creating the object (before init) I would bet that it calls method in the soft-constructor which doesn't provide a not-required argument with no default value -- and then of course attempts to use that undefined argument which results in the null pointer error. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Message: http://www.houseoffusion.com/lists.cfm/link=i:4:234698 Archives: http://www.houseoffusion.com/cf_lists/threads.cfm/4 Subscription: http://www.houseoffusion.com/lists.cfm/link=s:4 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4 Donations & Support: http://www.houseoffusion.com/tiny.cfm/54
