Interesting that your observations yielded that conclusion. I had a similar problem where a bit of code was deleting the CFTOKEN cookie. In CF 4.5, no big deal, a new CFID/CFTOKEN is generated because it can't find the CFID:CFTOKEN pair in the database (i.e., 123:[blank]). In MX, I get a Null Pointer error and my cfapplication tag is shown in the debug output as being the line where the error is occurring. It turns out that the underlying mechanism that does the select against the CDATA and CGLOBAL tables chokes because the CFTOKEN value is now null. Once I tracked it down, I sort of understood the reasoning, but the error message is awfully misleading and essentially useless, and, like you, it's another undocumented changed between pre-MX and MX. I feel your pain Bud.
