maybe my understanding is a bit off, but the first error (x=y), happens at run time. it's syntax is fine, so the p-code compiles successfully. only when the line is executed is an error generated, as y doesn't exist.
in the second error, there is a syntax error, which is caught before the p-code is compiled. it's not a runtime error, so the exception handling doesn't even come into it.

No; apologies if it wasn't clear. With this in Application.cfm: <cferror type="EXCEPTION" exception="ANY" template="/errors/exception.cfm"> <cferror type="REQUEST" template="/errors/request.cfm"> and just this line in a template <cfset x = y> when y isn't defined, "errors/exception.cfm" is displayed (as you'd hope). However, putting just this line of code <cfset x = CreateDate(Date)> when Date isn't defined, displays a standard-looking ColdFusion error page saying "Parameter validation error for function CREATEDATE", and not "errors/exception.cfm". Anyone know why? And is there a way of using cftry/cfcatch/cfthrow to get it to display "errors/exception.cfm" with an appropriate error message? (I was looking at cfthrow details="" message="" earlier and wondered how they were used) I've only dabbled with exception handling before and really need to get a better grasp of how it works.
