I think the issue is more so the fact that if the value is null, then structKeyExists returns false, for example:
<cfscript>
s = {};
s.whatever = javaCast("null", 0);
writeDump(s);
writeOutput( structKeyExists(s, "whatever") );
</cfscript>
In your example you are not passing the whatever argument to the function, so it has a null value as well.
I think it would be worth documenting that when a structure value is null, structKeyExists will return false - anyone else have opinions?
The description should be updated to reflect the fact that if used on a scope, such as arguments, the function returns false even though the key is present (as seen using writeDump), with value
undefined
