The problem that I have had with IsDefined on nested structures such as arguments.x.y
is that IsDefined("arguments.x.y") will throw an error if x or y is the empty string
(or not strings) because that is not a valid struct key name.
You may have to do something like (x NEQ "" and y NEQ "" and
IsDefined("arguments.x.y").
If x and y are nonempty strings, then I believe IsDefined("arguments.x.y") should work
as expected.
Not sure if that is the problem you are seeing, though.

I think the error is on the IsDefined("arguments.x.y")
You may have to use something like structKeyExists(arguments.x, "y")
instead.

Subject: [CFCDev] Short circuiting??
If I have this line (I don't really use x and y):
<cfif IsDefined("arguments.x.y") AND ListLen(arguments.x.y)>
then I get this error message in my CFC (CFMX6.1) pointing to the line
above:
"Element x.y is undefined in ARGUMENTS."
I thought CF used short-circuiting - it does elsewhere, why not here?
Can anyone confirm that I have to change the line to:
<cfif IsDefined("arguments.x.y")>
<cfif ListLen(arguments.x.y)>
Thanks,
Douglas
