I reckon a multidimensional array must be seen as complex.?!

They are complex. I guess its the way ColdFusion handles them. I don't know
how it stands in CFMX but in the c++ coldfusions of yore its clearly a
throwback to the way c++ handles memory. That is why I would guess that
OBJECTS and queries are also moved, copied , passed by reference ( pointer )
than by value ( a true copy ). Don't ask me what happens to that array that
is three levels done in a structure of structures!!
Perhaps Lucas or another MacroMeanie can clear this up if they are on list.

really, so Arrays will be fine also?........hmmmm....... I thought
they were
complex variables?

I amnot certain about Queries or com/java objects but I know you are
safe
with Arrays and Wddx. Coldfusion copies arrays by value, wddx is
just a
string (therefore a simple value) . Structs are copied and passed by
reference . Queries anyone ? Com / Java Objects ? (I'd love to know,
must
languages include such things in the docs mind you!)

Thanks Guys,
So it is clear : using <cfset to copy session to request is
AOK as
long as
the value is a simple variable but NOT OK if its a complex
variable
(array,
structure, wddx....)?

no, but if it was indeed a pointer, surely it would bomb?

not surprising really, as the checking is on session
variables not
request
variables.
