Re: [cfaussie] Count the number of arguments passed into a function.
Unfortunately it's too late to strive for consistency at this point.
The odd behaviour of structKeyExists is due to the underlying Java
implementation, the inconsistent handling of null values in Adobe CFML, and
backwards compatibility concerns.
CF structs are special Java objects that implement the java.util.Map
interface. The method to retrieve a value in a Map is get(key).
Map.get(key) returns a Java null if the key does not exist in the map.
However if the key exists but the value is a Java null, then Map.get(key)
also returns null, so Map.get(key) alone is insufficient to tell whether
the key exists or not. Given the behaviour of CF's structKeyExists(), it is
extremely likely that Adobe implemented it via Java's Map.get(key).
The issue could be worked around by exposing Java's Map.containsKey(key),
but that would expose the other two problems. CF is still a bit confused
about null values. In many cases CF treats a variable with a null value as
if it doesn't exist (much like a struct key with a null value). At other
times it automatically converts it to an empty string. Changing
structKeyExists() to return true for keys with null values would also
require a sensible way for CF to handle those null values. A number of
proposals have been made about this. My preference is the implementation of
a proper void type (whose only possible value is null) in CFML.
That brings us to the third problem. There is lots and lots of legacy code
that relies in the existing behaviour that has been around since ColdFusion
MX. I've written cfif structKeyExists(arguments,foo) more times than I
can count. If structKeyExists() were changed to return true for keys with
null values, a lot of that code would break. Adobe's policy for the
evolution of CF has been to avoid the creation of such severe
backwards-incompatibilities, and I don't see Adobe changing it's position
on this any time soon.
Someone who feels passionately about it should file a bug report (if they
haven't already), but I'm almost certain that Adobe will treat it as a
wontfix.

Hey Bau Co, this one's been bending my brain for a few hours now. It's
an interesting thread I read it lots. Please excuse me for just rambling a
bit, so I can sleep tonight.
@Dale
I agree StructKeyExists will return false when the key exists, but the
value is null, ie;
cfset theStruct={'theKey'=javacast('null',0)}
cfdump var= #theStruct#
cfdump var=#structKeyExists(theStruct,'theKey')#!--- outputs NO ---*
***
I *think* I agree it's a bug. But with CF that key with a null value is
not very useful. It's one of those things that's existed for a long time
and for good or bad, it's one reason I use IsDefined() more. Will it ever
get 'fixed'? Does it really need to be? Should they or should they not
change it?
It gets a bit philosophical, eh. I don't see this exact bug in the
tracker, so I wonder if this is one of those issues that's been done to
death. Maybe there's a definitive answer out, perhaps it's unimportant? If
not it really should be logged as a bug.
@Gavin
Your issue is of course related. The cfargument tag defines the keys in
the arguments collection, but your default values are undefined. When the
method is invoked the arguments collection is updated NOT overwritten. This
is also the case when using argumentCollection, ie;
cfset someMethod(argumentCollection={something='something'})
A bit annoying? Maybe. Perhaps it has a purpose. I tend to think of it as
a bug. But again it's easy
Re: [cfaussie] Converting boolean YES to true
The issue here is not one of static vs. dynamic languages. JavaScript is
dynamic but doesn't have this difficulty with booleans that Adobe CF has.
The problem is due to two characteristics of Adobe CFML:
1. Boolean is not a true primitive type.
2. Boolean operators return the string YES for true and NO for false.
Most people who encounter problems with booleans in conversions between CF
and other representations blame (2) because it is immediately noticeable,
but the true root cause of the problem is (1). The lack of a primitive
boolean type means that there will always be some values that will be
handled incorrectly in conversions between CFML and representations with
real booleans like JSON.
Adobe doesn't make it obvious that boolean is not a primitive type in CFML.
CFML has standard boolean operators and constants, but if you play with them
enough you will find that there is no true true value in CF.
Code:
cfscript
foo = true;
bar = True;
baz = TRUE;
/cfscript
cfoutput
foo = #foo#br
bar = #bar#br
baz = #baz#br
/cfoutput
Output under Adobe CF 9.0.1:
foo = true
bar = True
baz = TRUE
Languages with boolean primitives treat 'true' as a single literal value. In
the above example the values of the 3 ColdFusion variables were converted to
3 different strings, so they could not have been set to the same literal
value even though they are all supposed to be true. It looks like CF
implicitly converts the barewords true and false to strings and
preserves their original case.
Adding a new primitive type (even one as simple as boolean) to a programming
language is no small thing. If it ever arrives in Adobe CF it would almost
certainly be part of a major release. Then and *ONLY* then should Adobe add
a toBoolean() function.
In the meantime, I've written myself a simple UDF to handle issue (2):
string function trueFalseFormat(boolean booleanValue required, string
trueString=true, string falseString=false) {
return arguments.booleanValue ? arguments.trueString :
arguments.falseString;
}
With this I can use #trueFalseFormat(val)# to get a JSON boolean or
#trueFalseFormat(val,1,0)# to get a SQL boolean (which is rare but sometimes
necessary).
Note that none of this should be a problem when writing ColdFusion code that
does not interface to other systems. If your code accepts a boolean value as
an argument or return value, you should not write your code to expect the
value to be exactly TRUE or FALSE or YES or NO. If you need the
value for conditional logic, use it as is. If you need to output the value,
then you should convert it to the desired format first.

Duplicate works on CFC instances, so Duplicate(this) would work. Of course
