Re: Ordered Argument names
but if the arguments are named, why does the order matter? Ordinarily, over 99% of the time, it wouldn't. But I have a function which is called like this: doStuff( a:data , x:data ) doStuff( b:data , x:data ) doStuff( c:data , x:data ) doStuff( x:data ) So being able to determine the first arg name would be useful. The workaround I currently have gets the arg list then replaces out X, unless it's the only argument. And that only works because there's never more than two args in any one call... if there were more I'd probably have to resort to providing a separate list of arguments, and I don't like repeating myself. ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;207172674;29440083;f Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:313182 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4
RE: Ordered Argument names
So being able to determine the first arg name would be useful. Structures are unordered. If you want an ordered container, consider using an array. Alternatively, you could, of course, simply sort the keys alphabetically after retrieving them, if all you need is consistency.

RE: Ordered Argument names
Does anyone know how to make CF provide a list of the names of Arguments in the order provided and without using cfargument tag? StructKeyList/StructKeyArray returns an arbitrary order in CF8, and a random order every time in CF7. Using Array functions on the Arguments scope results in a random order every time in CF7 and CF8.

Re: Ordered Argument names
using your code on CF8 (8,0,0,176276), i get the structs returned in the same order (alpha by key name) each time. neither arbitrary nor random. i understand this isn't necessarily what you want... but it does seem to be consistent (for whatever that's worth).

Re: Ordered Argument names
You should be able to loop through the arguments array: cfset a = arrayNew(1) / cfloop index=i from=1 to=#arrayLen(arguments)# cfset arrayAppend(a, arguments[1]) / /cfloop cfdump var=#a# / Nope, that gives values not names (assuming 1 - i) Also, it doesn't come out in the same order each time. It *should* since arrays are supposed to be ordered, but in my version of CF the values are switching around each refresh. ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;207172674;29440083;f Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:313149 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4

@Dan - Good question. If you are sending the argument name in the call to the cffunction then they can be in any order and the cffunction will figure it out. -Chuck ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;207172674;29440083;f Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:313153 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4

itself. Talk about Friday density ;-)

Yes, it is not. I believe it is an internal class that implements from
java.util.Map. Now if it was an ordered collection, that would be sweet.
