this should have occurred to me before, but I found a good workaround for the fact that the arguments array in MX is not an array. I realized that isarray(arguments) returns false in MX or true in CF 5, so a reasonably simple function allows me to produce consistent results on both CF 5 and MX with other functions which seek to alter the arguments array using array functions that don't work on the arguments array directly in MX.
function argstoarray(args) { var x = 0; var args2 = false; if (not isarray(args)) { args2 = arraynew(1); for (x = 1; x lte arraylen(args); x = x + 1) { arrayappend(args2,args[x]); } args = args2; } return args; } So if I have a function which needs to alter the arguments array with array functions, I would rewrite something like this: function myfunction(x,y,z) { arguments[1] = blahblah(x,y,z); arraydeleteat(arguments,3); arraydeleteat(arguments,2); request.tapi.js.call("funcname",arguments); } which works on CF 5 only to this for CF 5 and MX: function myfunction(x,y,z) { var args = request.tapi.argstoarray(arguments); args[1] = blahblah(x,y,z); arraydeleteat(args,3); arraydeleteat(args,2); request.tapi.js.call("funcname",args); } Since it only duplicates the arguments array if it's not an array, the only added overhead for the function on CF 5 is calling the argstoarray() function which simply returns the unmodified arguments array and this preserves the efficiency of the original code for CF 5. MX will still suffer added overhead from having to copy the vars into an array but there's not a whole lot I can do about that unfortunately. Figured somebody might find this usefull. :) s. isaac dealey 954-776-0046 new epoch http://www.turnkey.to lead architect, tapestry cms http://products.turnkey.to tapestry api is opensource http://www.turnkey.to/tapi certified advanced coldfusion 5 developer http://www.macromedia.com/v1/handlers/index.cfm?ID=21816 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Archives: http://www.houseoffusion.com/cf_lists/index.cfm?forumid=4 Subscription: http://www.houseoffusion.com/cf_lists/index.cfm?method=subscribe&forumid=4 FAQ: http://www.thenetprofits.co.uk/coldfusion/faq Signup for the Fusion Authority news alert and keep up with the latest news in ColdFusion and related topics. http://www.fusionauthority.com/signup.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4
