That'll work. <cfset path=my_url.getpath()/> <cfif isdefined('path')> <!--- ... ---> </cfif> We use a little Java class to tidy this (amongst other things) up that I've attached - with luck the houseoffusion mailing list software will leave it intact. There are a few bits glued into the server scope at the CF end: <cfscript> server.undefined=createobject('java', 'horus.coldfusion.undefined').init(); function defined( value ) { var argc=arguments.size(); value=server.undefined.assigned(value); if (argc eq 1) return value; if (value) return arguments[2]; if (argc gt 2) return arguments[3]; return ''; } server.defined=defined; </cfscript> Using your my_url object, you could then do: <cfdump var=#server.undefined.check(my_url.getpath(), 'NULL!')#/> or <cfset path=server.undefined.check(my_url.getpath())/> <cfif server.defined(path)> <!--- foo ---> <cfelse> <!--- bar ---> </cfif> It's worth noting that the "check" method must be called directly, with the potentially-null-returning Java call as an argument; that's the only way to bypass ColdFusion bleating about an undefined variable. Having a NULL-surrogate value that can be used anywhere in ColdFusion is *hugely* useful; I only wish that Macradobaire had seen fit to do it properly in the first place. -- Regards, Pete Jordan Horus Web Engineering Ltd http://www.webhorus.net/ phone: +44 1275 543971 mobile: +44 7973 725120 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;203748912;27390454;j Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:308065 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4
