Specifically, it happens when underlying (Java) code sets something to null. CF doesn't grok that and reports that the variable *containing* the null isn't defined (which is, I suppose, actually correct for some values of correct). You can get the same problem with, for example, trying to access missing values in sparse arrays. <cfparam> is your friend, with its default set to something appropriate (I have a Java object I treat as an ersatz null). -- Regards, Pete (jQuery-free) Jordan Horus Web Engineering Ltd http://www.webhorus.net/ phone: +44 1482 446471 mobile: +44 7973 725120 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:344704 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
