Your suggestion is good as soon as the set of function is pre-defined and well known, which is not the case. The object I am talking about is part of a completely dynamic development framework and must be able to handle other set of functions without changing the code.

I'd just store a string, ie, pageA.display="thumbnail" or pageA.display="Summary", then you could do: <cfif pageA.display is "thumbnail"> <cfoutput>#displayThunbnail(.... etc Or even easier. Write a UDF called displayContent. It takes as an arg what style to display and the data to show. So you could do: displayContent("thunbmail",artistnail) ======================================================================= Raymond Camden, ColdFusion Jedi Master for Mindseye, Inc Email : [EMAIL PROTECTED] WWW : www.camdenfamily.com/morpheus Yahoo IM : morpheus "My ally is the Force, and a powerful ally it is." - Yoda > -----Original Message----- > From: DDE [mailto:[EMAIL PROTECTED]] > Sent: Wednesday, February 05, 2003 1:17 AM > To: CF-Talk > Subject: RE: WDDX and UDF > > > It is much more complex than that and it doesn't concern > pages but display objects ...
