Why store the udf as a preference? 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)
