Sure there is.
According to Coldfusion, position 6 contains the value of "7" because it
doesn't recognize empty positions.
Personally, I *HATE* that.
<cfset foo = "1,2,3,4,5,,7,8".
<cfset foo = replace(foo,",","xxx,xxx","ALL")>
<cfset bar = listGetAt(foo,6)>
<cfset bar = REReplace(bar,"^xxx(.*?)xxx$","\1","ALL")>
<cfif bar eq "">
The item at position 6 is empty.
<cfelse>
The item at position 6 is not empty.
</cfif>
The regex may be wrong but you get the idea.
