Something like this should work (not tested)
<cfset myList = "2,2,1,3,4,1,2,1">
<cfset tmpStruct = StructNew()>
<cfloop list="#myList#" delimiters="," index="current">
<cfset tmpStruct[current] = true> <!--- add the number to the hash table --->
</cfloop>
<cfset myList = ""> <!--- re-set the list and rebuild it! --->
<cfloop collection="#tmpStruct#" item="current">
<cfset myList = ListAppend(myList, current)>
</cfloop>

Subject: Hashtable in CF?
Well, I don't know if a hashtable is exactly what I need since I'm not 100
percent familiar with that kind of datastructure.
But what I do need is a function that feeds in a long list of delminated
data and parses out one copy of each unique value (where each value might be
repeated several times).
If I have a list of (2,2,1,3,4,1,2,1)
How do I get (2,1,3,4) // order isn't important // ?
You ever do anything like this? Sample code to share? A suggested algorithm?
(Actually, as I write this, an idea springs to mind, but I'll post anyway in
case there's a better idea out there or something I can learn from).
