Young Jedi,
Be careful with the Java split method... In your example, the length is
indeed 4... However, this:
<cfset lst = "jedi,homer,,," />
#ArrayLen(lst.split(","))#
Only has TWO array elements. It seems to only count list items until no more
valid items are found. This seems to be confirmed at the bottom of:
http://www.rgagnon.com/javadetails/java-0438.html
An interesting thing about String.split():
" s".split(" ") -> {"","","s"}
"".split("" ) -> {""}
" ".split(" ") -> {} (!)
" ".split(" ") -> {} (!)
" s ".split(" ") -> {"","","s"} (!)

You could possibly do something like...
<cfset lst = "jedi,homer,,rocks" />
<cfoutput>#ArrayLen(lst.split(","))#</cfoutput>
Which will output 4 and not 3
