This is a browser dependent problem. If you do:
<input name="testtext" type="text" value="">
then most browsers will send an empty variable (except extremely old Netscape AFAIK) if there is no entry made.

This is standard CF behaviour with lists. Adjacent delimiters are treated as one delimiter so you need to put something between them. Try something like:
<cfset listVariable = replace(listVariable, "||", "| |", "all")>
That will force the delimiters apart and then you can strip out the spacer afterwards if you need to.
