cfloop list doesn't return null values
I have a list like ",89,90,,87". When I use cfloop go to through it, I only get 3 values instead of 5 with 2 nulls. How do I specify the <cfloop> tag to return 5?
I want to have something like this:
Instead, I get this:
Thanks in advance for any help!

The unfortunate answer is there is no way to get CFLOOP to do this on its own. CF treats multiple null delimiters as one delimiter, which is a benefit in some situations and a pain in the butt in others. You could either send the string in with spaces between the delimiters, or run a replace function that adds a space after each delimiter, but then you must remember to trim() the value when you use it, like this:
<cfset list = "1,2,3,,5,,,,9,10">
<cfset counter = 0>
<cfloop index="thisElement" list="#replace( list, ',', ', ', 'All' )#" delimiters=",">
<cfset counter = counter + 1>
Element #counter#: #trim( thisElement )#<br>
A custom tag or function could also handle this pretty easily.
