Trying to remove a userid from a given list. Can't seem to crack it... Errors on the removal at the ListDeleteValue - something I'm missing. On CF8.
<cfset curlist = "#userssigned#"> - say userx:usery:userz
<cfset ud = "#session.user_id#"> - say userz
<cfoutput>
#curlist#
<br>
<br>
#ud#
<br>
<cfset newlist = ListDeleteValue( curlist, "#ud#", ":") />
#newlist# - should delete userz? end up as userx:usery
</cfoutput>

The remove() method is one of the ways you can remove elements from a list in Python. The remove() method removes an item from a list by its value and not by its index number.
You can use the pop() method to remove specific elements of a list. pop() method takes the index value as a parameter and removes the element at the specified index. Therefore, a[2] contains 3 and pop() removes and returns the same as output.
You need to use ListDeleteAt() and also need to find the position of the item in the list using ListFind()
This code works below
Note: You don't need to use "##" when you're setting a variable to another variable
<cfset userssigned = 'userx:usery:userz' />
<cfset session.user_id = 'userz' />
<cfset curlist = userssigned />
<cfset ud = session.user_id />
<cfoutput>
#curlist#<br><br>
#ud#<br>
<cfset newlist = ListDeleteAt( curlist, ListFind(userssigned,ud,":"), ":") />
#newlist# - should delete userz? end up as userx:usery
</cfoutput>
