While I think the suggestion of switching to BlueDragon is an excellent one
to consider, the following code works exactly the same on BD 6.2 and CFMX
6.1:
<cfset list ="a,b,c,,,d">
<cfoutput>
#ListLen( list )#<br>
#listGetAt( list, 4 )#
</cfoutput>
As far as I know, all of the list functions work the same on BD as on CFMX.
We did, however add an optional enhancement to the ListToArray() function;
from the BlueDragon 6.2 CFML Enhancements Guide:
"BlueDragon adds a new third argument to ListToArray(), a boolean
value, which determines whether to include empty list elements in the
resulting array. The default is no, which causes it to operate consistently
with ColdFusion. Consider the following:
<cfset list = "1,2,,3">
<cfdump var="#listToArray(list,",")#">
Both ColdFusion and BlueDragon will return an array of 3 elements,
even though there are 4 items in the list, the third of which is empty. Use
the newly available third argument to change this behavior:
<cfset list = "1,2,,3">
<cfdump var="#listToArray(list,",","yes")#">
This creates instead an array of 4 elements, with the third being
empty."
Maybe this is what Adam was thinking of?
