Re: ColdFusion ignores empty list elements
Maybe that is :)...I just remeber reading it somewhere..I will openly admit to not using Bluedragon in production...yet. I am toying with CFeverywhere apps right now and I am still soaking up all the BD enhancements so maybe I forgot something...I just remembered reading the enahcnements the other day and thinking jeeze thats nice...no need to us the split UDF here. Its particularly nice when reading comma deliminated rows from a csv.

RE: ColdFusion ignores empty list elements
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: #ListLen( list )# #listGetAt( list, 4 )# 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: 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: This creates instead an array of 4 elements, with the third being empty." Maybe this is what Adam was thinking of?

> Or perhaps BD should have the ability to run in > compatibility mode, without > the added changes. Yea, that'd work. Although personally I think it'd be easier to introduce new functions or possibly in this case an additional argument to the function which tells the function whether empty list elements should be included and defaults to false for compatibility. So listfindnocase(mylist,x) would become listfindnocase(mylist,x,",",true) if you wanted to include the empty elements. At this point BD has been around long enough that it's a choice for them between annoying the living hell out of their existing user base by changing the behavior or continuing to alienate their target market with the variance. s. isaac dealey 954.522.6080 new epoch : isn't it time for a change? add features without fixtures with the onTap open source framework http://macromedia.breezecentral.com/p49777853/ http://www.sys-con.com/author/?id=4806 http://www.fusiontap.com ~| Logware (www.logware.us): a new and convenient web-based time tracking application.

Re: ColdFusion ignores empty list elements
>>syntax variances between them should be limited >>primarily to _new_ functions and tags I agree with you, but the case of empty values in CF is not syntax variance, the syntax is the same. It is actually a bug, for the least a flaw in the design in ColdFusion. Further more, making the function work properly has no or very little impact on existing applications: 1. if a current application has NO empty values in lists, it will still work the same way; 2. If the progammers already broke their nose on the problem, they have implemented some workaround, and this workaround will still work the same way. 3. If a current application may have some empty list elements in the future, the application will still work properly instead of breaking. So where is the problem? Only in the case a programmer exploited this weird behaviour in purpose, and I do not think there must be a lot of such cases. Allaire never admitted it was a bug, because it was THEIR product, MM never did either, because it is THEIR product, for BlueDragon, it is THEIR product also, but not their language, and there is nothing wrong correcting someone else's bugs. -- ___ REUSE CODE!

I don't think it is absurd at all, CFML was started and developed by Allaire
and then Macromedia. The only apparent contribution that NewAtlanta has done
was to copy the end user (meaning developer) functionality and attempt to
subvert market-share from the authors and their intended 'heir'.
All without apparently contributing financially to the actual company that
created CFML, or the one that inherited it directly from the creator.
That's all just my opinion though :)

RE: ColdFusion ignores empty list elements
How hard would it be to quote each of the values? Would '1','2','','4'
still come back as four elements?

Re: ColdFusion ignores empty list elements
> Switch to Bluedragon :)
If BD's interpretation of the list functions isn't the same as CF's
(without creating new functions with different names to handle them
differently) then I'd have to consider that a flaw in BD.
I at one point had a function written to convert lists to arrays and
include empty elements...
myarray = arraynew(1);
f = findoneof(",",mylist);
while (f) {
if (f is 1) { arrayappend(myarray,""); }
else {
arrayappend(myarray,left(mylist,findoneof(",",mylist)));
}
mylist = removechars(mylist,1,f);
f = findoneof(",",mylist);
}
That's from memory -- haven't used it in a long while -- probably not
since cf5 ... and all things considered, the Java version is likely
more efficient.

In pure java you can also do this:
Then you can do
