Listed in the version 11.0.03.292480 Issues Fixed doc 
SSIA, but details: http://cfmlblog.adamcameron.me/2014/04/bugs-in-iterator-functions-in-both.html

Summary:

list = ",2,,4,,,7,,,,";
lengthNoEmpties = listLen(list);
lengthWithEmpties = listLen(list,",",true);

writeDump([list,lengthNoEmpties,lengthWithEmpties]);

writeOutput("<br>listFilter() with empties: ");
filtered = listFilter(list, function(v){
    if (isNumeric(v)){
        return v mod 2; // ie: odd numbers
    }
    return true;
}, ",", true);
writeDump([filtered]);

And results (Railo first):

Array
1	
string	,2,,4,,,7,,,,
2	
number	3
3	
number	11

listFilter() with empties:
Array
1	
string	,,,,7,,,,

So Railo gets it dead right.

ColdFusion:

The following information is meant for the website developer for debugging purposes.
Error Occurred While Processing Request
Parameter validation error for the LISTFILTER function.
The function accepts 2 to 3 parameters.

That's not right. The list iteration functions need to - across the board - also expect both a "delimiters" and a "includeEmptyValues" argument.

This isn't fixed in CF11 Update 3 (as of build 11,0,03,291742). The code in the example returns 7 (instead of ,,,,7,,,,). Example: writeOutput(listFilter("1,,2,,3", function(){return true;}, ",", true));//returns 1,2,3 (bad - should return 1,,2,,3) writeOutput(listFilter("1,,2,,3", function(){return true;}, ",", false));//returns 1,2,3 (good) Thanks!, -Aaron
