Question |
| When using comma delimited ColdFusion lists, why are empty elements ignored? | ||
| ColdFusion lists are not CSV comma-delimited lists and do not behave as CSV lists do. ColdFusion ignores empty list elements, so ListLen("a,b,,d,e") will return 4 (not 5), and ListGetAt("a,b,,d,e", 5) will throw an error. To convert a ColdFusion list to a CSV list, use Replace() and replace all ",," (comma comma) with ", ," (comma space comma) - a space is a valid list member value and ColdFusion will not ignore it. |

| Well the replace method would do the job but if you test for empty elements and put a number or an empty string, this also would work in eliminating those errors thrown. |
