Arguments
The arguments for this function are set. You can not use other arguments except the following ones.
| Name | Type | Required | Description |
| list | string | Yes | a string list |
| delimiters | string | No | Characters that separate list elements. The default value is comma. |

For all list functions Railo now supports the optional parameter includeEmptyFields. This parameter indicates whether empty fields (like in the list a,,b) are respected as well. Here’s an example: <cfset a = "1,2,3,,,4,5,6,7"> <cfdump var="#listlen(a,",",true)#"> returns 9 and <cfdump var="#listlen(a,",",false)#"> returns 7 Please note that the default for the includeEmptyFields Parameter is false.
