[CFCDev] Check for Empty Strings in Required String Arguments

[Dawson, Michael]

How many of you check for empty strings in required string-type
arguments?

For example, I have this function:

<cffunction name="mySplit" return="array" ...>
    <cfargument name="myList" type="string" required="yes">

    <cfreturn listToArray(arguments.myList, ",")>
</cffunction>

Then, I call the function like this:

<cfset result = mySplit("")>

Do you let this function return an empty array or do you throw an error?
What is the general consensus?  Should empty strings _always_ be allowed
since they tend to be an exception to required arguments?

Thanks
