cffunction possible error in output?

Consider this function which returns whatever its input is::

<cffunction name="FredTest" output="yes" access="public" returnType="string">
<cfargument name="lsVarIn" type="string" required="true"/>
<cfreturn lsVarIn />
</cffunction>

I test the function using: ABC#FredTest("DEF")#GHI

I expected to see the output as ABCDEFGHI but instead got ABC DEFGHI.  I can't figure out why.  Everytime I try to use cffunction to return a string CF adds a space in front of the output.  Any idea why?  Thanks.

    It is not an error. The extra space is just the empty space from the body of the function. 

     

    Solution:

    Set output to "no" in the function definition. That is, output="no".

    That is the recommended setting, unless in cases where you have good reason to set it to "yes".
