Coldfusion - init() with arguments, and "this" scope

Ok, I'm not sure why this is, but if I invoke an init() function for my Logger.cfc, my local methods need to be explicitly called with "this":

<cfset cfcLog = createObject("component",".Logger").init("workflow")>
<cfset cfcLog.logger( "this is an error" )>

Here is the error:

Entity has incorrect type for being called as a function.

The symbol you provided file is not the name of a function.

Here is the original function:

<cfcomponent name="Logger" ...    
    <cffunction name="logger" 
                returnType="void"
                access="public"
                output="no"
                hint="log an entry to a log file, send email, or both 
                      @param  message  string    required    text of log entry
                      @param  logType  string                information/warning/error/fatal (default information)
                      @param  action   string                file/mail/all (log to file, send mail, or both log and send email) (default file)
                      ">
        <cfargument name="message" type="string" required="yes">
        <cfargument name="logType" type="string" default="Information">
        <cfargument name="action" type="string" default="file">

        <cfswitch expression = "#action#">
            <cfcase value="file">
                <cfset file( message, logType )>
            </cfcase>
            
            ...

And, here is the fix:

<cfcomponent name="Logger" ...    
    <cffunction name="logger" 
                returnType="void"
                access="public"
                output="no"
                hint="log an entry to a log file, send email, or both 
                      @param  message  string    required    text of log entry
                      @param  logType  string                information/warning/error/fatal (default information)
                      @param  action   string                file/mail/all (log to file, send mail, or both log and send email) (default file)
                      ">
        <cfargument name="message" type="string" required="yes">
        <cfargument name="logType" type="string" default="Information">
        <cfargument name="action" type="string" default="file">

        <cfswitch expression = "#action#">
            <cfcase value="file">
                <cfset this.file( message, logType )>
            </cfcase>
            
            ...
