This is the first I've seen/heard a "super" qualifier. What does it point
to/stand for?

Subject: RE: extends + init() = returntype confusion
First, IMHO, having init() return a reference to 'this' is bad style. It
only makes things more confusing.
But to answer your question, you should have init() return the type of the
current CFC. When you call super.init(), you shouldn't be returning. ALL
your init methods should follow this format:
<cffunction name="init" ... Returntype="typeOfThisCFC">
<cfargument ... />
...
<cfset var ... />
...
<cfset super.init() />
<!--- any initialization for this object --->
<cfreturn this />
</cffunction>
Super.init() should ALWAYS be the first thing in the method, except for
'var' declarations, if you need any.
