> how can I ensure that my init function is called
Well, theres a lot of answers to that question, but heres two:
Way I would do it:
<cfscript>
testcom = createobject("component","path.to.component");
testcom.init();
</cfscript>
Another way, which I wouldnt do:
<cfcomponent>
<cfscript>
init();
</cfscript>
<cffunction name="init" access="package" output="no">
<cfset mystruct = structNew()>
<cfset mystruct.initvar = "init varvalue">
</cffunction>
</cfcomponent>

Subject: RE: cfcomponent/function inheritence issue?
Kerry,
Thanks for your help. You're certainly right about the duplicate
function...and of course I should have known that already.
But I'm a little confused about your statement that I shouldn't do this:
<cfif NOT isDefined("mystruct")><cfset this.init()></cfif>
I could call any function in my component at any time, so I have no way of
guaranteeing that init has been called previously. If the above code is not
advised, then how can I ensure that my init function is called?
