Yes, that's one way to do it. You can also instantiate an instance of the
newsletter cfc and call the methods directly. So..;
<cfcomponent name="user">
<cfset variables.newsManager = createObject("component", "newsmanager")>
.....
<!--- Check if user has subscribed to any newsletters. If so, insert them
--->
<cfif (arguments.userMailingListID) IS NOT "">
<cfset newsresult =
variables.newsManager.insertNewsSubscription(user_id =arguments.userid,
newcat_id = arguments.usermailinglistid)>
> </cfif>
</cfcomponent>
Whether your want to instantiate or invoke depends on the life cycle of your
user object and whether or not you want to call multiple methods in your
newsletter manager.
