Since this topic is on the table, why am I getting this error (other
than my lack of understanding)
Local variable sFacade on line 28 must be grouped at the top of the
function body.
-- Here is the function. if I take off the var it does not error.
<cffunction name="OnRequestStart" access="Public"
returntype="void" output="false" hint="I am an event handler.">
<cfargument name="event" type="ModelGlue.Core.Event"
required="true">
<cfset LoadAppSettings(CreateTimeSpan(3,0,0,0))>
<cfif len(arguments.event.getValue('logout'))>
<cfset var sFacade = createObject("Component",
CERESII.model.Facade").init('session') />
<cfset sFacade.add('loggedin',false)>
</cfif>
</cffunction>

It's very important if you are doing any type of recursion.
