I would agree with Peter. In this case you might want to use the
preProcess method within a plugin as an example:
<cffunction name="preProcess" access="public" returntype="void"
output="false">
<cfargument name="eventContext"
type="MachII.framework.EventContext" required="true" />
<cfset var event = arguments.eventContext.getNextEvent() />
<!--- create an error/msg object once for e/ event cycle --->
<cfif NOT event.isArgDefined('myPersistentVariable')>
<cfset event.setArg('myPersistentVariable', 'Some value for this
variable') />
</cfif>
<cfreturn />
</cffunction>
