Ok, I wrapped the the invokeSessionEvent call in a try catch, and got
the following error:
Variable invokeSessionEvent is undefined?!!! That is very weird
indeed. Does anybody have any idea why this would be happening? Even
though the invokeSession Event is defined right below the OnSessionEnd
funcion?
<cffunction name="onSessionEnd" output="false">
<cfargument name="sessionScope" type="struct" required="true" />
<cfargument name="appScope" type="struct" required="false" />
<cftry>
<cfset invokeSessionEvent("modelglue.onSessionEnd",
arguments.sessionScope, arguments.appScope) />
<cfcatch type="any">
<cflog file="#arguments.appScope.applicationname#"
text="onSessionEnd Error: #cfcatch.type# - #cfcatch.message# -
#cfcatch.detail# - #cfcatch.stackTrace#" />
</cfcatch>
</cftry>
</cffunction>
<cffunction name="invokeSessionEvent" output="false" access="private">
<cfargument name="eventName" />
<cfargument name="sessionScope" />
<cfargument name="appScope" />
<cfset var mgInstances = createObject("component",
"ModelGlue.Util.ModelGlueFrameworkLocator").findInScope
(arguments.appScope) />
<cfset var values = structNew() />
<cfset var i = "" />
<cfset values.sessionScope = arguments.sessionScope />
<cfset values.appScope = arguments.appScope />
<cfloop from="1" to="#arrayLen(mgInstances)#" index="i">
<cfset mgInstances[i].executeEvent(arguments.eventName, values)
/>
</cfloop>
</cffunction>
