[coldspring-dev] Application Scope out of sync?

Jeff, are you also using model-glue to access the same bean factory?

What I ended up doing, which is strictly in the workaround category, is check for the existence of my serviceFactory in onRequestStart, and re-loading it if not.  That "works" but I wish I knew what was really going on.

Thanks Chris. The swf is embedded in a .cfm page, though.  I would think that onApplicationstart() would be run when I'm hitting my remote facade which lives beneath the Application.cfc (of course).
 
I'll try destroying the services.  I could also check for the existence of the services in the application scope on each request, but I've heard that there are some security issues with flash remoting and the onRequestStart() function.

What is probably happening here is your swf is embedded in an html file. When it accesses the remote facade, the application has timed out. You could change your index.html file to be index.cfm, which would restart the application, or but a ping service in your main.mxml file that just hits a cfm page on creationComplete, which will have the same effect. I would also suggest you have your services destroyed onApplicationEnd in application.cfc

I've run into a phenomena I have no explanation for, and I'm looking for advice.  Here's the scenario:

I've added a function loadFramework() to my Application.cfc that is run during onApplicationStart().

Then I've got a remote façade that is being used to provide services to a Flex 2 app, using CFMX 7.02 as the backend.

Periodically, I'm getting an error : Element SERVICEFACTORY is undefined in a Java object of type class [Ljava.lang.String; referenced as ". Note: SERVICEFACTORY is residing in the application scope.

This error disappears if I reload ColdSpring.  I could work around it by checking for it's existence in my Remote façade and loading it, but that is a kludge. What I don't understand is how my SERVICEFACTORY could not exist in the application scope if onApplicationStart() is reloading my framework.

Note my call to loadFramework() isn't CFLOCKed although the code in the function is - perhaps it should be? To prevent a race condition?

Anyone encountered this or something similar?
