key [singleton] doesn't exist

[Chris Blackwell]

I keep seeing this error crop up intermittently, and it requires a re-init of our app to clear the error state.

Its been happening on all Railo 4 versions (currently on Railo 4.2.000).  It looks like either the singleton.instance that is injected into the component metadata is either lost or not created before its used.

I've hacked around this with a try/catch&log @ core/reflect/Class.cfc:42 (which i realize is expensive) to see if the issue goes away in development

But other than that, not sure how else to debug it.

Cheers, Chris

Does it correlate with when your application is started after the application scope timeout ?

Hi Tom,

Yes, i assuming it does, although i haven't added any tracing to confirm this is the case.  This is a management/dashboard app and we mostly see this error on a monday morning, so it seems pretty likely.

Its a FW/1 app so i'm creating CS bean factories in setupApplication() with a parent bf for the app, then one for each subsystem created in setupSubSystem().

I've increased the app timeout and added tracing in Class.cfc in the production environment. So we'll see if it goes away.

I think I remember seeing this occasionally on Railo. It seemed to occasionally clear out cfc metadata every so often or something - it was very odd.

When I had this issue, I made sure the Factory that was being created in onApplicationStart() was inside a lock so it would be single threaded.

i was under the impression that onApplicationStart was single threaded, but maybe thats a flawed assumption.  It wouldn't hurt to chuck locking around the bf creation.  'll give that a try too

cheers, Chris
