Subject: Singleton Error
I am using the current ColdSpring Alpha and occasionally I experience
an error.  I am a bit of a newbie, so its probably due to something I
have done with my code, but I wanted to run this past the group to see
if there are any ideas:

Message  key [SINGLETON] doesn't exist in struct
(keys:functions,synchronized,persistent,extends,name,path,hint,properties,a ccessors,type,output,fullname)

Stacktrace      The Error Occurred in
 C:\RailoExpress\webroot\coldspring\core\reflect\Class.cfc: line 42
40: //have to do this stupid juggling because CF8 'can't find
'setLength() on a Builder'
41: var builder = 0;
42: var reflectionService =
getComponentMetaData("coldspring.core.reflect.ReflectionService").singleton .instance;
43:
44: //builder.setLength(builder.lastIndexOf(".")); << CF8 fails on
this because it can't resolve Java Methods. Grrr.

Thank you

I think there was a a patch in the latest Railo that has a regression in
regards to storing things in metadata, as I'm seeing this issue locally as
well, but not on ACF.

I will have to investigate and see what the bug is.

I see this too on Railo 4.0.1. I thought it was my application code,  but
apparently not.

I find if you keep refreshing, it ends up going away, but obviously, that's
not practical.

Mark,

Thanks again for your help on this.  Do you think the problem might be
related to using it as a factory for ORM objects?
Should I go back to using the older released version of Coldspring?  Any
other advice and ideas welcome!

So I just tried this on  3.3.4.003 , the stable release, and all worked
perfectly.

So looks like it's a weird bug in Railo. Talking to the Railo team about
it, not sure what is going on there.
https://groups.google.com/forum/?fromgroups=#!topic/railo/MC4cQwZ7vfE

But quick answer - roll back to stable.

Mark,

Thanks again for trying to sort this out.  I want to note that for me,
reloading does not avert the problem--even reloading multiple times.

That's weird - works fine for me.

This is even after a server restart / application restart?

If I restart Railo, then it works again.  But just refreshing the browser
doesn't make any difference.

OIC - you get it occasionally.

The issue with Railo later versions is that is happens occasionally.

If you get the error, just re-init your app, it should recreate anything
that is missing. You shouldn't have to restart the whole server (unless
there are further bugs in Railo, but I've not seen them in my unit tests).

That should have read

Yeah, that's correct.  It works for a while then it comes up...I guess I
could do "try/catch" on that code and then reinitialize the app, but really
its something I have to resolve because the reset causes people to get
logged out etc, the way we have it configured right now.  I am going to
switch to the stable version of ColdSpring asap.

So are you saying that on a production app you are getting the error?

I've only ever seen it very rarely on ACF, and then only in development.

Its actually more of a beta, but yeah.  I have only tried this app on Railo
so far.  Its kind of unpredictable when its going to occur.  Sometimes the
app works for hours without ever seeing that Singleton error, and sometimes
it only lasts for a few minutes.  I don't really know what it could be,
maybe some sort of issue with concurrent users.
