problem with nullPointerExceptions

I have a primary onException function setup in my main.cfc handler that is defined in Coldbox.cfc.

I then wrapped the function with a try catch

and I still get random NullPointerExceptions

does anyone have any insite why this is happening. It works 98% of the time perfectly. about 2% of the time it throw an error.

Looks like it might be a Railo bug. Have you tried asking them by chance?

Thanks!

Also, if the error always happens in CacheBoxProvider.cfc, have you tried putting any temporary error handling in there? I’m not familiar with Railo, but the last thing in the stack trace is Caster.toPageException() which looks like it was trying to handle an exception when the NPE occurred. Unless, of course, the NPE WAS the original exception.
