Re: logging from a helper

Your words describe my thoughts much better!  that was the issue I
thought was happening, but I'm very "green" to Avalon.  This is nothing
big, and I would much rather see the build changes stable!  They sound
very promising.

I'd looked at trying to pass in the logger, and looks like it would have
to be done in all the implementations at the getHelper method for
DefaultPersistent.  but again, i probably don't know what i'm talking
about.

Maybe I'll just add this as a feature request for the future, but thank
you very much for looking at it.

Therefore even though it might implement the lifecycle interface (enableLogging), the method won't get called, as the class is instantiated from a Persistent, not by the Container itself.
