I don’t think it is necessary to use the SingletonEnforcer method, but I thought after a bit of reading that it is the suggested way to go.

Thanks for having a read – and I can never remember anything at the best of times, so popping it up here helps me. I’m pleased it’s been useful for you too

Thanks for your post, I have used this method before but couldn’t remember the syntax.

Have you got any idea why the Cairngorm examples are broken? They don’t use the enforcer???
