Hari, Yes, I am familiar with singletons. As a mtter ofr fact, the class that I am creating is going to be a singleton - which is why I don't want to construct it with a context.
So your suggestion is that I extend the Application class using the singleton pattern? And my extension saves 'this' (the context) as a static member of my singleton? So now I have to see how to extend the application class. Thanks. ...Jake >>>>> "HE" == Hari Edo <[email protected]> writes: HE> One alternative is to look for, or create, a public singleton.
