[Opensource] MessageBundle for a given schema?

[larry hamel]

hi,

below is an old post by Daryl about MessageBundles outside of the Expresso schema.  

I'm having the same problem with 4.1ea-2 code.  

Was there some advice about this?  Only the Expresso message bundle is accessed, as far as we can tell, for DB object descriptions.

thanks,

larry

I don't want to code setSchema("intro.IntroSchema") in the CompanyController (high coupling; what if I want to use it with another schema?). If IntroSchema's constructor was being called, would the "addController("intro.controller.CompanyController")"
