In general, it shouldn't be a problem to mix and match Cayenne objects with other object types. The integration tries hard to distinguish between objects it should analyze in a cayenne-specific manner, and those that should just pass through.
Just looked at the line of code and at the point of failure. I'm guessing that you're calling "resources.getContainerMessages()" from inside a page class? If that's the case, just use resources.getMessages(). getContainerMessages() is useful for component building, if you have a component that is building an model from an object passed to it by its parent, and you want to be able to override the defaults in the parent's messages. But a page has no parent, so getContainerMessages() is null.
