But my service is inside some package that some bundle exports,
so if I stop bundle serice is gone and also package is gone,
I don't understand how service can go without package.
and how can I have two services with same name that don't come
from two different packages.
Can you tell me if you know some good example for this on the web?
________________________________
Services are more dynamic than packages; they can come and go at will,
package wiring cannot. Once a bundle is wired to a given package, it
will not wire to another provider until the framework is refreshed.
Performing an update is not sufficient. You must always refresh the
framework to cause any rewiring.
