We've got 2 different services with the same endpoint name (and different services and interfaces of course). If we want to monitore them, we have to choose from the endpoint name today (unfortunately, we can't choose from the service QName and or the interface QName, even we can monitore on further...). But into the List Box (see the screenshot), if we choose the first or the second endpoint name (they're equals!), it allways choose the second.
To reproduce, it's simple :put 2 JBI endpoints with the same endpoint name, and try to monitore the 2 together.
