Event Loop neither Terminates nor reconnects when connection breaks

Hi,
I am starting using Autobahn-Python.
maybe this is a noob-problem. I did the following (based on the example code):

1. started a router
2. started a callee process offering some rpcs
3. started a caller, called the rpcs

all works fine.

problem:
if the connection to the router goes down, the callee side shows a warning "WAMP transport was lost before closing"
Then it does not terminate and also does not attempt to reconnect

I tried with both: asyncio and twisted implementations because someone said that twisted would reconnect. But also there: Error is detected and logged, but event-loop does not terminate and als no re-connect. This questions my whole concept (one weekend of work).

What does help terminating the loop is:

    async def onDisconnect(self):
        loop = asyncio.get_running_loop()
        loop.stop()

is this the way to go?

There still is a problem when initial connection to WAMP Router works but registration does not (because router is currently coming up for example). In that case, the callee system hangs forever. Is there a solution for that?

Reproduce the example router, callee, and caller setup with both asyncio and Twisted, including a dropped router connection and a registration attempted during router startup. Read the connection lifecycle around the shown onDisconnect handler and compare the observed event-loop behavior with the expected termination or reconnection behavior. Done means both failure cases have a documented, verified outcome.
