multiple senders in one container

[Louis Letourneau]

I am using qpid proton 0.29 python talking to Active MQ using AMQP 1.0

I am trying to use one container and send messages to multiple queues

    def on_start(self, event):
        conn_url1 = Url(...)
        self.sender1 = event.container.create_sender(conn_url1)
        conn_url2 = Url(...)
        self.sender2 = event.container.create_sender(conn_url2)

    def on_new_data(self, event):
        msg = Message(body=event.subject)
        print('{}, {}'.format(self.sender1.credit, self.sender2.credit))
        if(self.sender1.credit > 0):
            self.sender1.send(msg)
        else:
            print("No credits: sender1")
        if(self.sender2.credit > 0):
            self.sender2.send(msg)
        else:
            print("No credits: sender2")


Problem is, sender2 always has 0 credits.
If I create X senders, only the first one created will have credits the
others will always be 0

I only found 2 ways to make this work.
1- Not use containers, but use a BlockingConnection per sender
2- Create one container per sender. Which means many loops, basically one
per connection

Is this normal? Why can't a container manage multiple connections/senders?

Thank you
