>                 Key: DISPATCH-195
>                 URL: https://issues.apache.org/jira/browse/DISPATCH-195
>             Project: Qpid Dispatch
>          Issue Type: Bug
>          Components: Routing Engine
>    Affects Versions: 0.5
>         Environment: Linux
>            Reporter: linuxta

> The proton example fails with a router error:
> https://github.com/apache/qpid-proton/blob/master/examples/python/tx_send.py#L41
> #41  self.container.declare_transaction(self.conn, handler=self)
> When the client declares a transaction at start, proton library sends out a 
> control message that gets rejected by the router. This happens before the 
> client sends out any regular message within the transaction.
> Error Messages from router:
> ERROR (error) Invalid message: Invalid body value
> ERROR (error) Invalid message: Invalid body value
> MESSAGE (trace) Sending Message{} on link txn-ctrl  
> The message format in the body of the control message is not accepted by the 
> router.   The body has a structure:
> body=Described(symbol(u'amqp:declare:list'), [None])
> Apparently, transactionall messages are not supported by the router.
