By the way - a bit more info I've worked out here..
The error occurs if I try to send multiple messages using the same
reply-to temporary address.
ie. Something like this:
SEND
destination:/some/where
reply-to:/temp-queue/foo
SEND
destination:/some/where/else
reply-to:/temp-queue/foo
Is that meant to work or not?
I realise it's not quite the intended use of the /temp-queue/
functionality, but I thought it would be OK.
If I change the above to send to /temp-queue/foo1 and then
/temp-queue/foo2 it all works as expected.
I've changed my code to result in something like this instead:
SUBSCRIBE
destination:/exchange/amq.direct/${unique_id}
SEND
destination:/some/where
reply-to:/exchange/amq.direct/${unique_id}
SEND
destination:/some/where/else
reply-to:/exchange/amq.direct/${unique_id}
As this has the desired effect of receiving messages just to me, and
disposing of the messages if I've disappeared.
However, I thought the "processing error" might still be a bug in Rabbit?

I've hit another issue with the temp-queue/reply-queue functionality in
rabbitmq's stomp adapter.
I basically just wrote a couple of little apps that ping a message back
and forth between each other, using the /temp-queue stuff in the
reply-to fields.
The first message goes through, but after that the server kicks me off,
and reports:
=ERROR REPORT==== 10-Nov-2011::04:25:53 ===
STOMP error frame sent:
Message: "Processing error"
Detail: "Processing error\n"
Server private detail: {badarg,
[{erlang,list_to_binary,
[<<"amq.gen-X4QkaphR9pZCvDYz5aNXKg==">>]},
{rabbit_stomp_frame,binary_header,2},
{rabbit_stomp_frame,binary_header,3},
{rabbit_stomp_util,message_properties,1},
{rabbit_stomp_processor,do_send,4},
{rabbit_stomp_processor,process_request,3},
{gen_server2,handle_msg,2},
{proc_lib,wake_up,3}]}
I'm pretty sure I'm sending valid messages to the server, so I'm not
sure what's going on here.
Any thoughts?
Thanks,
Toby
