Durable flag on my topic consumer doesn't work? - jms

Question

trying to implement the Durable feature on a Topic consumer.
Placed a name to the jms consumer and also clientID. (Obviously added the durable="true")
Now as far as i've read. The Topic will register the consumer as "durable" when it gets running for the first time.
So basically i did this, deployed the producer and consumer. It gets registered as a durable consumer. Publish a message to the topic, the consumer gets it. Now i undeploy the consumer and publish another message the consumer should be receive whenever gets up. When I deploy the consumer again, i get the common temp-topic://XXXXXXXXXXXX destination doesn't exist.
Why is this happening? Shouldn't i be getting the "lost" message?
This is my current jms activemq connector configuration for the publisher:

This is one of the consumers, i got 2, but both are basically the same thing

Durable Messaging is a little tricky in JMS, as your config/code will have to meet several criteria to get this to work correctly:
enable persistence in your broker's config (in ActiveMQ this is either done in the connection string as David posted, or in your configuration xml
create a durable subscriber (ActiveMQ API)
I'm not sure that mule creates durable subscribers. However, you can check that in ActiveMQ's web console. There you can get a list of the current durable subscriptions.
