Stomp messages don't preserve property types: please document this behaviour
----------------------------------------------------------------------------

                 Key: AMQCPP-32
                 URL: https://issues.apache.org/activemq/browse/AMQCPP-32
             Project: ActiveMQ C++ Client
          Issue Type: Wish
          Components: Stomp
    Affects Versions: 1.1
            Reporter: Albert Strasheim
         Assigned To: Nathan Mittler


I am producing messages from Java and C++ using ActiveMQ and AMQCPP, respectively. Messages
I produce have an int property set on them which I want to select on, again in Java or C++.

As far as I can tell from the [Stomp Protocol specification|http://stomp.codehaus.org/Protocol]
there is no way to specify the types of message headers. As a result, all the messages end
up with String properties as can be be seen in the unmarshal method of [org.apache.activemq.transport.stomp|http://svn.apache.org/viewvc/incubator/activemq/trunk/activemq-core/src/main/java/org/apache/activemq/transport/stomp/StompWireFormat.java?revision=470398&view=markup].

I can work around this problem by selecting on id=123||id='123' in both Java and C++, but
it seems a bit suboptimal.

At least, this issue should be documented somewhere in activemq::connector::stomp::commands::StompMessage
to help other people who can't figure out why their selectors don't work.

We could consider adding a function that allows the user to specify that Stomp message properties
should be sent in a type safe manner, and then prepend some kind of string to the property
name to indicate the type. StompWireFormat on the Java side could check for this case and
set the typed properties accordingly. This is probably too much of a hack -- people who want
typed properties to work right can use Openwire in the (hopefully) near future.
