Not allow subtopics Exception

Question

Hi,
I'm receiving an Exception while sending a message to a specific subtopic with blazeds.
"msg.setHeader(AsyncMessage.SUBTOPIC_HEADER_NAME, "mySubtopic");" gives the following exception and I have search on this exception and cannot find a solution.
So how can i handle this exception?
Exception in thread "Thread-10" flex.messaging.services.ServiceException: Attempt to subscribe or unsubscribe to the subtopic, 'mySubtopic', on destination, 'BlazeDsServicePush', that does not allow subtopics failed.

Hi,
Did you setup your destination to accept subtopics ?
For example
<destination id="chat">
        <adapter ref="chatAdapter"/>
        <properties>
            <network>
                <session-timeout>0</session-timeout>
                <throttle-inbound policy="ERROR" max-frequency="50"/>
                <throttle-outbound policy="REPLACE" max-frequency="500"/>
            </network>
            <server>
                <allow-subtopics>true</allow-subtopics>
                <subtopic-separator>.</subtopic-separator>
                <max-cache-size>1000</max-cache-size>
                <message-time-to-live>0</message-time-to-live>
                <durable>true</durable>
            </server>
        </properties>
        <channels>
            <channel ref="my-streaming-amf"/>
        </channels>
    </destination>
