DataSource null in ReceiveStream and NewReceiveStreamEvent never called

Question

Hi,
in a ReceiveStreamListener.update(ReceiveStreamEvent evt) implementation, when evt is instanceof StreamMappedEvent, the receiveStream.getDataSource() return null. Why?
p.s.
StreamMappedEvent is the only evt type called. No NewReceiveStreamEvent

Thanks for input, but no solution yet.
If you haven't received a NewReceiveStreamEvent then I suspect you are setting the receive stream listener too late into your processing and thus missing that event.I don't think that's the cause, this is what I do:
1) Init server RTPManager
2) Add ReceiveStreamListener to client RTPManager
3) Init client RTPManager
4) Add server target to client
5) Add client target to server
6) Server createSendStream
The StreamMappedEvent occurs when there is an orphaned receive stream. In other words there are no participants in the receive stream. What can I do to verify that?
Are you getting the receive stream from the StreamMappedEvent.getReceiveStream() method and then looking for a DataSource -- or from the new Participant?I use receiveStream.getDataSource(), as used in AVReceive2
Documentation would suggest that the Participant be used to get the receive stream. However, I don't have any real world experience in doing this. participant.getStreams() is empty
If you have any other idea, please update.
bye
