Thanks for your precise answer.
In your proposal I note that I could perhaps do the read somewhere else than
in the initializeComplete() ?
If their is a more natural way to read the filterTopic I can do it... I'm
just in lack of some code sample which could help me in this progress.
I can also overwrite the SimpleSubscriptionManager but again the lack of
code sample is blocking me. Can I do that starting from the wsn-producer ?
Do you have a code sample I could re-use to do that ?
Thanks for your help
Cheers
