Thank you very much for the feedback on this bug trace. From this point,
the KF team should proceed by their part of investigation, shouldn't they?
Thank you once more
My very best regards,
Aggelos Mpimpoudis

Hi Aggelos,
Peter Kriens very kindly did some investigations into this problem,
and the current thinking is that it could be a bug in Knopflerfish.
At this stage I have not heard any confirmation, but if you read the
following Equinox bug report then you'll be up to speed:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=200915
Pending a fix to Knopflerfish it would be interesting to try out SAT
once more.
Thanks
Simon

Re: [osgi-dev] Service Tracking Matter
I have done exactly what you have told me to, the last days. I followed
the documentation, and did everything with Customer-Vendor Tutorial in
hands, but I cannot find a proper walkthrought to a solution. This fact
makes me think, that maybe we have a bug, in SAT vs Knopflerfish. So,
when my bundle (using SAT), executes it's deactivate method (after the
lose of some needed service), when it comes to re-execute my activate
method (after a re-registration of the previously lost service) my
bundle doesn't do anything at all!!!!!!! It doesn't execute it's
activate method for second time and all registered interfaces are
de-registered. Why??? SAT is monitoring the registry in a constant
manner, isn't it??? :-( :-(
The project I am working on, is a very large scale project on pervasive
computing, and a toolkit like this would be exactly what we need... :-(
:-( ( I would like to see equinox on this, but this very difficult the
moment we speak... )
