Alexander Broekhuis commented on FELIX-6161:
--------------------------------------------
Hi guys,
I'm curious about this issue, is there already a fix? I do miss the filter info
on my listenerhook, and need it for my solution.
Many thanks!

> Project: Felix

> When experimenting with creating a Service ListenerHook to realise a
> [providing a service on demand
> pattern|https://osgi.org/specification/osgi.core/7.0.0/framework.servicehooks.html#d0e45721],
> I noticed that references from components managed by Felix SCR were not
> showing up as expected: When a reference declares a target filter, that
> target filter is not included in the ListenerInfo provided to the
> ListenerHook. As a consequence the ListenerHook is unable to create a
> matching service.
> Source of the observed behaviour is how SCR tracks references, specifically
> that it opens a ServiceListener for just the className and performs the
> matching of the target filter inside the ServiceListener. This approach
> unfortunately hides the target filter from the Service ListenerHook and thus
> the Service ListenerHook will have insufficient information to create a
> matching service.
> Also look at the discussion on the dev mailing list:
