Declarative Services, determining reference satisfaction with target services
I have a factory component (call it ComponentA) with a service reference
(call it X). The service reference X has an interface of Y and a target
of "(name=Z)"
If a service is registered with an interface of Y, but a name service
property of something other than Z, I would expect the service reference
X to not be satisfied. However, using Felix SCR, I'm seeing that the
reference is satisfied. When I go to create an instance with the
factory, I then get a ComponentException saying the dependency is not
satisfied.

RE: Declarative Services, determining reference satisfaction with target services
Posted by Da...@L-3Com.com.
I looked at the issue and see that the fix is undesirable. Perhaps I
should send something to the OSGi mailing list but it seems like this
issue should be better explained in the specification.
Is there a good way then to check or wait for the component instance to
be satisfied?

Hi David,
Indeed I have also reproduce the problem you are describing.
I think I have a working patch; so I will create a JIRA issue and will
attach the patch to it.
kind regards;

RE: Declarative Services, determining reference satisfaction with target services
Posted by Da...@L-3Com.com.
It looks like part of the problem is that the ComponentFactoryImpl
doesn't look at the target service properties for some reason so it
accepts services even if the target doesn't match. When the component
instance is created, the ComponentFactoryNewInstance does check the
target properties so the instantiation fails.
I think this is a bug.

I have a factory component (call it ComponentA) with a service reference
(call it X). The service reference X has an interface of Y and a target
of "(name=Z)"
If a service is registered with an interface of Y, but a name service
property of something other than Z, I would expect the service reference
X to not be satisfied. However, using Felix SCR, I'm seeing that the
reference is satisfied. When I go to create an instance with the
