late static optional references not injected
I have a component with a reference as follows:
@Reference(name="globalMenuItemsProvider",
cardinality=ReferenceCardinality.OPTIONAL_MULTIPLE,
policy=ReferencePolicy.STATIC,
referenceInterface=GlobalMenuItemsProvider.class)
with scr 1.0.6 every service of that interface got injected (and the
component deactivated and reactivated), with scr 1.4.0 the component only
gets the services available when it is activated, services showing up later
are ignored.
I was expecting the behavior as provided by 1.0.6. I've also tried
1.4.1-SNAPSHOT with the same results.
Cheers,
reto

Hi Felix,
thanks for the info, yes 1.4.1-SNAPSHOT behaves the same as 1.4.0, sorry for
the unclear phrasing.
Cheers,

Yes, this is correct.
The problem is, that the 1.0.6 behaviour is incorrect because newly
registered services must not be provided to statically bound references
once the component is activated.
If you want get updates on newly arriving services after the component
has been activated, you have to declare them as dynamic references.

I assume you mean 1.4.1-SNAPSHOT has the same behaviour as 1.0.4, right ?
