RE: [cosmos-dev] problemwithusingautowireandComposableManagedCapabilityS

["Hawkins, Joel" <Joel.Hawkins@xxxxxxxxxxxxx>]

Hubert, I’ve fixed the classloader problem (thanks for finding that one!), but your real issue is caused by listening only for the contribution manager, and not the WSDM binding. You’re registering your class prior to the WSDM binding being available, so the autowire can’t provide you the binding because it doesn’t exist yet.

If you use declarative services, this is an easy issue to resolve. If you want to do it programmatically, you’ll need to listen for the WSDM binding service, and then resolve the contribution manager. This is safe, however, since the WSDM binding service doesn’t get created until the contribution manager is available.

If this isn’t clear, let me know and I’ll try and elaborate. If you’d like, I could also make the required code changes for you, but you can probably do that every bit as fast as I can!

Cheers

The program fails at line 193 of org.eclipse.cosmos.me.management.common.util.ManagementProxyFactory.  Here is the stacktrace:
