Hi all, We're trying to migrate our application from Knopflerfish to Felix at the moment. It's almost working, but we've had a lot of problems with the following exception:
INFO ERROR: EventDispatcher: Error during dispatch. (java.lang.IllegalStateException: Cannot get the Service Registration, owned by Thread[SCR Component Actor,5,main]) WARN java.lang.IllegalStateException: Cannot get the Service Registration, owned by Thread[SCR Component Actor,5,main] WARN at org.apache.felix.scr.impl.AbstractComponentManager.lockServiceRegistration(AbstractComponentManager.java:782) WARN at org.apache.felix.scr.impl.AbstractComponentManager.unregisterComponentService(AbstractComponentManager.java:709) WARN at org.apache.felix.scr.impl.AbstractComponentManager.deactivateInternal(AbstractComponentManager.java:549) WARN at org.apache.felix.scr.impl.AbstractComponentManager.deactivate(AbstractComponentManager.java:238) WARN at org.apache.felix.scr.impl.AbstractComponentManager.reactivate(AbstractComponentManager.java:171) WARN at org.apache.felix.scr.impl.DependencyManager.serviceAdded(DependencyManager.java:181) WARN at org.apache.felix.scr.impl.DependencyManager.serviceChanged(DependencyManager.java:115) WARN at org.apache.felix.framework.util.EventDispatcher.invokeServiceListenerCallback(EventDispatcher.java:765) This seems to have been fixed in FELIX-550. However we're still seeing it, and it seems to be a problem with static references in factory components which have a target specified. What seems to happen is when the factory component is created, the DependencyManager correctly has the m_target field set. However, when the component is activated, the getProperties() method in ComponentFactoryImpl doesn't add the properties for the target attributes of references as ImmediateComponentManager does. Then, when setTargetFilter on the DependencyManager is called, its target parameter is null (because the property isn't correctly set) and the SCR interprets this as a change in the target. Since the reference is static, the component is deactivated and reactivated incorrectly. As far as I can tell, the incorrect part is that the reference target properties are not set for factory components. I can't see anything in 112.6 of the spec which would imply this should not happen. I guess the fix would be to set those properties in the ComponentFactoryImpl as it's done in the ImmediateComponentManager? Cheers, Colin
