Ivo Ladage - van Doorn commented on AMDATU-174:
-----------------------------------------------
I'm able to reproduce the issue right now! This time it appears in the
FriendsGadgetServiceImpl, with this pseudo code:
private String m_hostname;
private String m_portnr;
public void init() {
// now m_hostname and m_portnr are null
}
public void updated(Dictionary dictionary) throws ConfigurationException {
if (dictionary != null) {
checkAvailability(dictionary, new String[] {HOSTNAME, PORTNR});
m_hostname = (String) dictionary.get(HOSTNAME);
m_portnr = (String) dictionary.get(PORTNR);
}
}
And in the Activator:
Component friendsgadgetService = createComponent()
.setInterface(ResourceProvider.class.getName(), null)
.setImplementation(FriendsGadgetServiceImpl.class)
.add(createServiceDependency().setService(LogService.class).setRequired(true))
.add(createServiceDependency().setService(GadgetManagement.class).setRequired(true))
.add(createServiceDependency().setService(HttpContextServiceFactory.class).setRequired(true))
.add(createServiceDependency().setService(HttpService.class).setRequired(true))
.add(createConfigurationDependency().setPid(FriendsGadgetServiceImpl.PID));
Added a breakpoint to updated() and init() methods. updated() is never invoked.
Now the Friends gadget is contained by bundle 1
I update however bundle 10, which holds the gadget management service on which
the gadget has a dependency
When updating bundle 10, init() is invoked but updated() is not
However, when I update bundle 1 updated() is invoked!
So it seems that updated() of service A contained by bundle A is not invoked
when bundle B is updated holding a service B on which service A depends.
> Investigate the ManagedService.updated() method call not always being invoked
> for required configuration dependencies.

> Reporter: Marcel Offermans

>
> Several reports have indicated that sometimes the updated() method is not
> invoked before a component with a required configuration dependency is
> initialized. This does not yet seem reproducable, but is worth investigating
> because it can lead to all kinds of problems. If it is indeed a bug, it needs
> to be resolved in the Dependency Manager.
