>             Project: Felix
>          Issue Type: Bug
>          Components: Declarative Services (SCR)
>    Affects Versions: scr-1.2.0,  scr-1.4.0
>            Reporter: Felix Meschberger
>            Assignee: Felix Meschberger
>             Fix For:  scr-1.4.2
>
>
> In earlier versions of the Declarative Services implementation, configuration 
> for the components has been provided by the Declarative Services bundle 
> registering ManagedService[Factory] services for each component registered. 
> This ensured configuration to be provided by Configuration Admin service to 
> the components once Configuration Admin service is active, configuration is 
> present and a Component is here to take it.
> The drawback is, that this mechanism operates completely asynchronous 
> (potentially causing components to be cycled during fire-up). Thus 
> Configuration is now provided to the Components by the Declarative Services 
> implementation by asking the Configuration Admin service for configuration on 
> behalf of the components. Configuration updates are forwarded by the DS 
> registering a ConfigurationListener.
> The problem now is, if Declarative Services is started (and has set up 
> Components) before the Configuration Admin service is present, configuration 
> will never be provided to components.
> To fix this, Declarative Services should register for service events to hear 
> when Configuration Admin becomes present to be able to forward any 
> configuration to the components.
