>          Issue Type: Bug
>          Components: Declarative Services (SCR)
>    Affects Versions: scr-2.0.6

> This is a corner case and a minor issue in my opinion.  The specification really only mentions the following with respect to what should happen with factory components and CM factory configurations:
> {quote}
> A factory configuration must not be used if the component is a factory component. This is because SCR is not free to create component configurations as necessary to support multiple Configurations. When SCR detects this condition, it must log an error message with the Log Service,
> if present, and ignore the component description.
> {quote}
> At face value it seems to suggest that any CM factory configurations must be ignored when they match the factory component PID.  But the last sentence also makes a strong assertion that the component description must be ignored if matching factory configurations are detected while discovering a factory component description.  This seems overkill to me.  Why not just ignore the factory configurations?  Why must the factory component description be ignored altogether?
> The other issue is that if a matching factory configuration is created later, after a ComponentFactory has been registered and a ComponentInstance has been created (with newInstance) then felix SCR will dispose of the ComponentInstance.  In this case the component instance did not specify an update method.
