Thomas Watson commented on FELIX-5356:
--------------------------------------

Yes, that is the approach I was going to use.  Basically just ignore factory 
configurations for factory components, otherwise the rest of the code/behavior 
with respect to singleton configuration stays the same.

> Component Factory and CM factory Configurations behave badly

>             Project: Felix
>          Issue Type: Bug
>          Components: Declarative Services (SCR)
>    Affects Versions: scr-2.0.6
>         Environment: All
>            Reporter: Thomas Watson
>            Priority: Minor
>
> 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.
