Timothy Ward commented on FELIX-5248: ------------------------------------- Hi David, The component is immediate and has a configuration policy of required. It has one static reference to a service which is satisfied, an activate method which takes a bundle context, a type safe configuration object, and a map of the raw configuration. It also has a deactivate method which takes no arguments. The failure flow is as follows: 1. The component's bundle is started and the referenced service is available. The configuration requirement correctly prevents activation of any component instances. 2. A factory configuration is created for the correct factory pid with some config properties. Occasionally one of the config properties is malformed, which the component instance detects, throwing an exception from the activate method. This correctly prevents that component instance from starting when the config is bad. 3. The factory configuration is then updated by the user to correct the malformed config property. At this point I do not get the behaviour I expect. I expect a component instance to be activated with the updated configuration. Instead the component sits there, ignoring the configuration update. If at this point I disable and enable the component then everything works fine, but I don't want to do that as it will disable all of the other instances created by other factory configurations. It also works if I delete the old config and create a new config, but I don't want to do that either because it's an extra set of steps for the user. I don't think that what I'm asking for is illogical, although I can't find a line in the specification which says that it must work. I hope this helps. I've tried looking through the felix SCR unit tests, but at the moment I'm not entirely sure how I would write a failing test for this behaviour.
