Description

This is related to this thread in the mailing list:

http://karaf.922171.n3.nabble.com/Updating-Managed-Service-Factory-Config-Via-quot-config-quot-commands-td4028322.html#a4028325

In summary, it does not appear to be possible to update a factory configuration not backed by a file (e.g. one created via a karaf feature file).

If I have a configuration like this:

Pid: com.mycompany.myservice.327d4cd4-4704-4190-9e51-26f5f0b91435
FactoryPid: com.mycompany.myservice
BundleLocation: mvn:com.mycompany/mycompany/1.0.0-SNAPSHOT
Properties:
myservice.host = 0.0.0.0
myservice.port = 8080
org.apache.karaf.features.configKey = com.mycompany.myservice-healthcheck
service.factoryPid = com.mycompany.myservice
service.pid = com.mycompany.myservice.327d4cd4-4704-4190-9e51-26f5f0b91435

and try to edit the configuration. e.g.:

config:edit com.mycompany.myservice-healthcheck
config:propset myservice.port = 8081
config:update

I get a new config:

Pid: com.mycompany.myservice.8cbfea87-f66e-44b4-b94a-11fdb14c235f
FactoryPid: com.mycompany.myservice
BundleLocation: mvn:com.antennasoftware/gravity.clientAP.blueprint/1.0.0-SNAPSHOT
Properties:
service.pid = com.mycompany.myservice.8cbfea87-f66e-44b4-b94a-11fdb14c235f
myservice.port = 8081
service.factoryPid = com.mycompany.myservice
felix.fileinstall.filename = file:/home/karaf/apache-karaf-2.3.1/etc/com.mycompany.myservice-healthcheck.cfg

If I go and specify the pid exactly:

> config:edit com.mycompany.myservice.327d4cd4-4704-4190-9e51-26f5f0b91435
> config:propset myservice.port 8081
> config:update

Nothing happens.

If I try the "-f" option (which I understand should create a file) I get a NullPointerException:
