Re: [riena-dev] Remote Services from updated Configurations of Managed S

[Christian Campo <christian.campo@xxxxxxxxxxxx>]

Hi Ekke,

I think this is a misconception about what properties are and what  
configuration is. Properties is a dictionary of key value pairs  
associated with that service. Configurations are also key values pairs  
but they are not the same (semantic wise) as the service properties.

In your example Service X (or better Instance X) is registered with  
Interface A. Now the same instance X also registers with Interface  
ManagedService. These two have no relationship (even though they are  
two registeration about the same instance).

Instance X registered with Interface A can have a set of Properties,  
which I believe are immutable. So you cant chance the properties of a  
registered service. You can change its configuration, but these are  
two things.

My recommendation. Register your Instance X with the Interface  
ManagedService. As soon as you get the configuration through the  
ManagedService interface, the instance itself registers itself with  
Interface A and with the set of properties it receives. For each and  
every update of the configuration you unregister and register again.

that should work

p.s. And right we monitor Service Register and Unregister Events. I  
believe there are no events for property changes which make we think  
they are immutables.
