Sorry for delay in responding; it's hard to pick out the HiveMind stuff in this list; I need to add a filter.

It is possible to get to the registry indirectly, by implementing Initializable. The ServiceExtensionPoint includes a module property, which includes a registry property, from which you can get anything. However, that's not the ideal way; if you need (or may need) another service, create a property for the service and have the hivemind.BuilderFactory assign the other service as a property of your implementation. The latest releases of HiveMind will create a deferred proxy to the service (so that you don't incur the overhead of constructing the service until you actually invoke a method on the service). > > Therefore I want to suggest that from the > Initilizable.initializeService() > parameters there would be a way to get the Registry instance > which acutally > manages the Service.

Yep, getModule() is already in there, in GenericExtensionPoint (super-interface of ServiceExtensionPoint). -- Howard M.
