Re: Controller settings and process groups

Uwe,

Services defined in the Controller Settings are available to Reporting
Tasks and other services defined there. Services defined within a Process
Group are available to descendent components. To create a service that is
available to all components in the flow, define it in the root Process
Group.

Uwe,

The User Guide was updated in version 1.3.0 to better describe how controller settings are scoped.
