[Rock-dev] Multiple services of same type in tasks and data_service_type

[Christian Rauch]

Hi,

if a task provides multiple services of the same type with different 
alias, how do I select one particular service by name in my profile?

In my case a task provides two different Base::<type>ControlledSystemSrv 
and syskit tells me:
{{{
= there is an ambiguity while looking for a service of type 
Base::ControlledSystemSrv in Motionproxy::Task
| candidates are:
|   controlled_system,
|   motion_sample_consumer
}}}

How do I select one of the candidates when I want to fulfil 
'controlled_system' of a ControlLoop?

A similar problem arises when a data_service_type also provides two 
different Base::<type>ControlledSystemSrv as both have the output port 
"command_out" but different type.
Is there a way to rename the ports of a service in the provides statement?

Regards,
Christian
