[Rock-dev] Deploy task multiple times with the default deployment

[Christian Rauch]

Hello,

I want to use a task (Monitor::Task) multiple times, so I defined the 
aliases in the config/* of the robot, e.g.:
{{{
Syskit.conf.use_deployment Monitor::Task => 'monitor1'
Syskit.conf.use_deployment Monitor::Task => 'monitor2'
}}}

These tasks are then used by:
{{{
define 'mon1', Monitor::Task.use_deployments('monitor1')
define 'mon2', Monitor::Task.use_deployments('monitor2')
}}}

When calling both definitions (mon1, mon2) after each other, I expect 
that there will be two Monitor::Task with their corresponding name.

When starting the second monitor the deploying fails with:
{{{
Syskit[FATAL]: cannot deploy the following tasks
Syskit[FATAL]: Monitor::Task:0x3f2eb28{conf => [default]}[]
Syskit[FATAL]:
Syskit[FATAL]: Monitor::Task:0x3f2eb28{conf => [default]}[]: multiple 
possible deployments, choose one with #use_deployments(deployed_task_name)
Syskit[FATAL]:   task monitor2 from deployment 
orogen_default_monitor__Task defined in monitor on localhost
Syskit[FATAL]:   task monitor1 from deployment 
orogen_default_monitor__Task defined in monitor on localhost
}}}

which is misleading, as the task to deploy is already defined via 
#.use_deployments.

Is there something similar to the renaming feature when starting orogen 
components, that is also applicable within syskit, i.e. starting the 
default deployment twice with different names?

Regards,
Christian
