You didn't run this, did you? It should be "CCL::MinokHandler"

It doesn't work because scripting is not aware of the type
"MinokHandler". So for you script to work you need to write a typekit
for this type and define a method to retrieve such a type. A quicker
(and dirtier) solution would be to modify addCheckedPeer accept a
string peer name. In the implementation you would then run
this->getPeer to get the actual TaskContext handle. For that to work
you would need to add the peer first, too.

I don't quite understand what the problem is. Why can't you add the
t_handler? Can you give some more details?

Markus

I have a program.ops file as follows 

import("oro_minok_handler")
import("rtt_std_msgs")

loadComponent("t_handler1",CCL::MinokHandler)
loadComponent("t_supervisor",CCL::MinokSupervisor)

loadService("t_handler1","marshalling")
t_handler1.marshalling.readProperties("confFile1.cpf")

setActivity("t_handler1",0.001)

loadService("t_handler2","marshalling")
t_handler2.marshalling.readProperties("confFile2.cpf")

setActivity("t_handler2",0.001)

t_supervisor.addCheckedPeer("t_handler1")

And it gives me an error saying wrong type of argument provided in "this.addCheckedPeer" expected type MinokHandler *, got type string. 
If I had to hard code the same functionality in a main.cpp, I would do it as

MinokSupervisor t_supervisor("Supervisor");

MinokHandler  t_handler1("t_handler1");

MinokHandler  t_handler2("t_handler2");

....

t_supervisor.addCheckedPeer(&t_handler1);
t_supervisor.addCheckedPeer(&t_handler2);
 

So My question is how can I do the same thing in scripts. 
Thanks Markus
