Hi,

i'm using the following code to get a pointer to a command that is added to a
TaskContext by exporting a function in a program-script:

c++:(line 63 of CommandListener.cpp)

RTT::DispatchInterface* moveJS;
moveJS=this->getPeer("SuperVisor")->commands()->
getCommand,double)>("moveJS");

programscript:

export function moveJS(array pos, double t)
{
do stuff
}

the taskbrowser shows me the available command:
In Task SuperVisor[R]. (Status of last Command : none )
(type 'ls' for context info) :ls

Listing TaskContext SuperVisor :

Configuration Properties: (none)

Execution Interface:
Attributes : (none)
Methods : cleanup configure isConfigured isRunning start stop trigger
update
Commands : moveCS moveJS
Events : (none)

Data Flow Ports: (none)

gdb gives me:

Program received signal SIGSEGV, Segmentation fault.
