Re: [Orocos-users] back to rttlua again

Just debugged into it, it seems that the operation call isActive failed 
itself.

in the OCL lib i added some debug output to the c++ part lua/rtt.cpp in 
function TaskContext_getState

The code get's called and returns normally.
Also in the case section my printf's were written.
So it seems that the results were not padded correctly back to LUA?
Since i'm new to LUA i getting stucked again.
