[kepler-dev] SSH Directory List

[Norbert Podhorszki]

Hi Frederico,

You have to send a token to the "trigger" input port of the
SSH Directory Listing. This is the black colored port.
The other three (gray) are optional parameter ports, which means you can
deliver the required information to the actor either in a token (as you do 
for "target" and "dir") or as a parameter (as you do for "mask").

The error message here tells you that the error is with the "trigger" port
of the SSH Directory Listing actor, which tried to read a token 
/IOPort.get()/ but that port was not connected at all (channel width is 
0).

You may argue that the actor could that find out itself, though...

Best regards
