[kepler-dev] File exists? actor

[Norbert Podhorszki]

Hi,
directory listing throws an exception if the directory does not exist.
I need just a true or false so I can branch in the worfklow.

Ilkay,
The FileExist expression: I've never heard about this. I know only about 
the String methods. How can I use this?

Thanks
Norbert
