[kepler-users] [kepler-dev] stopping workflow,

[Tristan King]

You may need to modify your first actor to have another output port,
which outputs "true" if the End of File has been reached, and "false" if
it has not. this can then be put through a Boolean Switch, which can
then send a token to the "Stop" actor.

I've attached a workflow that performs a similar task to what you're
trying to do.

Your only other option is to make sure actor1 reads in the entire file
before sending the data to actor2.

Hope this helps
