Callback Javascript functions

[Stephan Michels <st...@apache.org>]

Hi,
exists there possibility to call flow function inside of a transformer?
I only found
 void Interpreter.callFunction(String, List, Environment)

First, the method returns no result. And second I must pass the 
environment, which is harmful for the current process.

I can skip the second problem by using a special masked enviroment,
which doesn't allow redirects etc.

But for the first problem I must change the signature of the method.

Is there any other way to do this? Thoughts?

Stephan.
