Track progress of running process by use of Observer pattern
Hi all,
I know this question has been asked before but this was a long time ago (2008) and the solution back then was to make use of some sort of logging mechanism which I don't completely understand.
I'm rather looking for a listener mechanism to track operator progress. I like to display a progress bar in my web application that approximately indicate total running time. I tried to add an observer to an Operator using the following
public void addObserver(Observer<A> observer, boolean onEDT)
method. Unfortunately, I don't get back any updates.
Any other ideas?

Hi Wouter,
you may want to have a look at the ProcessListener interface (ProcessRootOperator#addProcessListener) and the observable OperatorProgress (Operator#getProgress).
Cheers,
Marcel
