Hi Olivier, thanks for detailed answer and the updates.
Currently, I handle this missing feature in my program with a "deamon" async thread, which is started on place 0 in the relevant finish. The daemon only terminates, if all (or no) handler were triggered. In worst case, no handler is triggered in time, the deamon terminates, and the handler will not work as expected. I think this case is very unlikley. However, a handler inside a finish would be very nice. cheers, Jonas Am 10.10.2016 um 22:44 schrieb Olivier Tardieu: > Hi Jonas, > > The place failure handling scheme is a work in progress. > > In principle I would like place failure handlers to be a kind of > optional task (that runs iff a failure is detected) > inside the enclosing finish.
