Hi,
When a workflow operation fails, we would like to be able to pause
the workflow, and wait for user intervention to decide what to do next.
The default error handling we are using just zips the media package and
copies it to failed.zips. When the problem is solved, the workflow has
to be re-executed from the beginning. Even retrying the failed operation
a few times doesn't help a lot, because it may take some time to solve
the error and/or 'sanitize' the service.
The behavior we are thinking is: if there's an error, pause the
workflow, and make a screen available where the user can decide what to
do next: re-execute current operation, skip current operation and
continue, stop workflow, (something else?). This should be flexible
enough to be configurable by operation. Is there anyone doing something
similar? Any ideas on how to implement this using the current workflow
mechanism?
Thanks,
Rute
