"Handling Errors"
Contributor I
Hi,
I ask for advice on handling errors in Rapidminer.
In the code below you can find a process that is deliberately in error controlled , I used to do this "Handle Exception" and "Branch".
it is correct or is there a better way?
There is also the possibility of having an error code instead of just the description? if yes how?
Sorry for my English but Google is my friend
