The example in the tutorial for the influence diagram with 2 decisions don't work

[Former user]

When clicking inference button, an error is shown:

error during inference: null

[Miguel Ángel Artaso Landa]

The error was only reproducible in org.openmarkov.full-0.1.4.jar The present code in the repositories does not launch this error. Thus, in the next deployment of the code the problem will not show up.
