Unlimited option gives fatal error when saving node #9

I placed some of the rng fields on the node form. When selecting the unlimited option on the node form (not on the event settings form), a fatal error is generated. On the event settings form everything works fine. Here's the error output:

I was running into this as well and did some investigation and found the following: 1) The "min" field setting on number fields gets set to "1" by default. Since the "Unlimited" option on the field widget sets a value of "0". This results in a validation error when the form is submitted if the "unlimited" radio button is selected. 2) The $error_element variable in the WidgetBase.php method is getting set to null, which is causing the request to fail with a hard error instead of simply showing a validation error. I'm guessing the render array for the field widget is probably malformed in some way, but this will require deeper investigation.

For now though, I am successfully able to avoid the error by simply setting the 'min' setting on the Maximum Registrations field to 0.
