Attribute Value providers in JavaScript

Hi,
Has anyone tried example from this jazz wiki:
https://jazz.net/wiki/bin/view/Main/AttributeValueProviders#Write_Providers_in_JavaScript
about getting Exposure provider for chosen attributes:
risk probability and
risk impacts.
I created Project Area with this process template, and my question is what I must configure to get it working.
Regards,

I figured where is the problem:
# Allow to use scripts deployed as process attachments
com.ibm.team.workitem.process.scripts.enabled=true
I didn't add this note to teamserver.properties
