Using the Rules module, is it possible to access the fields of a referenced entity of an entity? I've got this scheme:
entity person, bundle person, entity health, bundle health. Bundle health has field energy.

Bundle person has an entity reference of type health.

In Rules data selector, I want to access to person:health:energy. Is that possible?
Only, you have to add a Condition (in 'Elements') to the rule of the class "Entity has field", and then a whole bunch of the referenced fields of the entity will appear and will be available.
