Bug Report
What is the current behavior?
When the field to watch for is an object, the calculation does not fire, when the fieldname is provided as a string in an array.
It does work, when the name is provided as a string without the array or when it's provided as a regex in an array.
What is the expected behavior?
It should also fire when the fieldname is a string in an array.
