Predefined doesn't render value in element index

I get the following when editing an element, which is correct:

But when trying to show that value on the element's index, I get nothing:

Ah - I now see that I need to re-save all elements again for this value to be set, so its a slightly different issue, but related to #89

While handy in some cases this field can sometimes feel like a bit of a hack as well. I'd caution to use it sparingly as the more specific scenarios that it tries to solve the more it may just make sense to create a custom field type for the specific need.

For what its worth, we ended up switching back to Preparse. We also noticed that at times the field was outputting the actual twig code, I suppose when a parsing error or something occurred?

I think this sort of field type is a pretty valid use-case, as opposed to a custom field every time you want a calculated value in a field. Having said this, first time I've used this field.
