Steps to reproduce:

1. From Content -> Dynamic Data Lists, create a new Data Definition, add a test box field.
2. For the new Data Definition, create a Display Template. Under Script field, use Text Box under Data List Record Fields.
3. Add a new Dynamic Data List based on the new Data Definition
4. On the Liferay home page, add a Dynamic Data Lists Display portlet
5. Select the list created in step 3 to display
6. Exit to the page, then go to the portlet's configuration
7. Under "Optional Configuration," change the Display Template to the Display Template created in step 2
8. Save the configuration and exit back to the page (or refresh)

Expected result: the Display Template is loaded and rendered as expected
Actual result: the Display Template fails to load, and an error is thrown in the console
