On the demo site - http://wpmaster.demo.civicrm.org/wp-admin/ I have created a new set of custom fields for Events - "Events custom fields" with one text field - "test1".
I have added value "tst" for this custom field in the event template "Free Meeting with Online Registration".
When using this template on a new event the custom field value is not populated with what's in the template. Do I have to use hook to copy over custom data? If so what's the hook?
