Scene Builder could add missing '#' for method names.

Steps:
 - select any component that can have an action (i.e. button)
 - in Inspector window, under 'Code' -> type a method name [NOT starting with #] in any given text field (i.e. On Action)
 - in NetBeans, trying to generate the controller will not generate the required method because of missing '#'

This seems linked to issue DTL-5418 ?
