I want to work on "Being able to add a listener when creating a new JPA entity "(https://issues.jboss.org/browse/FORGE-2094). Basically, when I create a new JPA entity, I want to be able to add as many listeners as I want.
How do I do to be able to have several choices on an attribute ? I only know how to manage one value but not several one. Is it doable ? Any exemple in any Forge command ?
Thanks
