This question already has an answer here:
I wanted to ask a question about Hibernate and polymorphism, and before asking it I searched on Google, and lo and behold, there was already a question on SO about it. It's three weeks old and has never really been answered. What's the most appropriate way to "bump" it up to being higher up in the "active" list? I don't have an answer to it myself, and I'm not the OP so I don't want to edit the original post. And SO etiquette says I shouldn't ask a duplicate question. What should I do?
