Although being totally correct, it threw me off as to why you had the "\[code\]" tag in front of it. But realizing after a minute that it's probably some sort of forum mishap that this is still shown.

I think that the Liferay space is overflowing with information, and although there have been improvements to the documentation from the side of the organisation, there's still a lot to be done, so I try to add snippets that I've used to relevant topics, because often, that's what I needed when searching for an answer.
(I know that this is a year old post) But thanks for posting the answer to your own question, this is very helpful to people searching the same thing and double frustrating if the op just writes "Never mind, found the answer" but doesn't post the answer ;).
