问题 I would like to ask a question about wether or not I should do the migration to Liferay 6.2. Me and my team are working since 4 month on a portal quite big developed with Liferay 6.1 (CE edition) and now, since the project publication date is still 4-5 month ahead (so I do have time), I was wondering if doing the migration to 6.2 now is a good choice.

I have a vague idea of how it might be done so I searched around figuring it would be posted somewhere, but I can't find anything on it. Incidentally, I want to put whatever code I come up with inside the view.jsp of the portlet. I would use velocity markup here but I

问题 I am making a change to a native Liferay portlet, that comes with Liferay Intallation. How can I change a function to my own implementation by a hook or similar approach?
