From 52eccc6cfa0f3b3649d60e3173382cdb68828f44 Mon Sep 17 00:00:00 2001 From: Aleix Pol Date: Thu, 10 Jul 2014 02:39:37 +0200 Subject: [PATCH] Introduce a new warning in moc, to notify about duplicated properties At the moment, it's possible to have 2 properties with the same name, which doesn't make much sense. Notify the user about that so she can react on it.
