From 5b2ddc15bd2c30d9f9033a0c4cf50e32827ef0c6 Mon Sep 17 00:00:00 2001
From: Artur Signell <artur@vaadin.com>
Date: Wed, 13 Nov 2013 14:56:06 +0200
Subject: [PATCH] Make test work reliably by activating @Push

Additional test now ensures that access() works both when called
before init() is done and after init() is done
