I migrated our application to RF 3.1.3 CR2 for testing a couple of hours ago. Until now there's nothing to complain of.
( http://jira.jboss.org/jira/browse/RF-1487 is still there, but I know I have to wait until 3.2.0)
So I can hope we get straight to 3.1.3 G.A. Again thank you and the whole team for your great work.
