[jboss-jira] [JBoss JIRA] Commented: (JBRULES-736) Should be able to compare different numeric types
[ http://jira.jboss.com/jira/browse/JBRULES-736?page=comments#action_12356023 ]
Mark Proctor commented on JBRULES-736:
--------------------------------------
currently that's because you have an int and an Integer, which we don't have
evalutors to handle that. We'll look into try to make this work for M3.
Should be able to compare different numeric types
