     [ https://issues.jboss.org/browse/DROOLS-1397?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Patrick Mingard updated DROOLS-1397:
------------------------------------
    Workaround Description: 
As proposed on the stackoverflow topic, this works :

{code:java}
rule comms
when
  $conv: Convention()
  $comm: Comm() from (ArrayList)($conv.getComms()).get(Type.AAA)
then [...]
{code}

Please note the difference is an ArrayList cast (with a few parentheses).

>         Environment: JDK 1.7, JUnit test, exact drools version is 6.5.0.Final-redhat-2

> I'm migrating an application that used drools 5.3 on the newer drools 6.5 version. 
> I'm using a decision table, And one of my condition is accessing a Map which has an enum class as a key. It is not compiling unless I do a strange ArrayList cast.
