[rules-users] Possible bug

[Edson Tirelli]

    Pavel,

    This is a bug. It was fixed last week:

https://jira.jboss.org/browse/JBRULES-2556

    When you say you are using the "official" 5.0 version, do you mean the
Red Hat supported version or the community version? If you are a Red Hat
subscriber, you can ask them to provide you with a patch.
