[jboss-jira] [JBoss JIRA] Closed: (JBRULES-1364) Drl parser 'or'

[Mark Proctor (JIRA)]

     [ https://jira.jboss.org/jira/browse/JBRULES-1364?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Mark Proctor closed JBRULES-1364.
---------------------------------

    Resolution: Done


I've executed the provided test project on trunk, which will be in the next 5.0.0.M5 release, and everything works fine. I've changed the test method in MiscTest to serialize the package, which should be enough to simulate the .pkg issue the user claims to be having. Everything seems to work, we won't fix this for 4.0.x. Please open with a failing test for trunk if you find any more issues on this.

> I'm not saying the second one shouldn't work(I fail to make the sense of it however), but it looks to me, the first one should.
