Looks like an 'or' bug. Which is surprising, as we had 'or' bugs in 4.x, and fixed a lot of them for 5.x.
Could you build and try 5.5.x here now, this is the branch for the 5.6 release: https://github.com/droolsjbpm/drools/tree/5.5.x If it's still not fixed, could you write an isolated test? Seems like you only need one rule, and two or three facts to trigger it. Ideally please re-use facts from the test classes already existing - details of how to write tests, and submit as pull requests is here: http://docs.jboss.org/drools/release/5.4.0.Final/droolsjbpm-introduction-docs/html/gettingstarted.html If you can get us this test pull request asap (next few days), we'll fix and get it into the 5.6 release. Otherwise you may have to wait some time for a fix. Mark On 18 Feb 2013, at 01:10, ismaximum <[email protected]> wrote: > Ah sorry..
