[rules-users] Optaplan6.0.0Beta1:chaining-simpleScore OK, DRL Score corruption

[Paul T]

Hi Geoffrey

Thanks for attending to the Jira. 

I am at a loss as how to continue using Rete if my model cannot be handled
by Rete so as Phreak works .....

tried out using Drools,OptaPlanner as per 2013-05-14 snapshots,
turned on Phreak in OptaPlanner ScoreDirectorFactoryConfig,
used  OptaCrashExample-2.tar.gz from the Jira ,
changed testConfigDRL.xml from minimalAcceptedSelection to
acceptedCountLimit 

which resulted in the following error:        which appears similar to the
previous score corruption problem.

Any suggestions:
- do you think that my requirement is unsuited to using rule based scoring ?
- stay with SimpleScore ?

Thanks
Paul
