[rules-users] [planner] uninitialized planning value [error]

[Geoffrey De Smet]

For the record:

In your solverConfig, you're missing a |<constructionHeuristic>| section 
(use FIRST_FIT) before the |<localSearch>| section, see manual for more 
information or most of the examples.

I 'll file a JIRA to get a better exception message when this occurs.
