And there was a construction heuristic that should have already
filled in that planning entity?<br>
Enable DEBUG logging, so you can see in the construction heuristic
log if it does steps which change that variable from null to a
non-null value.<br>
<br>
If you have 2 <constructionHeuristics> configurations before
the <localSearch> configuration (which I don't see how you
could with the 5.5 CH behavior):<br>
I just fixed a bug/feature for 6.0 earlier this week to support
that.<br>

<br>
I'm trying to implement a basic local
search (really new to it).<br>
<br>
When I run my project I now get:<br>
<br>
Exception in thread "main"
java.lang.IllegalStateException: Phase
localSearch started with an uninitialized
Solution. First initialize the Solution.
For example, run a phase
constructionHeuristic first.<br>
at
org.drools.planner.core.localsearch.DefaultLocalSearchSolverPhase.phaseStarted(DefaultLocalSearchSolverPhase.java:120)<br>
</div>
</blockquote>
You have a construction heuristic configured,
so all @PlanningVariable's should be different
from null after that phase is ended.<br>
So when the local search phase starts, that
check should be ok and not throw that
exception.<br>
<br>
Comment out local search, write the solution
to disk an verify that all planning variables
are now not null.<br>
Or debug where that exception is throw and
inspect
phaseScope.getSolverScope().getScoreDirector().getWorkingSolution().<br>
