<div style="color:#000;background-color:#fff;font-family:tahoma, new york, times, serif;font-size:10pt;">Hi,<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>
