For 6.0, implementing cloneSolution() yourself will be optional, as
we 'll have a reflection based implementation out-of-the-box too.<br>

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:

uninitialized
Solution. First
initialize the

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>
