[rules-users] Planner - Initialized solution & local search

[Garf]

I'm using v5.4. I've built a prototype which uses the constructionHeuristic,
and localSearch, as the example does, and am able to run the solver (though
it still doesn't do a good job of solving at this point).

I've now added customSolverPhase, and set it to use an initializer class
which implements CustomSolverPhaseCommand.

In my changeWorkingSolution, I call scoreDirector.beforeEntityAdded(), and
then set the planning entity's planning variable, and then call
afterEntityAdded().

If I leave any entities unadded -- and let the constructionHeuristic
(BEST_FIT, etc) do the fitting (which I can verify from the logs)-- I then
get this exception:

/java.lang.IllegalStateException: Phase localSearch started with an
uninitialized Solution. First initialize the Solution. For example, run a
phase constructionHeuristic first./

For now, I can update my code to ensure that all of the entities are fitted
and bypass the constructionHeuristic, but I'm curious why this error is
getting thrown. I did hunt through the source code to look at all the
isInitialized() methods, but I haven't yet stepped through to see which one
returns false any why.

As for turning on TRACE mode, see my
