Hi Samuel,
None of my implementations have a null instance asserted into the
working memory. Which code is doing insertLogical(null)?
IMHO, It shouldn't do that.
In your code I noticed last time that you used smart functions.
The problem is, those smart functions don't use DRL, so don't do forward
chaining, re-iterated over a lot of stuff while calculating the result,
so they break delta score calculation.
Those smart functions also did a lot of things that looked like black
magic to me, which could be causing your wierd behaviour.
Maybe you can rewrite those functions as DRL patterns?

Hi all, Hi Geoffrey,
I have implemented a first version of the solution with two types of move :
status move and another tour move.
When i try to retrieved the scoreDetailList, the iterateObject is not clean.
It contains many null values. I don't know if it's normal but it has for
consequence that the method SolutionBusiness.getScoreDetailList() return a
null list.
Iterator<ConstraintOccurrence> it = (Iterator<ConstraintOccurrence>)
workingMemory.iterateObjects(new
ClassObjectFilter(ConstraintOccurrence.class));
while (it.hasNext()) { //Doesn't in the loop because a value is null
..
}
Maybe you have an idea.
