Hi Folks,

I am new to OptaPlanner, so please forgive me if this is a stupid question.

I developed a project to solve a worker assignment problem based on OptaPlanner. I have a java class "Demand" which has the information of capacity needed for each shift.

I added it to the solution class as a problem fact, since it should never be changed. Then I wrote rules saying that when the supply on that shift can not satisfy the demand there will be a point loss.

The problem I met is that when stepping into local search phase, the solver can not access to this class.

For instance, I have the following rule:

rule " test rule"

when

$s : Shift($i : index)

$d : Demand(shift.getIndex() == $i)

then

System.out.println("Test rule fired.");

end

From console log I observed that at local search phase this rule was never fired.

Does anyone have any thoughts on why this happened and how I should solve this problem? I will appreciate your help.

Thanks,
