Несколько обновлений в правилах - исключение

0 голосов
/ 26 марта 2019

Мы использовали drools 7.7 для написания правил. Мы пытаемся написать несколько правил, в каждом правиле мы обновили факты в действии и пытаемся использовать обновленные факты в следующем условии правила, но слюни выбрасывают ниже исключения.

Мы запускаем слюни в ПОСЛЕДОВАТЕЛЬНОМ РЕЖИМЕ. со следующими конфигурациями: - 

 kieSessionBuilder.setKieBaseMap(
        ruleGroupId, kieHelper.build(SequentialAgendaOption.DYNAMIC, SequentialOption.YES));

Rule 1
Salience "1"
no-loop
when
$allocatedQuantity : AllocatedQuantity(receivedQuantity<allocatedQuantity)
$inventory : Inventory (location == 'A')
then
$allocatedQuantity.setReceivedQuantity($allocatedQuantity.getReceivedQuantity()+ $inventory.getQuantity());
update($allocatedQuantity);
end

Rule 2
Salience "2"
no-loop
when
$allocatedQuantity : AllocatedQuantity(receivedQuantity<allocatedQuantity)
$inventory : Inventory (location == 'B')
then
$allocatedQuantity.setReceivedQuantity($allocatedQuantity.getReceivedQuantity()+ $inventory.getQuantity());
update($allocatedQuantity);
end


Rule 3
Salience "3"
no-loop
when
$allocatedQuantity : AllocatedQuantity(receivedQuantity<allocatedQuantity)
$inventory : Inventory (location == 'C')
then
$allocatedQuantity.setReceivedQuantity($allocatedQuantity.getReceivedQuantity()+ $inventory.getQuantity());
update($allocatedQuantity);
end

Rule 4
Salience "4"
no-loop
when
$allocatedQuantity : AllocatedQuantity(receivedQuantity<allocatedQuantity)
$inventory : Inventory (location == 'D')
then
$allocatedQuantity.setReceivedQuantity($allocatedQuantity.getReceivedQuantity()+ $inventory.getQuantity());
update($allocatedQuantity);
end


Rule 5
Salience "5"
no-loop
when
$allocatedQuantity : AllocatedQuantity(receivedQuantity<allocatedQuantity)
$inventory : Inventory (location == 'E')
then
$allocatedQuantity.setReceivedQuantity($allocatedQuantity.getReceivedQuantity()+ $inventory.getQuantity());
update($allocatedQuantity);
end

до 4-го правила оно выполняется, но в 5-м правиле оно выдает ниже исключения: - 

java.lang.NullPointerException: null
