[rules-users] uninitialized planning value [error]

Is it possible setting planning entity with uninitialized planning value into solution? if it is possible, then how? :) plz, help me :) When I execute my code with not null planning variables everything work fine, but when i execute without setting planning variables I have [Exception in thread "main" java.lang.NullPointerException] ------------------------ 2012-02-14 17:32:08,119 [main] INFO Solver started: time spend (0), score (null), new best score (null), random seed (0).
