[rules-users] uninitialized planning value [error]

[Nurlan]

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]
