[rules-users] Null pointer while integer comparison

[Holla Sachin-a23031]

i was just wondering if this behavior is consistent... say i have two
rules like these:
 
rule "Equals"
when
    MyFact ( integerAttribute == 10 )
then 
    .....
end
 
rule "Greater Than"
when
    MyFact ( integerAttribute > 10 )
then
   .....
end
 
 
now, if MyFact returns null for integerAttribute the second rule results
in NullPointerException while asserting the fact.. but the first rule
does not. i am not able to reason out if this is expected
functionality... :(
please help..
 
thanks in advance
