          Components: Drl Parser/Builder
    Affects Versions: 4.0.6
         Environment: all

            Priority: Minor
             Fix For: FUTURE


Not sure if this is MVEL or drools itself, but it would be nice if it would do null checks on fields for you rather than having the rule author do it.  Example, when doing something like:

when
   Object(value1.value2 == something)
  
  
before attempting to read value2 it makes sure value1 is not null, and if value1 is null than rather than throwing an error like it does currently, just consider the rule as not matching.
