Hi,

Suppose I have a class Foo with integers a, b and c ( methods getA getB and getC respectively ) and I Want to check if an object of Foo satisfies

a - (b + c) > 0

Is this the best way I go about doing this ?

rule "Foo check"
    when
        Foo( varA : a , varB:b, varC:c )
        eval( varA - (varB + varC) > 0 )
    then
          <do actions>
end

Writing this as

rule "Foo check"
    when
        Foo( a - (b + c) > 0 )
    then
          <do actions>
end

doesnt seem to work. Its not able to find the variables (a, b and c ) from the getA getB and get C methods.

Thanks

Jai
