Re: [rules-users] semantically equivalent DROOLS L-value expressions?
Ben:
Consulting the "Expert" manual may shed some light on your puzzlement.

The behavior of the Conditional Element or is different from the
connective || for constraints and restrictions in field constraints.
The engine actually has no understanding of the Conditional Element
or. Instead, via a number of different logic transformations, a rule
with or is rewritten as a number of subrules. This process ultimately
results in a rule that has a single or as the root node and one
subrule for each of its CEs. Each subrule can activate and fire like
any normal rule; there is no special behavior or interaction between
these subrules. - This can be most confusing to new rule authors.

Ha! That there last sentence ;-)

Thanks.
I'm sure that it is my lack of DROOLs maturity that leaves me kind of
bewildered at the need to re-factor R2 as R2a and R2b. Frankly, I'm even
a little confused as to why R1 is not syntactically correct (it would be
my
"newbie-preferred" way of expressing my understanding of what I want the
rule to "say").
Will play with and exercise your R2 re-factor recommendation, I'm willing
to
put in the DROOLs work until I "get it".
Thanks again.
