Re: [rules-users] qualified identifiers in constraints: not commutative?
At Mr. Legendre's suggestion, I removed the $o from my constraints, but
with the same result: (b.maxQ < q) works, but (q > b.maxQ) fails. I get
the error:
"Unable to create restriction '[QualifiedIndentifierRestr: < b.maxQ ]'
for field 'quantity' in the rule 'MaxQty'"

I notice an unexpected behavior when creating a technical DRL in

If I have a fact with a sub-fact, then binary operators don't seem to be
commutative.
Eg.,
declare Broker
maxQ: Integer
declare Order
q: Integer
b: Broker
The rule
$o:Order($o.b.maxQ < $o.q)
validates fine, but
$o:Order($o.q > $o.b.maxQ)
returns an error "Unable to create restriction
'[QualifiedIndentifierRestr: > $o.broker.maxQ ]' for field '$o.q' in
the
rule"
I'm new, so I want to make sure I'm not missing something obvious here...
