[rules-users] Adding constraints to facts in DSL

[Andy Mei]

I am having the same problem as Stephane does.

It's pretty bad if I need to hard code the 'or' constraint within a single
DSL constraint.  I guess I could split a complex OR constraint to multiple
rules with the same consequences, it just an ugly hack.  Also, how does this
work if we need a Or constraint within another group constraint?

I just don't understand why the following doesn't work.

[condition][]There is a Cheese with=Cheese()
[condition][]- age is less than {low} =age < {low}
[condition][]Or=or
[condition][]- age is more than {high}=age > {high}
