Thank you Edson.
Doe sthe new syntax support something like this:
$a : Person(
(age > 35 | < 25, zipCode == 23546 | == 68590, LastOrderPrice
300 | TotalOrderNumber > 2 ) | (some other logic)
)
then
$a.setStaus("KT")
If I can put all complex logic in the condition part, that would be great.
Our business logic is quite complex and the business partners do not
want to break them down because they have a lot of these rules.
Thanks,
Ye

Bill,
The way of doing that is using connective constraints as explained by
Steven previously:
$a : Person(age > 35 | < 25, zipCode == 23546 | == 68590)
This is a new feature that only works in 3.1M1 and later versions.
