Re: [rules-users] Using Character typed properties in Drool 5.3

Correction: Even using Character.valueOf('Y') does not work anymore in Drools 5.3. The validate works, but the compile steps fails because Drools is treating 'Y' as a String. However, in Drools 5.2 and prior, 'Y' was properly casted to a Character when the property it was being compared to was a property of type Character. If anyone has any insight on where the documentation address this change in behavior, I would appreciate some guidance. I am trying to re-standardize how our rules are coded for evaluating Character typed properties.

If I change my LHS to: BloombergColumn (columnName == "CRNCY", $cur : stringValue != null) Country (currency == $cur, emergingMkt == Character.valueOf('Y') || countryCode in ("BH","HR","CZ","EE","HK","HU","IL","KR","KW","MO","OM","QA","SA","SG","SK","SI","TT")) Then the validate passes. Was this change in behavior intentional? I don't see a reference to this change in the Drools 5.3 documentation, and this makes for a harder to read rule for our Drools analysts.
