Description
String relational comparison fails with executable-model
Person( name > "Bob" )
generates Predicate like this:
@org.drools.compiler.kie.builder.MaterializedLambda() public enum LambdaPredicate23581163B2FDAA9B650DDB3B8C587DE2 implements org.drools.model.functions.Predicate1<org.drools.modelcompiler.domain.Person> { ... @Override() public boolean test(org.drools.modelcompiler.domain.Person _this) throws java.lang.Exception { return org.drools.modelcompiler.util.EvaluationUtil.greaterThanStringsAsNumbers(_this.getName(), "Bob"); } }
then, fails with this error:

FYI) It should be supported
https://docs.jboss.org/drools/release/latest/drools-docs/html_single/index.html#drl-operators-ref_drl-rules
4.1.8.6. Supported operators in DRL pattern constraints <, <=, >, >= Use these operators on properties with natural ordering. For example, for Date fields, the < operator means before, and for String fields, the operator means alphabetically before. These properties apply only to comparable properties. Example constraints with before operator Person( birthDate < $otherBirthDate ) Person( firstName < $otherFirstName )
