Re: [rules-dev] Declared types - extension

There's also a quirk regarding the class resolution:- Given Person class:- package com.guvnor.domain; import java.math.BigDecimal; public class Person { private BigDecimal salary; public BigDecimal getSalary() { return salary; } public void setSalary(BigDecimal salary) { this.salary = salary; } } The following compiles OK:- package com.sample import com.guvnor.domain.Person declare Person end However the following does not (without explicitly importing java.math.BigDecimal - which is a field type in Person):- package com.sample import com.guvnor.domain.Person import com.guvnor.domain.Address declare Person end declare Person2 extends Person flange : String end Error being "Unknown DroolsError class org.drools.compiler.TypeDeclarationError: Unable to find class 'BigDecimal' ".
