[jboss-jira] [Red Hat JIRA] (DROOLS-5899) Expression like BigDecimal_type_property = BigDecimal_type_property.divide(BigDecimal_value) causes a build failure in executable model.

Expression like BigDecimal_type_property = BigDecimal_type_property.divide(BigDecimal_value) causes a build failure in executable model. ---------------------------------------------------------------------------------------------------------------------------------------- Key: DROOLS-5899 URL: https://issues.redhat.com/browse/DROOLS-5899 Project: Drools Issue Type: Bug Components: executable model Reporter: Luca Molteni Assignee: Luca Molteni Priority: Major Labels: support Compiling a rule like (*1) which is described in MVEL dialect and uses an expression like _BigDecimal_type_property_ = _BigDecimal_type_property_.divide(_BigDecimal_value_), for example (*1-1), with executable rule models enabled, an error like (*2) occurs. This issue occurs in the case of using the other basic operation add, subtract and multiply as well as divide. (*1) {noformat} package com.example.reproducer import com.example.reproducer.Bus import java.math.BigDecimal dialect "mvel" rule "bus3d" when $bus : Bus() then $bus.weight = $bus.weight.divide(BigDecimal.valueOf(1000)); ..... (*1-1) System.out.println("***** " + $bus + ", weight = " + $bus.weight); end {noformat} $bus.weight is a BigDecimal type property. (*2) {noformat} [ERROR] Unable to build KieBaseModel:rules CompilationProblemErrorResult: org.drools.mvelcompiler.MvelCompilerException: RHS doesn't have a type {noformat}
