Description
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)
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
$bus.weight is a BigDecimal type property.
(*2)
