Description
Compiling a rule like (*1) which is described in MVEL dialect and uses a compound assignment operation like BigDecimal_type_property += BigDecimal_value, for example,
- $bus.weight += $bus.weight; ..... (6c) or
- BigDecimal bd1 = 1000; $bus.weight += bd1; ..... (6d)
with executable rule models enabled, an error like (*2) occurs. $bus.weight is a BigDecimal type property.
The same issue also occurs in the case of using '-='.
For '*=' and '/=', no compilation error occurs but the value of $bus.weight does not change by the operation.
(*1)
package com.example.reproducer
import com.example.reproducer.Bus
dialect "mvel"
rule "bus6c"
when
$bus : Bus()
then
$bus.weight += $bus.weight; ..... (6c)
System.out.println("***** " + $bus + ", weight = " + $bus.weight);
update($bus);
end
(*2)
