Error description

  • Assigning an Integer value to a BigDecimal variable may cause a
ClassCastException such as:
Error while executing ruleset: java.lang.ClassCastException:
java.lang.Integer incompatible with java.math.BigDecimal
com.ibm.rules.engine.util.EngineExecutionException: java.lang.
ClassCastException: java.lang.Integer incompatible with java.
math.BigDecimal
Caused by: java.lang.ClassCastException: java.lang.Integer
incompatible with java.math.BigDecimal

This may happen with a BAL rule such as:
then
    set myBigDecimal to my integer ;
Where "my integer" is a static method returning an Integer
value and myBigDecimal is a variable of type BigDecimal.

Problem summary


    

  • when converting simple type to BigDecimal and BigInteger a cast
cannot be used and an explicit operation is required. The
generated code does not handle properly this use case.

    



Problem conclusion


    

  • The code is fixed
