    Component/s:     (was: Decision tables)

> eval() Incorrectly Evaluating BigDecimal to False
> -------------------------------------------------
>
>                 Key: JBRULES-1654
>                 URL: http://jira.jboss.com/jira/browse/JBRULES-1654
>             Project: JBoss Drools
>          Issue Type: Bug
>      Security Level: Public(Everyone can see) 
>    Affects Versions: 4.0.7
>            Reporter: Andrew Frederico
>         Assigned To: Mark Proctor

> Even when the condition of an eval() in the "where" block results in TRUE when used in normal code the rule does not fire directly because of the eval() statement.
> My class definition:
> class BuyOffer() {
>    private BigDecimal amount;
>    ...
> }
> The getter from the class:
> public BigDecimal getAmount() {
>    return amount;
> }
> Assuming that I've setAmount() to something non-zero earlier in the code, the line of code that evaluates to TRUE (verified by System.outing the result):
> buyOffer.getAmount().compareTo(BigDecimal.ZERO) > 0
> My eval() statement:
> eval( buyOffer.getAmount().compareTo(BigDecimal.ZERO) > 0 )
> With eval() in place the rule does NOT fire.  When removed it DOES and the following line of code prints TRUE.
> System.out.printf("buyOffer.getAmount().compareTo(BigDecimal.ZERO) > 0: %s\n", buyOffer.getAmount().compareTo(BigDecimal.ZERO) > 0);
