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)
          Components: Decision tables
    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);
