[jboss-jira] [JBoss JIRA] Closed: (JBRULES-1654) eval() Incorrectly Evaluating BigDecimal to False

eval() Incorrectly Evaluating BigDecimal to False ------------------------------------------------- Key: JBRULES-1654 URL: https://jira.jboss.org/jira/browse/JBRULES-1654 Project: JBoss Drools Issue Type: Bug Security Level: Public(Everyone can see) Affects Versions: 4.0.7 Reporter: Andrew Frederico Assignee: Edson Tirelli Fix For: 5.0.0.FINAL 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);
