[rules-users] Problem calling a function returning String

Hi all, I am rather new to Drools and I have a problem using functions. I have a rule like: rule "rule 1" when eval(getEVAVersionsNr() == "1234") then System.out.println("rule fired"); end The getEVAVersionsNr() method is present in a Java class "ValidationUtilities.java", which I'm importing in my drl file and it looks like this: public class ValidationUtilities { public static String evaVersionsNr; public static String getZEVAVersionsNummer() { return evaVersionsNr; } } This static attribute "evaVersionsNr" is set to "1234" from another Java class before I fire my rules. So, I assume that the eval construct should return true. But, it does not return true and the consequence is not exected. Further info: When I modify my rule like: rule "rule 1" when eval(true) then System.out.println(getEVAVersionsNr()); end the consequence part is getting executed and 1234 is getting printed. I am really lost and I could not find out what goes wrong. If someone could find out what I am missing, I shall be thankful. Thanks in advance. -- View this message in context: http://www.nabble.com/Problem-calling-a-function-returning-String-tp24375... Sent from the drools - user mailing list archive at Nabble.com.
