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.
