I have made a function in drl file. This function is calling another function from java file. This java file function returns an object, that I am not able to get. function SomeObject testFinction(SomeObject obj1) { String str; // Some calculations // ... str = "something after calculation"; // this function will return SomeObject based on str value SomeObject obj2 = Util.getSomeObject(str); // problem is here. obj2 is updated with same value of obj1. Expected value is diffrent from obj1. Checked getSomeObject(). It is working fine. // Some other calculations... // ... return anotherSomeObject; } rule "Check SomeObject" when //eval(tlvID == "57") someObj:SomeObject(id == "123") then testFinction(someObj); end I am using drool version 5.1.0. -- View this message in context: http://drools.46999.n3.nabble.com/Function-and-return-value-tp3317132p331...
