Hello, I have and less loop (the rule should only executed one for one InputObject) in the follwing rule although I use "no-loop": rule "rulename" dialect "java" no-loop when io: InputObject (type == InputObject.Type.Typename) then io.setStringPropertyValue(InputObject.PROPERTYVALUE, "somestring"); update(oo); end I've read that I have to overwrite hashcode and equals, can this be the reason? If yes, do you have an example how to overwrite these methods? Thomas
