The following program produces an error: " class Employee { String name int empId String toString() { return name + ": " + empId } } e = new Employee() println e " The error is "Cannot invoke method: plus on null object". What I expect to see is "null: 0". I can see why this is happening but I don't know the best way to fix it. Another issue is that when anything goes wrong in groovy, I get a big stacktrace, java style. As a user of the system, I'd rather just see a concise one line error. Thanks, keep up the good work. I'm certainly going to keep my eye on this language. JJ Furman
