The problem is that the Validate() functions take pointer receivers but you MyStruct uses the actual FooTypeA and FooTypeB values. You can get it to work by either making the Validate functions take a copy of the value: https://play.golang.org/p/qtpZDC6tezg or by making the members of MyStruct pointers: https://play.golang.org/p/cYghM8IipQ3 Check out the Method Sets section of the Go spec: https://golang.org/ref/spec#Method_sets -ayan -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
