That's a good point, still not the true cause -- checking them will be a good practice, but will not solve the problem here, because the exact same code works in https://github.com/suntong/lang/blob/master/lang/Go/src/ds/PersistentData-GOB.go. I've verify from the code and result that the save *is* actually working. -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
