I can't say for certain, but it sounds to me like, sometimes, your creationComplete handler is firing before the RemoteObject returns data, thus firing the result handler. Unless you have control over the Internet, I don't think there is any way to guarantee that your asynchronous code (AKA The result handler) will be finished before your synchronous code (creationCompete) is executed.
You should handle your JavaScript stuff int he result handler of your RemoteObject, not in creationComplete.
