Hi on thing i noticed is that you have a notifyTopics attribute on you submit tag which i dont think is necessary and used wrong. i havent used dojo for a long time, so i am not sure if they changed any api or settings. but just a reminder you might need to take a look.
you dont have to specify href on your div.
you can change it or assign a href in your onclick function like
dojo.byId("resultDiv").href = "/example/result.action";
see if this help
