Two possible issues here:

1. activity.activity is invalid (unless your getters do not correspond to your member variables) because Course.activity is a list. You need to address a particular list element - e.g. activity[0].activity. You'll also have to make sure it actually exists.

2. Have you configured your FormController correctly? Does it pass Course instance to view as it should? Take a look at Spring MVC tutorial for an example.

If after you've fixed #1 and verified that #2 is done correctly the error doesn't go away, please post more details (FormController mapping / source).
