Yes, the controller extends SimpleFormController. I was using the onBind
method because i saw it on another source code file. In fact i'm not using
onSubmit on this controller, so it is empty...

I already tried the PropertyEditor for Week and User, and everything
compiles fine but i get a null pointer exception because User and Week can't
be resolved (i retrieved them from the database with request parameters
because they are preloaded data, and the application won't
insert/update/delete them).

As for the rest of the controller, it is empty, i just used the onBind
method. I did not understand very well the "changes propagating to the code
run in the cointainer" part. I call clean before every try, and i use
command line so i take this should be no problem?

As can be seen, i initialize the Activity object in the WeekActivity object
like this

  Activity activity = new Activity();

Because, logically, a new activity should be inserted in the DB each time
for every WeekActivity object. The form controller is for the WeekActivity
object, and Activity should be saved before the WeekActivity. In the jsp i
just do this:

<form:hidden path="activity"/>

So this should refer to the activity property in the WeekActivity, but the
activity has not been saved yet so hibernate complains about activity_id not
having a default value. Should the path be "activity.id" or maybe an allowed
field should be "activity.id" in the controller mapping?

I include both hbm.xml files for Activity and WeekActivity. Something tells
me the problem is somewhere around the jsp or the controller...because
everything else looks ok! Thanks a lot for paying attention to me   Mike ;)
