I have fixed it. It won't show the assignment anymore. But the fix works
only in IE and Firefox, opera users will be able to edit the assignment,
but they will get error on save (but not the ugly exception - nice error
page is work to be done :))
Hmm.. not much to do about opera if I can't force it to reload page on
back button.

Btw. What do you think would be correct action?
Showing user a message, that assignment has been deleted,
or
Being able to save the assignment, without throwing any exception?
(or showing user a message, that assignment has been deleted and
afterwares go to the assingment and allow to save it)

Cool, very nice app!
You said that any button could be pressed, so I did ;-))
* My Assignments, select any assignment and click "show"
* Click "Delete"
* Hit Back, the data is still there
* While still on "show" page hit Refresh. Hmm, seems like the data was
not deleted.
* Click "Save" and get an exception:

This is exactly why I think that default Wicket approach with page
versioning and restoring model when Back button is pressed is faulted.
It brings too many issues. I think that the page should be
synchronized with model not the other way around. But... well, as long
as I do have an option of doing things in Wicket my way (and I do have
this option), I am not going to critique much ;)
