An illegal choice has been detected; dropdown list

I have a page view (www.example.com/page_view) with an exposed filter. The exposed filter is a dropdownlist.

In some occasions I would like to display directly the page_view with only the items with a value from the dropdown list. For that purpose, I pass the corresponding ID of that item to the URL

www.example.com/page_view?itemID=value

The page_view is correctly shown and the passed value is selected in the dropdownlist. So far, so good.

If I manually change the itemID value in the URL to a non-existing ID an error is shown on the screen:

An illegal choice has been detected. Please contact the site administrator and a red border is shown around the dropdownlist.

Is it possible to cache that error (maybe by validating if the itemID exists) so that only the search box is shown and a message like: "no matching results" ?

Thanks in advance.
