select box doesn't call set method in form bean when nothing is s elected

[gl...@agilent.com]

I have a multiple select box on my jsp (html:select).  When the user selects an item from the list, our form bean picks up that fact just fine.  However, if the user then un-selects that item (ctrl-click) so there is nothing selected in the box, the set method for that box doesn't get called so it 'remembers' that last value the user selected.
 
So, the question:  when a user de-selects everything from a multiple select box, how can struts know to clear the form bean variable since the html form is no longer sending data corresponding to that variable?
 
Thank you,
GlenR

I think you can clear the value of the property in the reset() method of your form bean.
