As it says in the following message:
http://www.mail-archive.com/struts-user@jakarta.apache.org/msg06473.html
"The the normal behavior of an checkbox is, that it will submit the value of
the checkbox with the form if the user has selected the checkbox. If it is
not selected, the browser will not send the value of the checkbox to the
server."
So HTML is not sending back any value pairs when the checkbox is
"unchecked". Thats why you are not getting anything on your console from
your method:
> public void setIsPublic(boolean is){
> System.out.println(is);
> this.isPublic=is;
> }
If HTML does not send back request parameter pairs for unchecked checkboxes
then Struts can't do anything. It must be still set to true because your
form is in session scope - the message below says something about reset() -
I haven't had to deal with this, all my ActionForms are in request scope
