Hi Yasser, Even after having the param the ArrayList<Long> was not populated with -1 for unchecked checkboxes. The ArrayList<Long> is in form. The set method in the form is not getting called when I don't check any of the checkboxes. I am using a checkboxlist rather than individual checkboxes.
<interceptor-ref name="scope"> <param name="key"></param> <param name="session">form</param> </interceptor-ref> <interceptor-ref name="defaultStack"> <param name="checkbox.uncheckedValue">-1</param> </interceptor-ref> Thanks, Prasanth On 2/5/19 5:43 AM, Yasser Zamani wrote: > Hi Prasanth, > > Yes, I think.
