Hi Prasanth, Yes, I think. Now I can recall a long discussion about this at [1]. i.e. you also can keep array list of long but override the interceptor like below [2]:
<action name="ListConverterTest" class="com.afs.ListConverterTestAction"> <interceptor-ref name="defaultStack"> <param name="checkbox.uncheckedValue">-1</param> </interceptor-ref> Kind Regards.
