Hi Dave Newton,
Thanks for your reply quickly!
please see my problem:
generated HTML source segment by S2
...
<input type="checkbox" name="roleIds" value="ROLE_ADMIN" id="listRole_roleIds"/>
<input type="hidden" name="__checkbox_roleIds" value="ROLE_ADMIN"/>
<input type="checkbox" name="roleIds" value="ROLE_SUPER_USER"
id="listRole_roleIds"/>
<input type="hidden" name="__checkbox_roleIds" value="ROLE_SUPER_USER"/>
...
case1: if i checked all above checkboxs, the string array "
{"ROLE_ADMIN","ROLE_SUPER_USER"} " will be getted at server-side.
case2: if i only checked first checkbox, then at server-side the string
array "{"ROLE_ADMIN"}" will be getted.
case3: if i didn't select any checkbox, then at server-side the string array
" { "false" } " will be getted.
but in my opinion, the getted value should be NULL in case3. what's your
opinion?

Why?
S2 automagically deals with one of the headaches of HTTP (not returning
unchecked box values) by adding a hidden field to the form. This makes
the server side code much cleaner, IMO.
