Where did you create the variable "index"? How are you exposing it to the JSP page?

In any case, if you're just using it as an index for the iterator tag, you don't need to; use the iterator tag's "status" attribute.

first thanks for your reply.

 <s:set name="index" value="0"></s:set>

     <s:checkbox name="authenticateForm.grantList[%{#index}].grant" value="authenticateForm.check(functionId,roleId)" />

I am using it for index of iteration but
i am iterating a iterator inside a iterator.
i need to track how many time that the check box get created

once again thanks for your reply

I'd still use the "status" attribute and save yourself some trouble. Why won't you do that?

In any case, please see ItDoesntWorkIsUseless. I have no idea what isn't working, so I have no way to assist you.
