> <input type="text" name="<%= name %>">

>
>This show magically the correct values on screen but as this in HTML code :

><input type="text" name="surname[0]" value="toto">

><input type="text" name="surname[1]" value="tata">

>So when i submit this form
>The usersForm can't retrieve new values because of the bad name of property
>(surname[0], name[0], surname[1], name[1],...)
I also tried this :

I get this exception : java.lang.NullPointerException: No indexed value for
