I am not sure how common that is
Just an idea for you:
If you have a uniq id for each item, than you can do:
<form>
loop to print item info
{
<input name="id" type="hidden" value="<%=itemId%>">
<input name="prop1" type=text value="<%=itemProp1%>">
<input name="prop2" type=text value="<%=itemProp1%>">
}
</form>
than on server you can use
String[] ids = request.getParameterValues("id");
String[] props1 = request.getParameterValues("prop1");
String[] props1 = request.getParameterValues("prop2");
than loop through ids, and for item with id[i] set prop1 to props1[i] and prop2 to props2[i].
Client side gets a little bit more complicated if you need to use checkboxes, but not much.
