You can get the original list by doing the following
from your decorator class:
Object fullList =
this.getPageContext().findAttribute("fullList");
where "fullList" is the name of the list configured
in the name attribute of the displaytag table tag,
e.g.,
<display:table id="row" name="${fullList}"...
With the the full list in hand, you can do your grand
total.
That's half the answer. You also need a way to
determine whether it's the last page being displayed.
Otherwise, this grand total row will show in every
page. Gotta think about that one.
