I would like to do that, but if I have a Device object on the top of the
value stack (or perhaps somewhere near the top), how would I grab that
and pass it to the function? I just tried this and it didn't work:

<tr class="<s:property value="%{getStatus([0])}" />">

(after modifying the function to take a Device instead of an ID number).
