Of the code you posted, it looks ok to me.
However, id="#{index + 'working'}" is not legal. id must be a static value.

I am trying to use a datatable to render bunch of data and display an image
next to each row rendered based on the rowIndex. My code is below. The
problem I am seeing is that inside the graphicImage tag, the index doesn't
have scope. I can print the index before and after the graphicImage, but
when used inside the rendered attribute it always rendered to empty string.
I tried to use the index as part of the id for the graphicImage, something
like id="#{index + 'working'}" and it always rendered to just "working". I
have tried just using rowIndex, tried naming the rowIndexVar something other
than index, and no luck. I am wondering how I can use the current index
inside other tags. I have also tried using JSTL tags c:if to do the
rendering and it looks like the index doesn't have scope inside there
either.
The only other thing I can think may be wrong is that that the rendered
attribute of the graphicImage is only calculated once or is calculated and
applied to all the rows. The last c:if I have in my code below does work, so
it seems to only be something with the rowIndexVar inside a dataTable.
Last thing, ignore typos in variable names, as I changed the names of the
variables to hide the real function of this code (requirement). And
currentItemIndex is a c:set var defined earlier in the page.
