passing in a param on method OR 2 iters in foreach

["G.L. Grobe" <ga...@grobe.net>]

While trying to figure out a way to loop through two Vectors in a single #foreach statement ... I found something that might help if I can figure the following ... Is it possible to return an element from a Vector by passing in the index as shown below?

   #set ( $idx = 0 )
   #foreach ($span in $row.rowSpan)

      #if ($span == 0)
         <!-- do nothing -->
      #else
         <td style="width:50px" bgcolor="$row.rowState($idx)" rowspan="$span">$idx</td>
      #end

      #set ( $idx = $idx + 1 )
   #end

Any help much appreciated.

If $foo is truly a java.util.Vector, then $foo.elementAt($idx) will return
what I think you are asking for...
