I've added the following code to the data grid library:

## Default is not to pass in value for pIndexes to draw in which case
      ## we use the base sequence for visible controls to determine indexes
to draw
      if pIndexesToDraw is not empty then
         put itemOffset(item 1 of pIndexesToDraw, sIndexSequencing) - 1 into
theSequence
      else
         put item sTableObjectsA["base sequence for visible controls"] to \
               (sTableObjectsA["base sequence for visible controls"] +
sTableObjectsA["row control count"] - 1) of sIndexSequencing into
pIndexesToDraw
         put sTableObjectsA["base sequence for visible controls"] - 1 into
theSequence
      end if

## AAG: Below I fix a possible bug
      repeat while char 1 of pIndexesToDraw is not a number
         delete char 1 of pIndexesToDraw
         if pIndexesToDraw is empty then
            exit repeat
         end if
      end repeat


With that in place, everything starts working.
