Hi davook,

Please consider our Basic StockList example; you could duplicate a field maybe because you want to format it in two different ways.

In the static grid definition the code will be something like this:
HTML Code:
       <td><div data-source="lightstreamer" data-field="ask" data-replica="ask-A">-</div></td>
       <td><div data-source="lightstreamer" data-field="ask" data-replica="ask-B">-</div></td>
In this way in the onVisualUpdate callback you can directly access the cells separately
Code:
       var newValue = info.getChangedFieldValue(field);
       if (newValue != null) {   
       info.setCellValue("ask", myValueFormattedFlavourA(newValue), "ask-A");
       info.setCellValue("ask", myValueFormattedFlavourB(newValue), "ask-B");
       }
Regards,
Giuseppe
