Sightly Code to iterate over Map which is list of String - Does not work in 6.3

Hi All,

We have sightly code which was working fine in 6.1 and stopped working in 6.3.

Code to iterate over Map which is a list of String.

Sightly (HTL)

<sly data-sly-use.table="${'my.models.Table'}">

     <div>

          <table data-sly-list.row="${table.rowList}">

               <tr data-sly-list.columnCell="${table.rowList[row]}">

                    <td>

                          ${columnCell}

                    </td>

               </tr>

          </table>           

     </div>

</sly>

Model Java:

Map<Integer,List<String>> myMap = new HashMap<Integer,List<String>>();

    for(int i=1;i<=3;i++)

    {

         List<String> list = new ArrayList<String>();

         list.add("" + i);

         list.add("" + i*i);

         list.add("" + i*i*i);

         myMap.put(new Integer(i-1),list);

    }

This sightly code stops working where ${table.rowList[row]} always returns null and hence inner loop does not execute.

Is there any change in 6.3 with respect to sightly where rowList[row] kind of notation is disabled ? Could not find something similar on google.

I also tried iterator way and passed the item in the array index. But that also does not solve the issue.
