Yes, inside the column you do not have access to the row index, only
to the column index. apparently this is your first column.

 Thanks very much.

Item.getIndex() on DefaultDataTable

2008-06-05 Thread Flavius

I'm using a DefaultDataTable and I want to get the index of the selected
item.  However the index always returns 0.  Is this by design?

IModel model)
{
int selectedIndex = item.getIndex();  //this 
always returns 0;  
}

{
@Override
protected void populateItem(final Item item)
{
int selectedIndex = item.getIndex();  
//increments by 1 with each
