ListItemDrag.direction is not defined in the API document

[XiaoGuo, Liu]

I just compared the two API documents:

https://developer.ubuntu.com/api/apps/qml/sdk-15.04.1/Ubuntu.Components.ViewItems/

it uses the code:

  ViewItems.onDragUpdated: {
       if (event.direction == ListItemDrag.Dropped) {
           // this is the last event, so drop the item
           model.move(event.from, event.to, 1);
       } else if (event.direction != ListItemDrag.Started) {
           // do not accept the moving events, so drag.from will
           // always contain the original drag index
           event.accept = false;
       }
   }

It has the "event.direction" there, but in the API document:

https://developer.ubuntu.com/api/apps/qml/sdk-15.04.1/Ubuntu.Components.ListItemDrag/

It does not have the "direction" property defined there. Is this a bug? Shall it be "event.status" instead?

Thanks & best regards,
