Adam Winer commented on TRINIDAD-93:
------------------------------------

Venkata, "first" does not come from the data model.  It's a component attribute.
No one should ever set it to < 0.

> UIXIterator._fixupFirst has some logic to fix the first attribute. If the first attribute is != 0 there is some logic to scroll the dataModel to the  end so that "first" row is available. This is extremely inefficient since the dataModel may have a large number of rows.
> This logic also does not account for the dataModel returning first < 0. If the first is < 0 the first should be assumed to be 0.
> Providing a patch so that if dataModel is returning first<0, the first is set to 0.
