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 is trying to fix the first if the first is < 0

> Key: TRINIDAD-93
> URL: https://issues.apache.org/jira/browse/TRINIDAD-93
> Project: MyFaces Trinidad
> Issue Type: Bug
> Components: Archetype
> Affects Versions: 1.0.1-core, 1.0.2-core, 1.2.1-core, 1.2.2-core
> Reporter: Venkata Guddanti
> Attachments: trunk.patch

>
> 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.
