------------------------------------------------------
Hey, guys, I do indeed need such fine controll that Jorge described. I was
studying the problem and concluded that a good solution was already proposed
here, in this ticket. That is, in file AbstractHtmlDataScroller.java, move line
number 254 where you read
broadcastToActionListener(scrollerEvent);
to below the line 333 so that it reads
}
broadcastToActionListener(scrollerEvent);
}
It makes a lot more sense to me this way.

> Project: MyFaces Tomahawk
> Issue Type: Improvement
> Components: Data Scroller
> Affects Versions: 1.1.5-SNAPSHOT
> Environment: Windows XP, jakarta-tomcat-5.0.28.
> Reporter: Jorge Andrés Vásquez
> Priority: Minor
>
> The the HtmlDataScroller class is currently using the actionListener event
> (in particular the ScrollerActionEvent) to maintain the firstRow index of the
> dataTable. My idea is that if someone needs to control this variable from
> inside a managed bean for example in order to maintain the page number in a
> master/detail scenario then that person can use this actionEvent too. But in
> order for broadcast method of HtmlDataScroller component class to not
> overwrite the control logic that one can implement from the bean the
> suggestion is to modify method: "public void broadcast(FacesEvent event)"
> changing the broadcastToActionListener(scrollerEvent); to the end of the if
> (event instanceof ScrollerActionEvent)...portion of the code. This change
> allows anyone to control the rowIndex from a bean with a simple event-based
> logic.
