> If the "for" attribute for dataScroller is unresolvable, the following error is thrown.
> uiComponent referenced by attribute dataScroller@for must be of type javax.faces.component.UIData
> java.lang.IllegalArgumentException: uiComponent referenced by attribute dataScroller@for must be of type javax.faces.component.UIData
> Here's a patch that improves the output of the above message: 
> Ie:
> java.lang.IllegalArgumentException: uiComponent referenced by attribute dataScroller@for = 'form' must be of type javax.faces.component.UIData, not type javax.faces.component.html.HtmlForm
> and also throws an exception (rather than just logging a warning) if the for attribute is unresolved (otherwise, myfaces will crash later with an exception that is more difficult to track down.
> java.lang.IllegalArgumentException: could not find UIData referenced by attribute dataScroller@for = 'form'
