dataScroller reports wrong error when for attrib unresolvable
-------------------------------------------------------------

         Key: MYFACES-330
         URL: http://issues.apache.org/jira/browse/MYFACES-330
     Project: MyFaces
        Type: Bug
    Versions: Nightly Build    
    Reporter: Mike Kienenberger
    Priority: Minor
 Attachments: HtmlDataScroller.patch.txt

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'
