Spurious Error Message

[Rob Williams]

We have an SMTP handler on our production log set to WARNING and  
SEVERE and we are getting deluged with these messages:

Apr 2, 2005 5:45:14 PM  
org.apache.myfaces.renderkit.html.HtmlGridRenderer encodeEnd
SEVERE: Wrong columns attribute for PanelGrid quickSearch:_id1:_id13:  
-2147483648

I did some searches and didn't turn up much. How can this be a severe  
error?

Thanks,
Rob
