[xwiki-devs] Oracle / Language Issues

I've tracked down the language issues I've run into to a hibernate query select doc.language from XWikiDocument as doc where doc.web = 'Main' and doc.name = 'WebHome' and doc.language <> '' This will never return results in Oracle because of the way oracle treats nulls and black strings. Is there an xWiki fix for this???? I'm using xWiki 1.3.1.8931 and Oracle 9. Thanks, Jeff
