Re: [xwiki-devs] Problem loading Watch.Reader Application

To add on, I am using Oracle 10g R1 and hibernate 3.2.5ga. This problem seem to lie on the hibernate portion where it failed to resolve the alias in the GROUP BY clauses in WatchSheets.WebHome document.The code causing this problem is as follow: ..... #set($tagsQuery = "select elements(entry.tags), count(*) from XWiki.FeedEntryClass asentry, XWikiDocument as doc, BaseObject as obj wheredoc.fullName=obj.name and obj.id=entry.id and doc.web='${doc.space}' group bycol_0_0_) #set($tagList = $xwiki.search($tagsQuery)) How can i resolve this issue or else the watch application could not be used.
