Hi Ludovic, It's the query ... #set($sql = "select max(prop.value)+1 from BaseObject as obj, IntegerProperty as prop where obj.className='ITSClasses.IssueClass' and obj.id=prop.id.id and prop.id.name='id'")
$xwiki.search($sql) It returns always an empty string. Even there are tasks already defined. I've spend some time using $xwiki.searchDocuments(...) to count the task pages ... but I couldn't fix it (It returns either no or all pages) Thanks mb -----Original Message----- From: users-boun...@xwiki.org [mailto:users-boun...@xwiki.org] On Behalf Of Ludovic Dubost Sent: Friday, October 02, 2009 9:44 AM To: XWiki Users Subject: Re: [xwiki-users] FW: xwiki 2.0, task manager application, Error number 4001 in 4: Error while parsing velocity page TasksCode.NewTask Hi Michael, I suspect it is the counter that retrieves the lastest task number. It is running a "search" query with a "select max() and we have seen some differences based on the MySQL/hibernate combination on the way this unique result is returned (as a number directly or as a 1 item list). It could be also because in your case it does not return anything (your need a first task) You should look at this call to "search" and check what it returns exactly and how to retrieve this max number This is the code #set($sql = "select max(prop.value)+1 from BaseObject as obj, IntegerProperty as prop where obj.className='ITSClasses.IssueClass' and obj.id=prop.id.id and prop.id.name='id'") #set($id = $xwiki.search($sql).get(0)) Maybe in your case #set($id = $xwiki.search($sql)) or #set($res = $xwiki.search($sql)) #if($res && $res.size()>0) #set($id = $xwiki.search($sql).get(0)) #else #set($id = 0) #end will work.
