Re: [xwiki-users] FW: xwiki 2.0, task manager application, Error number 4001 in 4: Error while parsing velocity page TasksCode.NewTask

3 Oct 2009

Thanks Ludivic,

I am running it on two systems based on MySQL Server 5.4.1 (my playground) and 5.1.39 the
production system.
However the point should be somewhere on the wiki farm:  It's running well on the
single wikis on the same configuration.

Now I've taken the query into a new page - using the group by or not:

#set($sql = "select max(prop.value)+1 from BaseObject as obj, IntegerProperty as prop
where obj.className='TasksCode.IssueClass' and obj.id=prop.id.id and
prop.id.name='id' group by obj.className")
#set($id = $xwiki.search($sql))
* $id

The result:
[] (two square brackets)

Running it like

#set($id = $xwiki.search($sql).get(0))

leads to error 4001.

Thanks
mb

However the query is going to get slower and slower.

Wasn't it just because you had no tasks at all that it returns empty ?
(I suppose you have check that but it's just to be sure)

Could you try the query with a group by..

Now if your DB does not accept this query it's not so good. Which
database and version are you using ?

  Hi Ludovic,

 I seems to work using

 #set($id = 1)
 #set ($list = $xwiki.searchDocuments(",BaseObject as obj, IntegerProperty as prop
 where
 doc.fullName=obj.name
 and obj.className='TasksCode.IssueClass'
 and obj.id=prop.id.id
 and prop.id.name='id'
 and prop.id.value > 0
 order by prop.id.value desc
 ", 0, 0))
 #foreach ($item in $list)
   #set($id = $id + 1)
 #end

 Thanks & Kind regards

 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

 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.

  Hi Community,

 I am sorry bothering you.  However I am using the task manager application in a
production environment, therefore I have to decide about staying on several single wikis
or consolidating them in a farm.

 Is there anybody available instructing me to find that bug?

 I am quite familiar writing code in general; however I haven't done something in
Java, eclipse or xwiki yet.  Therefore I would appreciate a link to some useful code
snippet as well.

 Thanks for now and in advance
 mb

 Hi all,

 I am running xwiki 2.0 in a farm.  The Task Manager Application fails creating a new
task.  Any hints?

 Thanks
