Hi Guillaume,
thanx for your answer. The workaround is better than showing the old
templates but understanding the issue would be even better.
Anyway, I'm happy now that I at least have the blank line again. Maybe
someone else being more familiar with the XWiki internals has dome
ideas.
Thanx again for your time Guillaume,
Sebastian

Hi again,
I still don't fully understand, what was causing the issue, but I came
nearer I think. I don't know, whether this goes into the direction of
being a bug or just a misuse of XWiki by myself. I'll try to describe,
what I did that ended in the problem of the blank line not being
there.
1. I had classes AClass, BClass and CClass which had some set of
properties defined.
2. Based on them I created some documents, lets call the
ADoc1,..,ADocn, BDoc1,...,BDocn and so on.
3. I decided, I need a new class called DClass, that should on the one
hand wrap together some of the documents of classes A,B,C and on the
other hand replace the need for some properties in AClass, BClass and
CClass.
4. Consequently I renamed AClass,... to AClassOld (I don't know if its
allowed to let a class end in some different literal than Class),
further I went on and renamed the template to AClassTemplateOld,...
and did the same with the Sheet.
5. I recreated AClass, BClass, CClass with a subset of the original
properties and recreated the Template and Sheet as well.
6. I found that everything worked to my expectations, so I removed all
the class files ending in "Old".
-> This is, what made the issue appear!!!
To be precise, removing AClassTemplateOld,... is enough, as I just
found out, after removing these again from my again working backup I
put into my XWiki yesterday.
The reason I removed the "Old" template files again is, that they get
shown by running this code:
#set($sql = ", BaseObject as obj where obj.name=doc.fullName and
obj.className='XWiki.${class}Class' and
obj.name<>'XWiki.${class}ClassTemplate'")
#foreach ($item in $xwiki.searchDocuments($sql))
* [$item.substring($mathtool.add($item.indexOf("."),1))>$item]
#end
If you do not want the old templates to be shown, you can simply modify the
query code as follows :
#set($sql = ", BaseObject as obj where obj.name=doc.fullName and
obj.className='XWiki.${class}Class' and
obj.name<>'XWiki.${class}ClassTemplate' and
obj.name<>'XWiki.${class}ClassTemplateOld'")
#foreach ($item in $xwiki.searchDocuments($sql))
* [$item.substring($mathtool.add($item.indexOf("."),1))>$item]
#end
Basically, you can add this part :
and obj.name<>'DocumentSpace.DocumentName'
that tells the query to ignore some XWiki documents / objects when
retrieving matching documents.
So, it would be great if you could tell me, if I
did something wrong
in the sense that XWiki is not prepared to handle it technically. The
issue occuring by this (the missing blank line) remains logically
uncorrelated to what I did. I'm very interested of what is going on
there internally.
No idea about what may have happened underneath.
Another question I have is: How do I get rid now
of the old classes
AClassOld, BClassOld, CClassOld and all their templates and sheets
without ending in the blank line missing issue again.
Using the snippet I provided they won't show up in your query results. I
know that's only a workaround, but I'm not familiar enough with XWiki's
inner workings to do best ;-)
Hope this helps,
Guillaume
Many thanx for your discussion on this in
advance.
Cheers,
Sebastian

Hi again,
issue solved! but not understood yet.
Great :-)
I just remembered having a 5 day old export of my
whole wiki. I tried
that one and see, the issue is gone. :-)
I will look into it and see, if I find diffs which could have caused
the trouble.
Please file a JIRA issue if/when you manage to identify what the issue Thanks,
Guillaume
