When using document templates, the template is fully copied, including selected values. When you say you could deselect the selected value, do you mean that you could Ctrl+Click, or that there was a blank row you could select? If it was Ctrl+Click, check the multiselect setting for the property. -- Sergiu Dumitriu http://purl.org/net/sergiu/

Hi guys, thanx Sergiu for your reply. I create documents based on a class which defines database list properties. I did not change anything in that class between when "the blank row" in the selection box in inline editing mode was present and now where it disappeared for new documents. BTW, in this particular case I do not have multiselect enabled. The alphabetically first entry is selected as the blank row isn't there anymore. Any ideas? Help is desperately needed. Thanx for all input in advance. Cheers, Sebastian On Mon, Mar 9, 2009 at 4:11 PM, Sergiu Dumitriu <sergiu(a)xwiki.com> wrote:

Hi, how can I check what happened to my class, that the blank row is missing now in new objects. It would be really nice if you could help me with this. I desperately need the DBList property to have nothing selected in the default state. Many, many thanx in advance.

Hi Guillaume, man thanx for your reply. Apparently something inside my XWiki instance is broke. As I wanted to try what you suggest I found that any new class I define with a DBListProperty has that "blank" line missing :-( As I said before, the already existing objects still have it when editing them. The question now is, where the blank line is actually coming from, i.e. where in XWiki's architecture does it get inserted. Maybe the issue can easily be fixed?

Hi again, issue solved! but not understood yet. 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.

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 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. 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. Many thanx for your discussion on this in advance. Cheers, Sebastian On Wed, Mar 11, 2009 at 3:56 PM, Guillaume Lerouge &lt;guillaume(a)xwiki.com&gt; wrote:

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.

Hi guys, I got to pop up this issue once more as I need help with something very related to it: I just recognized, that the blank line that I need in my DBLists is coming from the ClassTemplate that has an "empty object" on it. My hibernate statement is the following: "select prop.value from BaseObject as obj, StringProperty as prop where obj.className='XWiki.ServicesComponentClass' and prop.id.id=obj.id and prop.id.name='name' order by prop.value" The empty line, I was all the time talking about was coming from the Template of the class which had an empty property as its object was empty. For some reason this did not work any more for the template of my class itself (still not solved), but needed some other "empty" object added to any document. So I got my empty line. Now I want to change the query to this: "select doc.name from XWikiDocument doc, BaseObject as obj where obj.className='XWiki.ServicesComponentClass' and doc.fullName=obj.name order by doc.name" so actually returning me the document names of the specific class instead of the 'name" property as before. Based on my assumption what is causing a blank line in the DBList selection, how can I get a blank line in such a query, as this would need a document without a name, which is of course not possible.

Hi Guillaume, this indeed is ugly ;-), but it does the trick. :) Thanx. Isn't there a way, as I'm not to familiar with sql and hql to get an empty line from my result. So like selecting what I select in my query and additionally pseudoselect NULL or something? If something like this can be done in HQL, I would be interrested in how to do it.
