It was Jan Kodera who posted Nov 25, 2007; 06:34pm: (found, with a partial answer on Nabble: http://www.nabble.com/Database-List-Class-td13937776.html) I also wanted to have this... namely... to be able to list all the values of the property prop of each object. I tried, running XWiki 1.1.2.5797: - for a property fromList, of type database-list-class - I tried leaving all to default except adding class-name XWiki.MyClass, id-field-name xId and value-field-name xValue - then tried to create an object using the default sheet: this gave a hibernate exception, namely, that a comma is too much before the from (the whole query is provided in the log) - I re-edited the class, removed class and fields and replaced by the query with the query removed: select idprop.value,valueprop.value from com.xpn.xwiki.doc.XWikiDocument as doc, com.xpn.xwiki.objects.BaseObject as obj, com.xpn.xwiki.objects.StringProperty as idprop, com.xpn.xwiki.objects.StringProperty as valueprop where doc.fullName=obj.name and obj.className='XWiki.MyClass' and obj.id=idprop.id.id and idprop.id.name='xId' and obj.id=valueprop.id.id and valueprop.id.name='xValue' and that worked! Boy... that was convoluted but this seems to be a very very very precious feature of XWiki which I would like to write a readme about. Is there an issue reported about this ? And, indeed, as Sergiu and Brandon indicate in the answer of the mail above, it is highly non-trivial to understand that there's an alternative between class,id,value and query. So I would also suggest to write this in the page (as simple text). paul PS: I only saw answers of Brandon and Sergiu, was there other?
